Buffered based routing and resiliency approach for WMN

Several approaches to effectively perform communication in Wireless Mesh Network (WMN) have been proposed. Further communication failures and possibilities of minimum services during such failures are very hard to maintain. Recently resilient multicasting and Resilient Opportunistic Mesh Routing for WMN (ROMER) approaches proposed routing and resilient methods over WMN. Resilient multicasting approach establishes two node disjoint path between each source-destination pair. But this approach can immune from any single link or intermediate node failure. While ROMER approach provides redundant copies of data in randomized manner to increase WMN throughput. We have proposed Buffer Based Routing method in which instead of maintaining routing table at each node we provide buffering at each node which reduces routing cost. At specific interval of time (after specified communication steps) it clears the buffer to increase performance and prevent overhead in network. Using this approach we effectively perform resiliency and exploits advantages o fWMN. The performance of the proposed approach is studied by evaluating the cost involved in routing and resiliency using these approaches and compared with the proposed approach.
