A Route Discovery Scheme of Clustering Ad Hoc under Network Scenario
GE Wen-ha · Computer Technology and Development · 2015
A scheme of reactive route discovery is proposed based on RSSI and neighbor priori- knowledge,aiming at routing problem of the clustering Ad Hoc scenario. Based on cluster network feature,this scheme considers the RSSI between nodes and traffic- load of relay nodes during RREQ broadcast,and introduces the delay back- off forwarding mechanism to comprehensively determine whether to forward RREQ packet,solving the routing overhead problem caused by broadcast storm and optimizing performance of route discovery. Simulation results show that compared with performance of protocol CBRP,the scheme significantly reduces the route discovery control overhead and shortens the discovery delay,improving overall network performance.
