Abstract: In this paper, we investigate the principal issues and challenges pertaining to the security of Wireless Mesh Networks (WMNs). We study the threats a WMN faces and the security goals to be achieved. WMN is a new wireless networking model. Unlike traditional wireless networks, WMNs do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. Wireless internet service providers are choosing WMNs to offer Internet connectivity, as it allows a fast, easy and inexpensive network deployment. The main challenge in design of these networks is their vulnerability to security attacks. WMNs offer an easy and economical alternative for providing broadband wireless internet connectivity and could be termed as Web-in the sky. These networks have the ability to organize and configure themselves dynamically. These networks provide improved flexibility, efficiency and coverage as compared to the conventional networks. In place of a wired connection, WMN forms a wireless connectivity thus eliminating the need for extensive cabling. They are based on multihop communication patterns that form a dynamically connected network. However,multihop wireless communication networks are facing limitations such as a low throughput and they are also plagued with several security issues.
