Aiming at problem that temporary communication blindness caused by greedy geographical routing protocol adopts stationary beacon exchange in mobile wireless sensor networks（ WSNs）

a novel adaptive beacon exchange algorithm is proposed. The algorithm adopts node moving speed

node residual energy

number of neighboring nodes as evaluation factors and confirm adaptive beacon period using fuzzy logic control mechanism.The adaptive beacon exchange algorithm can increase accuracy and realtime of neighbors table construction and maintenance and provide reliable basis for greedy geographical relay. Simulation shows that the proposed algorithm reduce phenomenon of temporary communication blindness

increases packet delivery ratio and reduce average end-to-end delay as well as control overhead

so it is suitable for application of large-scale mobile WSNs

which has high requirement for transmission reliability.
