Book Description
Mobile ad hoc networks represent a new approach towards computer networking which does not depend on an infrastructure for its operation. This flexibility gives rise to new applications of networks which were not possible with the networks that critically depend on an infrastructure for their operation. However this absence of infrastructure also gives rise to a host of problems with the network operation. Routing data from a source to destination is one such problem. Mobility of the nodes causes frequent topological changes and further complicates the problem. Many protocols have been proposed to help route data in mobile ad hoc networks. A sub class of these protocols makes use of a set of multipath routes to transmit data from the source to the destination. During the course of our research we discovered inefficiencies associated with these routing protocols. We have proposed the reuse of cached routes as a technique to reduce these inefficiencies and improve the performance of mobile ad hoc network along various performance parameters. We have proposed a new multipath routing protocol called CMR that makes use of the technique of reusing cached routes in determining new routes. Through extensive simulation experiments we have been able to analyze the performance of new protocol and demonstrate its advantages.

Book Description
Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes that move freely and self-configure without a preexisting communication infrastructure. In MANETs, under the arbitrary movement of nodes and highly dynamic topology conditions, the routing protocols for fixed networks do not perform well. To adapt to the rapid change of topology, many routing protocols have been proposed. However, most of them chose the minimum hop-count routes. This choice can lead to significant reduction of the network performance because communication quality via the chosen links is not good. Thus, the evaluation of link quality is indispensable and interference is a key factor to be considered. In the literature, most of the existing interference-aware protocols are single path and the consideration for interference range is limited. Several proposed interference-aware multi-path protocols for MANETs are either not highly efficient or have the computational complexity of NP-hard.To tackle the above problems, we first determine an interference region of each link including all nodes that can interfere with this link. Then, we propose a formula to evaluate the interference level of each link. Based on the formula of the link interference, we develop a series of interference-aware multi-path routing protocols for mobile ad hoc networks. These interference-aware multi-path routing protocols minimize the impact of interference on the paths from the source to the destination to increase the network performance. The computational complexity of the protocols is polynomial and each of them is most suitable for a type of network size. To demonstrate the efficiency of the interference-aware multi-path routing protocols, we compare them to prominent protocols in different network sizes and a high mobility environment when the RTS/CTS (Request-To-Send/Clear-To-Send) mechanism is alternatively turned on and turned off. The simulation results show that our protocols significantly improve packet delivery fraction, and reduce end-to-end delay, routing overhead, and normalized routing load.The RTS/CTS mechanism is to restrict the collision caused by the hidden terminals. However, we indicate that the RTS/CTS mechanism is not suitable for mobile ad hoc network based on the simulation results.
