Research of reliable routing in wireless Ad Hoc network
无线Ad Hoc网络中可靠路由的研究

First, the Expected Transmission Count (ETX) algorithm was improved, and the new link status monitoring algorithm of combining the dynamic ACK algorithm and the improved ETX algorithm was presented, which could ignore the bad link in routing path. Then a new backup routing mechanism was proposed to replace the previously mentioned backup routing mechanism of QDSR. Route recovering could be initiated from middle nodes on the disjoined path, therefore, the route recovery could be done fast. NS2 simulation results demonstrate that the improved algorithm significantly reduce the routing error, and greatly reduce the average time to find a new path after the disjoined path in a large scale MANET of the node while at smaller moving speed.
