Packet switched networks provide an efficient and flexible method for interconnecting geographically distributed users for the purpose of digital data transmission. In packet radio networks, nodes transmit packets over multiple-access broadcast radio channels instead of wire, cable or fiber optics links. If the destination node of a packet is not within the power range of its source node, intermediate nodes are needed to deliver the packet in a store-and-forward fashion. Therefore, multihop packet radio networks have both the multiple-access feature typical of broadcast networks and the store-and-forward feature of point-to-point networks. Since only under restrictive assumptions is performance analysis tractable, simulation techniques must be used. (jes).

A packet radio network is a collection of geographically distributed packet radio units communicating over a shared broadcast channel. Usually not all radio units are within hearing range of each other, and thus multihop operation is required. These networks represent the natural extension of point-to-point packet-switched data networks when mobile operation is desired. An important difference exists, however, with respect to the latter: due to the multiaccess nature of the radio channel, the success of a packet at a destination depends on the activity, during the transmission of the packet, of the neighbors of the destination, and on system parameters such as the type of signaling and received power levels. The conditions under which a packet is successfully received in the presence of interfering packets are designated as the capture mode. Due to the existence of multiuser interference, some form of coordination among the users is required when accessing the channel. This purpose is accomplished by the channel access protocol. (RRH).

In this report, the performance of various channel access schemes in multi-hop packet radio networks with a regular structure is studied by means of simulation. The channel access schemes considered are: ALOHA (pure and slotted), Carrier Sense Multiple Access (CSMA), Busy Tone Multiple Access (BTMA), Code Division Multiple Access (CDMA), and a new hypothetical scheme introduced here for comparison purposes referred to as Coded Activity Signalling Multiple Access (CASMA. Network throughput and packet delay are evaluated, as well as the effects on performance of the nodal transmission scheduling rate, the propagation delay among nodes, and to some extent the input flow control. In this study, we consider networks in which both the topology and the traffic pattern are symmetric. This renders all nodes in the network statistically identical, and thus helps reduce the complexity of the simulation task considerably without jeopardizing the objective. The performance of CSMA in such networks is shown to be rather poor as compared with its performance in fully connected networks, while relatively high performance is achieved by the CASMA scheme, as compared with CSMA and the ALOHA schemes.

Cognitive radios (CR) technology is capable of sensing its surrounding environment and adapting its internal states by making corresponding changes in certain operating parameters. CR is envisaged to solve the problems of the limited available spectrum and the inefficiency in the spectrum usage. CR has been considered in mobile ad hoc networks (MANETs), which enable wireless devices to dynamically establish networks without necessarily using a fixed infrastructure. The changing spectrum environment and the importance of protecting the transmission of the licensed users of the spectrum mainly differentiate classical MANETs from CR-MANETs. The cognitive capability and re-configurability of CR-MANETs have opened up several areas of research which have been explored extensively and continue to attract research and development. The book will describe CR-MANETs concepts, intrinsic properties and research challenges of CR-MANETs. Distributed spectrum management functionalities, such as spectrum sensing and sharing, will be presented. The design, optimization and performance evaluation of security issues and upper layers in CR-MANETs, such as transport and application layers, will be investigated.

With the rapidly increasing penetration of laptop computers and mobile phones, which are primarily used by mobile users to access Internet s- vices like e-mail and World Wide Web (WWW) access, support of Internet services in a mobile environment is an emerging requirement. Wireless n- works have been used for communication among fully distributed users in a multimedia environment that has the needs to provide real-time bursty traffic (such as voice or video) and data traffic with excellent reliability and service quality. To satisfy the huge wireless multimedia service demand and improve the system performance, efficient channel access methods and analytical methods must be provided. In this way very accurate models, that faithfully reproduce the stochastic behavior of multimedia wireless communication and computer networks, can be constructed. Most of these system models are discrete-time queueing systems. Queueing networks and Markov chains are commonly used for the p- formance and reliability evaluation of computer, communication, and m- ufacturing systems. Although there are quite a few books on the individual topics of queueing networks and Markov chains, we have found none that covers the topics of discrete-time and continuous-time multichannel mul- traffic queueing networks. On the other hand, the design and development of multichannel mul- hop network systems and interconnected network systems or integrated n- works of multimedia traffic require not only such average performance m- sures as the throughput or packet delay but also higher moments of traffic departures and transmission delay.
