Social Network-based Data Delivery for Delay Tolerant Mobile Sensor Networks
The delay tolerant mobile sensor network is a type of sensor network,which is used for data gathering.In this paper,a novel data gathering method named social network-based data delivery scheme(SNBD) is proposed.SNBD introduces interaction strength and assortative mechanism.The value of two nodes interaction strength and assortative is calculated which is used for choosing the next hop.In order to optimize node queue,SNBD employs importance factor parameter and TTL to decide message′s transmission and dropping for minimizing transmission overhead.Simulation results have shown that the proposed SNBD data delivery scheme does not only achieve eight times as much long network lifetime as SRAD and FAD,but also get the higher message delivery ratio with lower transmission overhead and data delivery delay than SRAD and FAD.
