Design and implementation of sequential repair and backup routing protocol for wireless mesh network

The applications of wireless mesh network in the embedded systems have become more widely. It´s an important issue that how to consume lower energy and transfer data stably based on energy considerations. A routing protocol is proposed with sequential repair and backup routing protocol (Ad Hoc On-Demand Distance Vector Routing-Sequential Repair and Backup Routing Protocol, AODV-SRBR Protocol), that can reduce the number of transceivers and have a stable connection. In the proposed routing protocol, the node of network can create multi-route message through decoding the path information of packets. When the link is broken, the proposed protocol can repair the data transmission by sequential repair or select backup routing. This study implements the routing protocol to verify a multi-hop connection and data transfer in the general environment. The performance of AODV-SRBR and AODV is compared and simulated by NS2. The proposed routing protocol can achieve same transmission efficiency in the fewer route request packets; fewer maintained packets and fewer transmit and receive times according to the simulation result. By stable connection, low power consumption and multi-hop data transfer, this work expects that the proposed routing protocol on the embedded systems platform can be extended in large sensor mesh network.
