To address the problem of temporary communication blindness caused by traditional beacon exchange in mobile senor networks

a novel adaptive beacon exchange algorithm is proposed on the basis of the characteristics analysis of the link.The working node calculates variable beacon change period according to different link broken probability

and the idle node selects the beacon change period by the distribution of link lifetime.Simulation results demonstrate that the proposed algorithm effectively reduces the phenomenon of temporary communication blindness and greatly improves the performance in terms of transmission success rate and consumption.
