Wireless Mesh Networks have recently come out as a new networking technology for deploying wireless networking infrastructure in order to facilitate Internet access. Routing in WMNs is challenging because of the unpredictable variations in the wireless environments. In this book three multi path routing protocols namely AOMDV, MOLSR and MHRP are compared in terms of their performance in WMN. The book presents a balanced treatment of the theory, architecture and simulation of WMN.I hope it will prove beneficial to many readers.
