Abstract :
A dynamic multi-hop transmission method and its protocol are proposed to improve transmission quality and save radio resources in wireless ad hoc networks. By autonomously abbreviating hop path and enabling path-selection diversity between a shortcut path and normal two-hop path, transmission reliability improvement and reduction of unnecessary transmission are achieved. The enhancement method for current IEEE 802.11 MAC and AODV routing is presented to implement the proposed method. Packet success probability with this method is analyzed for Rayleigh faded wireless links. Simulation results show that the average packet delay in hop counts is also improved.
