Abstract
This paper proposes an efficient event delivery algorithm called distributed group mobility adaptive event delivery(GMED) for delay tolerant mobile sensor networks(DTMSN).GMED is designed to establish a group-based event delivery model by effectively finding and utilizing the groups generated by moving sensor nodes which then lead an improved performance: On one hand,Inter-Group delivery will be achieved by multi-replica delivery based on its delivery probability to the sink.On the other hand,Intra-Group delivery will be performed by single-replica delivery through established transmission paths because each node have stable neighbor sets inside group.Meanwhile,delivery prioritizing will be based on event priority in the queue.Furthermore,a redundant replica control mechanism is also introduced to optimize replica management and network overload.Simulation results have shown that GMED not only achieves a relatively long network lifetime,but also has a higher message delivery ratio at lower transmission overhead and delay than other DTMSN data delivering approaches.
