Architecture, issues and challenges of wireless mesh network

Wireless Mesh Network has the ability to provide broadband access dynamically to anyone anywhere in the world by setting up nodes in the network. It provides the wide scale connectivity with less cost than the wired network. In addition to the cost advantage, wireless mesh networks (WMNs) are easy to sustain, robust and provide reliable service coverage. Wireless mesh networks (WMN) are multi-hop networks with the capability of sending packets between wireless routers. In this paper the architecture, features and applications of distinct wireless mesh networks has been described. In addition, during communication in wireless mesh networks the purpose and performance of various layers has been described. Number of issues and challenges are raised in WMN because of its performance. In this paper, we have specified the challenges and issues in this emerging technology that have to be solved in order to have an efficient and reliable communication.
