Download or read book Distributed Dynamic Channel Access Scheduling for Ad Hoc Networks written by and published by . This book was released on 2002 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three types of collision-free channel access protocols for ad hoc networks are presented. These protocols are derived from a novel approach to contention resolution that allows contending entities to elect one or multiple winners for channel access in any given contention context (e.g., a time slot) in a distributed fashion. In multihop wireless networks, the only required information for each entity is the identifiers of its neighbors one and two hops away. The new protocols are shown to be fair and capable of achieving maximal utilization of the channel bandwidth. The delay and throughput characteristics of the contention resolution algorithms are analyzed, and the performance of the three types of channel access protocols is studied by simulations and compared with that of optimal static scheduling algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: A new family of collision-free channel access protocols for ad hoc networks with unidirectional links is introduced. These protocols are based on a distributed contention resolution algorithm that operates at each node based on the list of direct contenders (one-hop neighbors or incident links) and indirect interferences (two-hop neighbors and related links). Depending on the activation scheme (node activation or link activation), a network node uses the identifiers of its neighbors one and two hops away to elect deterministically one or multiple winners for channel access in each contention context (e.g., a time slot or a frequency band). The protocols are shown to be fair and capable of achieving maximum utilization of the channel bandwidth. The delay and throughput characteristics of the channel access protocols is studied by simulations.

Download or read book Hybrid Channel Access Scheduling in Ad Hoc Networks written by and published by . This book was released on 2002 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the hybrid activation multiple access (HAMA) protocol for ad hoc networks. Unlike previous channel access scheduling protocols that activate either nodes or links only, HAMA is a node-activation channel access protocol that also maximizes the chance of link activations using time- and code-division schemes. HAMA only requires identifiers of the neighbors within two hops from each node to schedule channel access. Using this neighborhood information, each node determines whether to transmit in the current time slot on a dynamically assigned spreading code. A neighbor protocol supplements HAMA with up-to-date two-hop neighborhood information by reliably propagating the one-hop neighbor updates through a novel random access technique. The throughput and delay characteristics of HAMA in randomly-generated multihop wireless networks are studied by analyses and simulations. The results of the analyses show that HAMA achieves higher channel utilization in ad hoc networks than a distributed scheduling scheme based on node activation, similar throughout as a well-known scheduling algorithm based on complete topology information, and much higher throughout than the ideal CSMA and CSMA/CA protocols.

Abstract: Abstract of thesis entitled "Distributed Scheduling in Multihop Ad Hoc Networks" Submitted by Sun Yijiang for the degree of Master of Philosophy at The University of Hong Kong in February 2008 A multihop ad hoc network is a network formed by multiple nodes with- out the aid of any centralized administration, and data traffic is typically forwarded by multiple intermediate nodes before reaching its destination. In this thesis, we focus on improving QoS of end-to-end traffic flows in multihop ad hoc networks through packet transmission scheduling. Our approach was to design a framework in which existing schedul- ingalgorithmsoriginallydesigned forinfrastructure-basedwirelessnetworks could be adapted to multihop ad hoc networks. While infrastructure-based wireless scheduling has been studied extensively and most of the proposed algorithms handle the characteristics of wireless medium in an effective and fairway, ourapproach aimstogeneralizetheadaptationofthese algorithms to ad hoc networks and thus to make maximum use of the existing resource of wireless scheduling. iThe framework consists of two sets of mechanisms. The first one is an end-to-end service compensation mechanism. Each multihop flow is asso- ciated with some QoS requirement, which is requested and granted in the form of the desired service rate. The achieved rate is estimated at the des- tination and fed back to the source periodically. Both the desired rate and achieved rate of a multihop flow are propagated from the source node to all its downstream relaying nodes. With this information, a compensation- capable scheduling algorithm originally designed for infrastructure-based wireless networks can be adapted to each ad hoc node for error compensa- tion. The second part of the framework is a set of mechanisms for distributed opportunistic scheduling in multihop wireless ad hoc networks. The frame- work includes a wireless link state estimation mechanism, a requirement on medium access control protocol and two mechanisms to limit the access of the wireless medium. The link state estimation mechanism provides the necessary status of each wireless link and thus enables the adaptation of various opportunistic scheduling algorithms. The performance ofthe proposed framework was evaluated by computer simulations.

This book was released on 2003 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of the wireless networks has brought the issue of fair allocation of bandwidth among the users. Besides the issues in wired networks scheduling, wireless network has to take into account the characteristics of wireless channel, such as channel errors, location dependent contention, hidden or exposed stations, spatial channel reuse, and constraints in mobile hosts processing power and battery power. Medium Access Control (MAC) protocols define rules for orderly access to the shared medium and play a crucial role in the efficient and fair sharing of scarce wireless bandwidth. The IEEE standard 802.11 specifies the wireless LAN protocols for both infrastructure-based and ad-hoc networks. The previous studies in ad-hoc networks have assumed error free channel. However, in the wireless domain, a packet flow may experience location-dependent channel error and hence may not be able to complete transmission. The bursty channel errors can render the previous studies inapplicable. This study developed a fairness model for fair scheduling to deal with channel error in wireless ad-hoc networks. The throughput of the network is increased while the fairness is maintained in the model. The model was implemented in a distributed manner by localizing the global information required by the users of the networks. The simulation results showed the scheduling model achieves higher throughput and maintains the fairness at the same time.

Book excerpt: "This thesis presents a novel distributed fair scheduling and routing protocols for wireless ad hoc and sensor networks. Since fairness is an important issue when the wireless nodes access a shared channel, the proposed adaptive and distributed fair scheduling (ADFS) scheme allocates the channel bandwidth in proportion to the weight of the packet flows ... In addition, a novel optimized energy-delay routing (OEDR) protocol is presented, which generates routes based on delay, energy efficiency and state of the radio channel."--Abstract, leaf iii.

Available in PDF, EPUB and Kindle. Book excerpt: Next generation 4G LTE-Enhanced wireless cellular networks are designed to provide broadband high speed transport services to mobile users. Due to the scarcity of spectral resources that can be employed, it is essential for the networks to engage in multi-dimensional adaptations in the dynamic assignment of wireless access resources. The robustness of wireless cellular networks is also of importance, since failures or degradations of network elements inevitably lead to major network service disruptions. Thus, efficient failover mechanisms are required to handle this scenario. This dissertation introduces efficient adaptive scheduling algorithms for multicast and unicast downlink transmission operations in cellular wireless networks. Under multicast operations, the newly developed adaptive power scheduling algorithms enable base stations to coordinate, on a spatial-TDMA basis, the transmission of multicast packets to identified mobile users. This joint scheduling and power control problem is shown to be representable as a mixed-integer linear programming model, which is NP-hard. Consequently, heuristic algorithms of polynomial complexity are developed for solving the problem in a practical manner. These algorithms are shown to yield excellent throughput rate performance behavior, and to lower communications energy consumption levels. Under unicast networking operations, we introduce dynamic scheduling algorithms that allow busy base stations to make use of resources that remain under-utilized by lightly loaded neighboring base stations. Such a dynamically employed resource sharing mechanism is shown to provide significant enhancement to the system throughput capacity. Furthermore, the algorithms exhibit efficient performance behavior under failover scenarios. We also study multicast networking in wireless ad hoc networks. We consider an energy-aware mobile backbone network architecture under which certain nodes are dynamically elected to act as backbone nodes. Each backbone node manages the wireless access network that it controls, providing for the transport of messages from/to mobile clients and the Bnet. We introduce the concept of performing multicast packet distributions among the mobile ad hoc wireless network nodes using a hybrid multicast protocol. We show that the hierarchical Bnet based hybrid multicast architecture leads to efficient system performance behavior under different operational scenarios examined.

Download or read book A Protocol for Topology-Dependent Transmission Scheduling in Wireless Networks written by and published by . This book was released on 1999 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new channel access protocol for ad-hoc networks based on topology-dependent transmission scheduling, named collision-avoidance time allocation (CATA), is introduced. CATA allows nodes to contend for and reserve time slots by means of a distributed reservation and handshake mechanism. Contention is limited among nodes within two hops of one another, which provides a very efficient spatial reuse of the bandwidth available. CATA ensures that no collisions occur in successfully reserved time slots, even when hidden terminals exist. Reservations in CATA support unicasting, multicasting and broadcasting simultaneously, and adapt to dynamic service time. The throughput achieved by CATA is analyzed for the case of a fully-connected network topology. Numerical results show that CATA can achieve very high throughput.
