Wireless mesh networks are fast becoming the preferred way to deliver voice, video and data in outdoor environments. A wireless mesh can deliver the same network capacity, reliability and security that were once reserved for wired networks - but with the flexibility of wireless. With today's state-of-the-art solutions, municipalities, public safety agencies, port authorities, and industrial organizations can rely on mesh networks to provide essential connectivity to their workers and constituents. However, many technical issues still exist in this field. In order to provide a better understanding of the research challenges of WMNs, this article presents a detailed investigation of current state-of-the-art protocols and algorithms for WMNs. In this paper we propose MobiSEC, a complete security architecture that provides both access controls for mesh users and routers as well as a key distribution schemes that supports layer-2 encryption to ensure security and data confidentiality of all communications that occur in the WMN. |
