Book Description
This book focuses on the design and analysis of protocols for cooperative wireless networks, especially at the medium access control (MAC) layer and for crosslayer design between the MAC layer and the physical layer. It highlights two main points that are often neglected in other books: energy-efficiency and spatial random distribution of wireless devices. Effective methods in stochastic geometry for the design and analysis of wireless networks are also explored. After providing a comprehensive review of existing studies in the literature, the authors point out the challenges that are worth further investigation. Then, they introduce several novel solutions for cooperative wireless network protocols that reduce energy consumption and address spatial random distribution of wireless nodes. For each solution, the book offers a clear system model and problem formulation, details of the proposed cooperative schemes, comprehensive performance analysis, and extensive numerical and simulation results that validate the analysis and examine the performance under various conditions. The last section of this book reveals several potential directions for the research on cooperative wireless networks that deserve future exploration. Researchers, professionals, engineers, and consultants in wireless communication and mobile networks will find this book valuable. It is also helpful for technical staff in mobile network operations, wireless equipment manufacturers, wireless communication standardization bodies, and governmental regulation agencies.

Book Description
Computer communication networks have come of age. Today, there is hardly any professional, particularly in engineering, that has not been the user of such a network. This proliferation requires the thorough understanding of the behavior of networks by those who are responsible for their operation as well as by those whose task it is to design such networks. This is probably the reason for the large number of books, monographs, and articles treating relevant issues, problems, and solutions in this field. Among all computer network architectures, those based on broadcast mul tiple access channels stand out in their uniqueness. These networks appear naturally in environments requiring user mobility where the use of any fixed wiring is impossible and a wireless channel is the only available option. Because of their desirable characteristics multiple access networks are now used even in environments where a wired point-to-point network could have been installed. The understanding of the operation of multiple access network through their performance analysis is the focus of this book.

Book Description
Ad hoc networks are gaining increasing popularity in recent years because of their ease of deployment. No wired base station or infrastructure is supported, and each host communicates one another via packet radios. In ad hoc networks, nodes are mobile which bring many challenges, such as network connectivity, topology change, link characteristic, and etc. In this research work, a novel model to analyze the link stability in mobile ad hoc networks is proposed. In the proposed analytical model, between each communicating pair, one node is considered to be stationary while the other moves relative to it. With this method, the mobility models defined in this dissertation can be approximated as a fluid flow model. Using the result of the fluid flow model, the analytical model for the link duration is obtained, which is used to obtain the link holding time and the link breaking probability of a communicating pair. The distribution of a routing path duration and the routing path breaking probability are also obtained by extending the models of the link duration and the link breaking probability. These results of link and routing path stabilities are serviced as ground knowledge to obtain the performance of medium access control (MAC) protocol considering node mobility. MAC protocols are a fundamental element that determines the efficiency in sharing the limited communication bandwidth of wireless channels. IEEE 802.11 distributed coordination function (DCF) MAC protocol is the most widely used MAC protocol in ad hoc networks due to its compatibility with the IEEE 802 protocol suite. Since the release of the IEEE 802.11 standard, many research efforts have been devoted to modeling the performance of this protocol. However, most of studies are confined to the stationary performance where the nodes are immobile. In this research work, we employ the link and routing path stability models to analyze the performance of the IEEE 802.11 DCF MAC protocol in dynamic environment. To the best of our knowledge, this is the first time to evaluate the performance of this protocol with mobility. Another contribution of this research work is to analyze the performance of the IEEE 802.11 DCF MAC protocol with capture effect. Currently, most analytical models assume that all received packets at the receiver have the same physical conditions (same power, same coding, etc), so when two or more nodes transmit their packets at the same time, the collision happens and all packets involved are destroyed, which may not be the case in reality due to capture effect. In this research work, we provide an analytical model to obtain the probability of capture effect. We use this probability of capture effect to analyze the throughput of the IEEE 802.11 DCF MAC protocol in ad hoc networks considering path loss, multipath fading, and shadowing. Wireless channel is time-varying and error prone. The packet transmission can be failed due to transmission errors. In this research work, a refined analytical model is presented to evaluate the performance of the IEEE 802.11 DCF MAC protocol with time-varying wireless channel. In the proposed model, the time-varying wireless channel is modeled by a finite-state Markov (FSM) chain. In each channel state, the operation of the IEEE 802.11 DCF MAC protocol is modeled by an embedded Markov chain. Using this model, the throughput of the DCF protocol can be theoretically calculated. The results show that the performance of the DCF protocol strongly depends on the network size, the incoming traffic loads, and the bit error rate (BER). When the incoming traffic load is light, the throughput increases when the network size grows. When the network works under heavy (saturated) condition, the throughput decreases when the network size grows. The throughput always degrades when increasing BER regardless the network size and the traffic load.
