A Survey on Wireless Mesh Networks and its Security Issues

Abstract

Wireless Mesh Networks (WMNs) are have secured a significant position in the technological world due to their unique characteristics. These networks are dynamic, selfhealing, and self-organizing in which the nodes reflexively set-up and maintain mesh connectivity with each other. Having these characteristics, WMNs enjoy great benefits such as low-upfront costs, reliability, and prompt troubleshooting. Despite all these fringe benefits, one of the greatest challenges in wireless mesh networks is that they are exposed to a number of hazardous security vulnerabilities. In this paper we investigate WMNs security attacks, security goals and various defense mechanisms for defending the attacks.
