ABSTRACT
Wireless mesh networking has emerged as a promising concept to meet the challenges in next-generation wireless networks such as providing flexible, adaptive, and reconfigurable architecture while offering cost-effective solutions to service providers. Prior efforts on wireless networks, especially multi-hop ad hoc networks, have led to significant research contributions that range from fundamental results on theoretical capacity bounds to development of efficient routing and transport layer protocols. In a multi-hop wireless network, the source and destination nodes communicate in a multi-hop fashion. The bit error rate in wireless networks is very high compared to wireline networks. Many companies started research in wireless mesh networks on their own and in collaboration with academic research institutions. The wireless connectivity between routers significantly reduces the deployment and maintenance cost when compared with wired networks. In radio frequency transmission, when the transmitted signal is reflected by mountains or buildings the radio signal reaches the receiving antenna along two or more paths.
