Wireless Mesh Network Routing Protocol Challenges -Traffic Engineering Solution

Wireless Mesh Network (WMN) is an evolving heterogeneous standard for multi-radio, multi-hop and multi-channel network technology. It has numerous potential, commercial advantages and is currently undergoing rapid research development and standardization. The growing need for adaptive and scalable routing protocol for heterogeneous mesh multi-hop network has enabled research into different areas of solutions. The high demand on the routing protocol for real-time multimedia traffics applications with its resultant high packet traffic, coupled with the inherent interference and scalability issues creates the need for a reliable routing protocol. In this paper, we studied the current solutions migration with more study emphasis on traffic engineering adaptation to Wireless mesh network routing protocol. This paper introduces a potential research opportunity in traffic engineering as a solution for path diversity, scalability, quality of service and security in WMN routing protocols
