Download or read book Load and Interference Aware Routing Metric for Wlan Mesh Networks written by Lan Tien Nguyen and published by LAP Lambert Academic Publishing. This book was released on 2011-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Mesh Networks recently attract significant interests due to the minimal infrastructure demands and their potential for supporting mobile and pervasive computing. This work introduces a routing scheme to find best performance routes in WLAN mesh networks. A cross-layer approach is used to overcome self-interference issue of existing load-aware routing metrics. The proposed routing metric was evaluated on a multi-hop wireless emulator which allows us to emulate wireless networks on a wired testbed. Design and implementation of AEROMAN (Architecture to Evaluate Routing Protocols for Multi-hop Ad-hoc Networks) used in the emulator are presented. AEROMAN is the first, to the best of our knowledge, fully distributed approach taking into account properties of contention-based media access for wireless channel, and does not require any special hardware to emulate wireless channel.

Available in PDF, EPUB and Kindle. Book excerpt: Wireless Mesh networks have the potential to provide inexpensive and quick access to the internet for military communications, surveillance, education, healthcare and disaster management. This work caters to the growing high-bandwidth demands by providing low delay and high throughput by designing efficient, robust routing algorithms for wireless mesh networks. Chapters 2 and 3 of this dissertation describe adaptive routing algorithms that opportunistically route the packets in the absence of reliable knowledge about channel statistics and the network model. We design two adaptive routing algorithms, Distributed Opportunistic Routing (d-AdaptOR) and No Regret Routing (NRR), which minimize the expected number of transmissions and thus improving the throughput. The remainder of the dissertation concerns with the design routing algorithms to avoid congestion in the network. In Chapter 4, we describe a Distributed Opportunistic Routing algorithm with Congestion Diversity (ORCD) which employs receiver diversity and minimizes end-end delay. In Chapter 5, we present the Congestion Diversity Protocol (CDP), a distributed routing protocol for 802.11-based multi-hop wireless networks that combines important aspects of shortest-path and back-pressure routing to achieve improved end-end delay performance. This work reports on a practical (hardware and software) implementation of CDP in an indoor Wi-Fi testbed.

Available in PDF, EPUB and Kindle. Book excerpt: It is my pleasure to write the preface for Information Processing and Management. This book aims to bring together innovative results and new research trends in inf- mation processing, computer science and management engineering. If an information processing system is able to perform useful actions for an obj- tive in a given domain, it is because the system knows something about that domain. The more knowledge it has, the more useful it can be to its users. Without that kno- edge, the system itself is useless. In the information systems field, there is conceptual modeling for the activity that elicits and describes the general knowledge a particular information system needs to know. The main objective of conceptual modeling is to obtain that description, which is called a conceptual schema. Conceptual schemas are written in languages called conceptual modeling languages. Conceptual modeling is an important part of requi- ments engineering, the first and most important phase in the development of an inf- mation system.

Available in PDF, EPUB and Kindle. Book excerpt: Overview and Goals Wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless sensor networks (WSNs). In WSNs, communication takes place with the help of spatially distributedautonomoussensornodesequippedtosensespeci?cinformation. WSNs, especially the ones that have gained much popularity in the recent years, are, ty- cally, ad hoc in nature and they inherit many characteristics/features of wireless ad hoc networks such as the ability for infrastructure-less setup, minimal or no reliance on network planning, and the ability of the nodes to self-organize and self-con?gure without the involvement of a centralized network manager, router, access point, or a switch. These features help to set up WSNs fast in situations where there is no existing network setup or in times when setting up a ?xed infrastructure network is considered infeasible, for example, in times of emergency or during relief - erations. WSNs ?nd a variety of applications in both the military and the civilian population worldwide such as in cases of enemy intrusion in the battle?eld, object tracking, habitat monitoring, patient monitoring, ?re detection, and so on. Even though sensor networks have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the well-known challenges are attributed to issues relating to coverage and deployment, scalability, quality-of-service, size, computational power, energy ef?ciency, and security.

Available in PDF, EPUB and Kindle. Book excerpt: Overview and Goals Wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless mesh networks (WMNs). The attractiveness of WMNs, in general, is attributed to their characteristics such as the ability to dynamically self-organize and self-con?gure, coupled with the ability to maintain mesh connectivity leading, in effect, to low set-up/installation costs, simpler maintenance tasks, and service coverage with high reliability and fault-tolerance. WMNs also support their integration with existing wireless networks such as cellular networks, WLANs, wireless-?delity (Wi-Fi), and worldwide interoperability of microwave access (WiMAX). WMNs have found u- ful applications in a broad range of domains such as broadband home networking, commercial/business networking, and community networking – particularly attr- tive in offering broadband wireless access with low initial installation and set-up costs. Even though WMNs have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the wellknownchallenges areattributedtoissuesrelatingtoscalability(signi?cantdrop in throughput with the increase in the number of nodes), multicasting, offering qu- ity of service guarantees, energy ef?ciency, and security. This handbook attempts to provide a comprehensive guide on fundamental key topics coupled with new ideas and results in the areas of WMNs. The book has been prepared keeping in mind that it needs to prove itself to be a valuable resource dealing with both the important core and the specialized issues in WMNs.

Available in PDF, EPUB and Kindle. Book excerpt: The rapid advancements in communication and networking technologies boost the capacity of wireless networks. Multi-hop wireless networks are extremely exciting and rapidly developing areas and have been receiving an increasing amount of attention by researchers. Due to the limited transmission range of the nodes, end-to-end nodes may situate beyond direct radio transmission ranges. Intermediate nodes are required to forward data in order to enable the communication between nodes that are far apart. Routing in such networks is a critical issue. Opportunistic routing has been proposed to increase the network performance by utilizing the broadcast nature of wireless media. Unlike traditional routing, the forwarder in opportunistic routing broadcasts date packets before the selection of the next hop. Therefore, opportunistic routing can consider multiple downstream nodes as potential candidate nodes to forward data packets instead of using a dedicated next hop. Instead of simply forwarding received packets, network coding allows intermediate nodes to combine all received packets into one or more coded packets. It can further improve network throughput by increasing the transmission robustness and efficiency. In this dissertation, we will study the fundamental components, related issues and associated challenges about opportunistic routing and network coding in multi-hop wireless networks. Firstly, we focus on the performance analysis of opportunistic routing by the Discrete Time Markov Chain (DTMC). Our study demonstrates how to map packet transmissions in the network with state transitions in a Markov chain. We will consider pipelined data transfer and evaluate opportunistic routing in different wireless networks in terms of expected number of transmissions and time slots. Secondly, we will propose a regional forwarding schedule to optimize the coordination of opportunistic routing. In our coordination algorithm, the forwarding schedule is limited to the range of the transmitting node rather than among the entire set of forwarders. With such an algorithm, our proposal can increase the throughput by deeper pipelined transmissions. Thirdly, we will propose a mechanism to support TCP with opportunistic routing and network coding, which are rarely incorporated with TCP because the frequent occurrences of out-of-order arrivals in opportunistic routing and long decoding delay in network coding overpower TCP congestion control. Our solution completes the control feedback loop of TCP by creating a bridge between the sender and the receiver. The simulation result shows that our protocol significantly outperforms TCP/IP in terms of network throughput in different topologies of wireless networks.

This book was released on 2022-06-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquakes are natural hazards under which disasters are mainly caused by damage to structures or collapse of buildings and other man-made structures. Shaking and ground rupture are the main effects created by earthquakes, principally resulting in more or less severe damage to buildings and other rigid structures. As the earth vibrates, all buildings on the ground surface will respond to that vibration in varying degrees. The horizontal ground motion action is similar to the effect of a horizontal force action on the building.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Wireless systems for industry have mostly used cellular-phone-style radio links, using point-to-point or point-to-multipoint transmission. Past research has indicated that these network architectures are not suitable for several industrial applications because of their rigid structure, meticulous planning requirements, and dropped signals. In contrast, wireless mesh networks are multi-hop systems in which devices assist each other in transmitting packets through the network, and they provide a reliable, flexible system that can be extended to thousands of devices. Some inherent advantages with mesh networks are scalability, non line-of-sight communications, high data rates, and low-cost deployment. Mesh networks have been deployed by MIT researchers and a few companies on a small scale. Mesh networks have not been deployed widely, in part because of some fundamental problems with the current protocols with regards to QoS support and scalability. To meet these requirements, the MAC protocol should be able to guarantee near constant capacity for networks of different sizes, and the routing protocol should perform admission control. Current CSMA-based MAC protocols have been shown to perform inadequately in terms of throughput and scalability in multi-hop deployments. The key problem with using protocols like IEEE 802.11 is that the link throughput is affected severely due to the exposed terminal problem, uncoordinated contentions, and wasteful backoffs. With the 802.11 MAC protocol, our results show that the capacity falls to about 1/10th for a chain and below 1/20th for a grid with horizontal constant bit rate flows. We have developed the WisperNet MAC and routing protocols, which provide end-to-end QoS guarantees over a multi-hop mesh network. By exploiting the topology information and the fact that fixed wireless nodes separated by 3 hops or more can transmit simultaneously, we eliminate collisions and maximize network utilization. The WisperNet routing protocol performs admission control. We show that the WisperNet MAC protocol can guarantee up to 9 times more capacity than IEEE 802.11, and this capacity remains nearly constant as the network grows. Also included is a performance analysis of different routing policies, and their effect on network utilization."
