This book was released on 2013 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: "One of the main challenges that prevents the large-scale deployment of Wireless Sensor Networks (WSNs) is providing the applications with the required quality of service (QoS) given the sensor nodes' limited energy supplies. WSNs are an important tool in supporting applications ranging from environmental and industrial monitoring, to battlefield surveillance and traffic control, among others. Most of these applications require sensors to function for long periods of time without human intervention and without battery replacement. Therefore, energy conservation is one of the main goals for protocols for WSNs. Energy conservation can be performed in different layers of the protocol stack. In particular, as the medium access control (MAC) layer can access and control the radio directly, large energy savings is possible through intelligent MAC protocol design. To maximize the network lifetime, MAC protocols for WSNs aim to minimize idle listening of the sensor nodes, packet collisions, and overhearing. Several approaches such as duty cycling and low power listening have been proposed at the MAC layer to achieve energy efficiency. In this thesis, I explore the possibility of further energy savings through the advertisement of data packets in the MAC layer. In the first part of my research, I propose Advertisement-MAC or ADV-MAC, a new MAC protocol for WSNs that utilizes the concept of advertising for data contention. This technique lets nodes listen dynamically to any desired transmission and sleep during transmissions not of interest. This minimizes the energy lost in idle listening and overhearing while maintaining an adaptive duty cycle to handle variable loads. Additionally, ADV-MAC enables energy efficient MAC-level multicasting. An analytical model for the packet delivery ratio and the energy consumption of the protocol is also proposed. The analytical model is veried with simulations and is used to choose an optimal value of the advertisement period. Simulations show that the optimized ADV-MAC provides substantial energy gains (50% to 70% less than other MAC protocols for WSNs such as T-MAC and S-MAC for the scenarios investigated) while faring as well as T-MAC in terms of packet delivery ratio and latency. Although ADV-MAC provides substantial energy gains over S-MAC and T-MAC, it is not optimal in terms of energy savings because contention is done twice - once in the Advertisement Period and once in the Data Period. In the next part of my research, the second contention in the Data Period is eliminated and the advantages of contention-based and TDMA-based protocols are combined to form Advertisement based Time-division Multiple Access (ATMA), a distributed TDMA-based MAC protocol for WSNs. ATMA utilizes the bursty nature of the traffic to prevent energy waste through advertisements and reservations for data slots. Extensive simulations and qualitative analysis show that with bursty traffic, ATMA outperforms contention-based protocols (S-MAC, T-MAC and ADV-MAC), a TDMA based protocol (TRAMA) and hybrid protocols (Z-MAC and IEEE 802.15.4). ATMA provides energy reductions of up to 80%, while providing the best packet delivery ratio (close to 100%) and latency among all the investigated protocols. Simulations alone cannot reflect many of the challenges faced by real implementations of MAC protocols, such as clock-drift, synchronization, imperfect physical layers, and irregular interference from other transmissions. Such issues may cripple a protocol that otherwise performs very well in software simulations. Hence, to validate my research, I conclude with a hardware implementation of the ATMA protocol on SORA (Software Radio), developed by Microsoft Research Asia. SORA is a reprogrammable Software Defined Radio (SDR) platform that satisfies the throughput and timing requirements of modern wireless protocols while utilizing the rich general purpose PC development environment. Experimental results obtained from the hardware implementation of ATMA closely mirror the simulation results obtained for a single hop network with 4 nodes"--Page vi-viii.

Available in PDF, EPUB and Kindle. Book excerpt: Wireless Sensor Networks (WSNs) and the Internet of Things are facing tremendous advances both in terms of energy-efficiency as well as in the number of available applications. Consequently, there are challenges that need to be tackled for the future generation of WSNs. After giving an overview of the WSN protocols and IEEE 802.15.4 standard, this book proposes IEEE 802.15.4 Medium Access Control (MAC) sub-layer performance enhancements by employing not only RTS/CTS combined with packet concatenation but also scheduled channel poling (MC-SCP). Results have shown that the use of the RTS/CTS mechanism improves channel efficiency by decreasing the deferral time before transmitting a data packet. Furthermore, the Sensor Block Acknowledgment MAC (SBACK-MAC) protocol enables more efficiency as it allows the aggregation of several acknowledgement responses in one special Block Acknowledgment (BACK) Response packet. The throughput and delay performance have been mathematically derived under both ideal conditions (a channel environment with no transmission errors) and non-ideal conditions (with transmission errors). Simulation results successfully validate the proposed analytical models. This research reveals the importance of an appropriate design for the MAC sub-layer protocol for the desired WSN application. Depending on the mission of the WSN application, different protocols are required. Therefore, the overall performance of a WSN application certainly depends on the development and application of suitable e.g., MAC, network layer protocols.

Book excerpt: Master's Thesis from the year 2013 in the subject Computer Science - Internet, New Technologies, grade: 8.12, , course: M. Tech, language: English, abstract: Wireless sensor network (WSN) is an emerging imperious leading technology of the current century that presents great promise for various pioneering applications. The use of sensor networks should keep developing, mainly in the fields of scientific, logistic, healthcare and military applications. Sensor networks interact and collect sensitive data and operate in unattended hostile environments, thus it is imperative to pay attention to the security of wireless sensor networks as they are highly prone to threats. For successful operation of the nodes, it is important to maintain the security and privacy of the transmitted data as well as the data stored at nodes. The different security protocols and models used in the wired and other wireless networks such as ad-hoc networks cannot be used in WSNs because the sensor size poses significant restrictions, mainly in terms of energy autonomy and node lifetime, as the batteries have to be too tiny. Also, the existing security protocols in these constrained networks are not sufficiently energy efficient, which is the real motivation behind this work. In this thesis, a light-weight dynamic security algorithm titled “An Energy Efficient and Dynamic Security Protocol (EEDSP)” for wireless sensor networks has been proposed and implemented at nodal level. We also implement an existing algorithm and then carry out the performance analysis of both the algorithms in terms of energy consumptions, node lifetime and memory requirements at source and intermediate nodes to verify the improvement in our protocol’s results.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of Wireless Sensor Nodes revolutionaries sensing and control application. The size of sensor node makes it ideal to be used in variety of applications, but this brings more challenges and problems especially as the capacity of onboard battery is limited. It is due to the very reason that initial research in the field of WSN especially on MAC targets mainly on the energy conservation and gives secondary importance towards other attributes of MAC protocols. These attributes includes latency, throughput, fairness and collision. This research keeping in view of current application requirements which demands QoS as well as energy conservation in static and mobile sensor networks proposes MAC protocols to meet these challenges. In this research to improve the efficiency of the collision resolution algorithms used in mainly contention based MAC protocols, an Improved Binary Exponential Backoff Algorithm is proposed. The main target of this protocol is to resolve the problem of access collision by employing interim backoff period. The protocol targets to improve upon the performance of conventional Binary Exponential Backoff Algorithm which suffers heavily from collision. The result shows significant reduction in collision which increases the efficiency of the network in terms of QoS and energy conservation. To eliminate the problem of collision which is one of the major sources of network performance degradation a novel Delay Controlled Collision Free contention based MAC is designed. The protocol uses novel delay allocation technique. DCCF also provides mechanism to achieve fairness among the nodes. Detailed analysis and comparative result shows substantial increase in throughput and decrease in latency as compared to Industrial standard of IEEE 802.15.4 CSMA/CA MAC. The research also proposed novel MAC protocols for mobile sensor networks. These protocols uses a methodology which is based upon signal strength of the beacon sent to the node from various neighbouring coordinators that enable the nodes to seamlessly enter from one cluster to another without any link loss and unnecessary delays in the shape of association. The proposed scheme is implemented over IEEE 802.15.4 enabling the standard to perform better with dynamic topology. Result shows that mobility adaptive 802.15.4 protocol shows improvement in QoS and conserve energy far better than the existing conventional CSMA/CA MAC standard. Also the algorithm is implemented over Delay Controlled Collision Free Mac protocol and a detail comparison is carried out with other mobility adaptive MAC protocols. The result shows significant decrease in latency as well as high gain in throughput and considerable reduction in energy as compared to the mobility adaptive MAC protocols. Finally in order to resolve fundamental problem of scalable network which suffers from bottleneck as more nodes in the last hop tries to send data towards the sink, a novel protocol is proposed which allows more than one node at a time to transmit the data towards the sink. The protocol named Simultaneous Multi node CSMA/CA enables the conventional industrial standard of IEEE 802.15.4 CSMA/CA protocol to allow more than one node to transmit the data towards the coordinator or sink node. The protocol out performs the existing standard and provides significant increase in QoS of the network.

Download or read book Energy Efficient and Quality of Service Aware Protocols for Wireless Sensor Networks written by Bashir Yahya and published by . This book was released on 2010 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis is to provide some of the basic building blocks that are necessary for wireless sensor networks, and that address their special characteristics. These basic building blocks are in the areas of medium access and routing. Medium Access Control (MAC) protocols define rules to access and control the shared medium and play a critical role in the efficient and fair sharing of wireless bandwidth. Provided that the radio transceiver unit is the most power consuming unit of a physical sensor node, large energy savings can be achieved at the link layer where the MAC protocol is controlling the usage of the radio. In this context, we have proposed three MAC protocols that address the problems of energy consumption, quality of service (QoS), and mobility in sensor networks. Routing protocols specifies how sensor nodes communicate with each other by disseminating information that enables these nodes to build routes between them and sink node(s). These protocols enable different types of traffic to be delivered and fused during delivery to limit the amount of control information exchange. We tackled the problem of routing in WSNs, and proposed two routing protocols. Our proposed protocols maximize network lifetime through balancing energy utilization among nodes in the network (using multiple paths rather than single path), provide QoS through the use of the service differentiation concept to allow high important traffic to reach the destination within time bounds, implement Forward Error Correction (FEC) techniques to increase resiliency to path failures and hence increases the probability that an enough portion of the data packet is received at the destination to recover the original data message without incurring excessive delay through data retransmissions. Our contribution in this thesis is not only to design energy efficient MAC and routing protocols , but we consider other issues like increasing throughput, minimizing transmission delay, improving scalability, and handling nodes mobility.
