A review of routing protocols for mobile ad hoc networks

Abstract

The 1990s have seen a rapid growth of research interests in mobile ad hoc networking. The infrastructureless and the dynamic nature of these networks demands new set of networking strategies to be implemented in order to provide efficient end-to-end communication. This, along with the diverse application of these networks in many different scenarios such as battlefield and disaster recovery, have seen MANETs being researched by many different organisations and institutes. MANETs employ the traditional TCP/IP structure to provide end-to-end communication between nodes. However, due to their mobility and the limited resource in wireless networks, each layer in the TCP/IP model require redefinition or modifications to function efficiently in MANETs. One interesting research area in MANET is routing. Routing in the MANETs is a challenging task and has received a tremendous amount of attention from researches. This has led to development of many different routing protocols for MANETs, and each author of each proposed protocol argues that the strategy proposed provides an improvement over a number of different strategies considered in the literature for a given network scenario. Therefore, it is quite difficult to determine which protocols may perform best under a number of different network scenarios, such as increasing node density and traffic. In this paper, we provide an overview of a wide range of routing protocols proposed in the literature. We also provide a performance comparison of all routing protocols and suggest which protocols may perform best in large networks.

A Survey on Localization for Mobile Wireless Sensor Networks

“…In dynamic topologies, table data become outdated quickly, and route discovery must repeatedly be performed at a substantial cost in terms of power, time, and bandwidth. Fortunately, there is an active area of research dedicated to routing in mobile ad hoc networks (MANETs), and MWSNs can borrow from this work [22].…”

Algorithms for Failure Protection in Large IP-over-fiber and Wireless Ad Hoc Networks

“…Over the course of the last 10 years a large number of different MANET routing protocols have been proposed (see [32,35] for overviews). All these algorithms deal with the dynamic aspects of MANETs in their own way, using reactive or proactive behavior, or a combination of both.…”

A Simulation Study of Routing Performance in Realistic Urban Scenarios for MANETs

“…A significant part of the research efforts have focused on routing, which is particularly challenging in MANETs due to the extremely dynamic nature of these networks, and requires algorithms that work in a fully distributed way, are able to self-organize, and to show a robust and adaptive behavior. As a result, a number of MANET routing protocols have been designed so far (see [1][2][3] for overviews). However, due to the high cost and technological difficulty of setting up real MANET testbeds, most of research is carried out in simulation.…”
