This book was released on 2010-05 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, the performance of wireless ad hoc networks is investigated. First, a multi-copy relaying scheme for packets in mobile ad hoc networks (MANETs) is proposed, which reduces the delivery delay without changing the throughput order. Also, a method for computing the interference caused from other nodes is presented. Second, the trade-off among mobility, capacity, and delay for ad hoc networks is studied. By considering nodes that are subject to restrained movements, it is found that mobility is an entity that can be exchanged with capacity and delay. Moreover, the throughput-delay trade-off is investigated for nodes employing directional antennas and the results are compared with previous work. Third, a new communication scheme based on collaboration among nodes is proposed where the transmission of packets is concurrently possible by employing a many-to-many communication framework, i.e., multi-packet transmission (MPT) and multi-packet reception (MPR). The principles of operation for such technique and two practical examples of implementation using FDMA/CDMA and FDMA/MIMO are presented. Shannon capacity, throughput and delay are computed and compared with related works.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT : Mobile wireless ad hoc networks represent an important tool and technology to provide data communication in places where wired networks are not available. An ad hoc network is composed of mobile nodes without any infrastructure. Mobile nodes self organize themselves to form a network over radio links. Multicasting, which is the transmission of packets or data between a single sender and multiple receivers on a network, is used as a mode of transmitting information between these mobile nodes. In an ad hoc network, the benefits of using multicasting is that it is more bandwidth efficient than unicasting. In this thesis, a survey on some existing experimental studies and the performance metrics measured have been mentioned. Secondly, a prototype application-layer test bed program is implemented to investigate routing and how data is transmitted in wireless ad hoc networks. Thirdly, various experiments were performed in the indoor and outdoor environment varying distances and data sizes of packets. The results of this study show the actual performance of mobile wireless networks putting into consideration all natural effects that generally affect the wireless networks.

Available in PDF, EPUB and Kindle. Book excerpt: With modern communication networks continuing to grow in traffic, size, complexity, and variety, control systems are critical to ensure quality and effectively manage network traffic. Providing a thorough and authoritative introduction, Wireless Ad hoc and Sensor Networks: Protocols, Performance, and Control examines the theory, architectures, and technologies needed to implement quality of service (QoS) in a wide variety of communication networks. Based on years of research and practical experience, this book examines the technical concepts underlying the design, implementation, research, and invention of both wired and wireless networks. The author builds a strong understanding of general concepts and common principles while also exploring issues that are specific to wired, cellular, wireless ad hoc, and sensor networks. Beginning with an overview of networks and QoS control, he systematically explores timely areas such as Lyapunov analysis, congestion control of high-speed networks, admission control based on hybrid system theory, distributed power control of various network types, link state routing using QoS parameters, and predictive congestion control. The book also provides a framework for implementing QoS control using mote hardware. Providing a deeply detailed yet conveniently practical guide to QoS implementation, Wireless Ad hoc and Sensor Networks: Protocols, Performance, and Control is the perfect introduction for anyone new to the field as well as an ideal reference guide for seasoned network practitioners.

Available in PDF, EPUB and Kindle. Book excerpt: Benefiting from the constant and significant advancement of wireless communication technologies and networking protocols, Wireless Ad hoc NETwork (WANET) has played a more and more important role in modern communication networks without relying much on existing infrastructures. The past decades have seen numerous applications adopting ad hoc networks for service provisioning. For example, Wireless Sensor Network (WSN) can be widely deployed for environment monitoring and object tracking by utilizing low-cost, low-power and multi-function sensor nodes. To realize such applications, the design and evaluation of communication protocols are of significant importance. Meanwhile, the network performance analysis based on mathematical models is also in great need of development and improvement.This dissertation investigates the above topics from three important and fundamental aspects, including data collection protocol design, protocol modeling and analysis, and physical interference modeling and analysis. The contributions of this dissertation are four-fold.First, this dissertation investigates the synchronization issue in the duty-cycled, pipelined-scheduling data collection of a WSN, based on which a pipelined data collection protocol, called PDC, is proposed. PDC takes into account both the pipelined data collection and the underlying schedule synchronization over duty-cycled radios practically and comprehensively. It integrates all its components in a natural and seamless way to simplify the protocol implementation and to achieve a high energy efficiency and low packet delivery latency. Based on PDC, an Adaptive Data Collection (ADC) protocol is further proposed to achieve dynamic duty-cycling and free addressing, which can improve network heterogeneity, load adaptivity, and energy efficiency. Both PDC and ADC have been implemented in a pioneer open-source operating system for the Internet of Things, and evaluated through a testbed built based on two hardware platforms, as well as through emulations.Second, Linear Sensor Network (LSN) has attracted increasing attention due to the vast requirements on the monitoring and surveillance of a structure or area with a linear topology. Being aware that, for LSN, there is few work on the network modeling and analysis based on a duty-cycled MAC protocol, this dissertation proposes a framework for modeling and analyzing a class of duty-cycled, multi-hop data collection protocols for LSNs. With the model, the dissertation thoroughly investigates the PDC performance in an LSN, considering both saturated and unsaturated scenarios, with and without retransmission. Extensive OPNET simulations have been carried out to validate the accuracy of the model.Third, in the design and modeling of PDC above, the transmission and interference ranges are defined for successful communications between a pair of nodes. It does not consider the cumulative interference from the transmitters which are out of the contention range of a receiver. Since most performance metrics in wireless networks, such as outage probability, link capacity, etc., are nonlinear functions of the distances among communicating, relaying, and interfering nodes, a physical interference model based on distance is definitely needed in quantifying these metrics. Such quantifications eventually involve the Nodal Distance Distribution (NDD) intrinsically depending on network coverage and nodal spatial distribution. By extending a tool in integral geometry and using decomposition and recursion, this dissertation proposes a systematic and algorithmic approach to obtaining the NDD between two nodes which are uniformly distributed at random in an arbitrarily-shaped network.Fourth, with the proposed approach to NDDs, the dissertation presents a physical interference model framework to analyze the cumulative interference and link outage probability for an LSN running the PDC protocol. The framework is further applied to analyze 2D networks, i.e., ad hoc Device-to-Device (D2D) communications underlaying cellular networks, where the cumulative interference and link outage probabilities for both cellular and D2D communications are thoroughly investigated.
