Practical ad hoc networks have unique challenges, such as constant network topology changes, bandwidth-constrained connections and diverse wireless signal fading scenarios. This book presents the design and evaluation of novel and efficient control mechanisms for channel access scheduling and topology control functions in ad hoc networks. The work is based on the neighbor-aware contention resolution (NCR) algorithm, which use only local neighborhood information to achieve globally consistent decisions, thus applicable to solve various control problems in ad hoc networks that required high control overhead before. First, channel access protocols based on NCR are presented for ad hoc networks with omni-directional antennas, namely NAMA, LAMA, PAMA and HAMA, which correspond to node-, link-, pair-wise- and hybrid-activation multiple access protocols, respectively. Furthermore, the collision-free channel access functions for ad hoc networks that have unidirectional links or directional antennas are presented, which were difficult if not impossible to achieve without NCR. NCR-based topology management that constructs a backbone structure in ad hoc networks is presented as well.

Ad hoc networks have very unique features, such as dynamic topologies, relatively limited bandwidth and wireless signal propagation schemes, which present difficult challenges for wireless communication. We propose control mechanisms for channel access scheduling and topology control in ad hoc networks, respectively, which utilize the neighborhood information within two hops to cope with the difficulties of communicating in ad hoc networks. First, we present the neighbor-aware contention resolution (NCR) algorithm, and analyze its generic performance with regard to the contention delay and system throughput. The required neighbor information in NCR for ad hoc networks is acquired through the neighbor protocol, which is based on a random channel access mechanism and a reliable message propagation scheme using retransmissions. Then, four channel access protocols based on NCR are presented, namely NAMA, LAMA, PAMA and HAMA, which correspond to node-, link-, pair- wise- and hybrid-activation multiple access protocols, respectively. These protocols are aimed at ad hoc networks with omnidirectional antennas, and their performance is analyzed. Furthermore, channel access protocols, adapted from NAMA and PAMA, are considered for heterogeneous ad hoc networks that include unidirectional links, which may occur due to power and signal propagation differences between wireless stations.

Principles of Ad Hoc Networking presents a systematic introduction to the fundamentals of ad hoc networks. An ad-hoc network is a small network, especially one with wireless or temporary plug-in connections. Typically, some of the network devices are part of the network only for the duration of a communications session or, in the case of mobile or portable devices, while in some close proximity to the rest of the network. These networks can range from small and static systems with constrained power resources to larger-scale dynamic and mobile environments. Wireless ad hoc networks facilitate numerous and diverse applications for establishing survivable dynamic systems in emergency and rescue operations, disaster relief and intelligent home settings. Principles of Ad Hoc Networking: Introduces the essential characteristics of ad hoc networks such as: physical layer, medium access control, Bluetooth discovery and network formation, wireless network programming and protocols. Explains the crucial components involved in ad-hoc networks in detail with numerous exercises to aid understanding. Offers key results and merges practical methodologies with mathematical considerations. Principles of Ad Hoc Networking will prove essential reading for graduate students in Computer Science, Electrical Engineering, Applied Mathematics and Physics as well as researchers in the field of ad hoc networking, professionals in wireless telecoms, and networking system developers.

In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.

Overview and Goals Wireless communication technologies are undergoing rapid advancements. The past few years have experienced a steep growth in research in the area of wireless ad hoc networks. The attractiveness of ad hoc networks, in general, is attributed to their characteristics/features such as ability for infrastructure-less setup, minimal or no reliance on network planning and the ability of the nodes to self-organize and self-configure without the involvement of a centralized n- work manager, router, access point or a switch. These features help to set up a network fast in situations where there is no existing network setup or in times when setting up a fixed infrastructure network is considered infeasible, for example, in times of emergency or during relief operations. Even though ad hoc 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 scalability, quality-of-service, energy efficiency and security.
