Data dissemination protocol for mobile sink group in wireless sensor networks
Hu Donghui · Journal of Hefei University of Technology · 2013
In wireless sensor network(WSN),when a number of sinks staying closely move together,the existing routing protocols require every sink to update its location to the source.As a result,the routing overhead becomes too high.To solve this problem,a data transmission protocol based on mobile sink group,i.e.the leader of group location updating method,is proposed to reduce the routing overhead and economize the energy consumption of the network.The simulation results indicate that the proposed protocol not only guarantees the success delivery ratio of data packets,but also reduces the energy consumption of the network and prolongs the lifetime of the network.
