A High Performance Target Tracing Transmission Model Oriented to Lifecycle Maximization

For the high speed sensor networks applications such as internet of things,multimedia transmission,the realization of high-rate transmission under limited resources has become a problem to be solved. a high speed transmission and energy optimization model oriented to lifecycle maximization is proposed in this paper. based on information-directed mechanism,the energy threshold set and the relay node distance selection will be done in the process of target tracing,as a result,retaining a balance between transmission rate and energy consumption. meanwhile,multiagent coevolution is adopted to achieve the maximum of network lifecycle. comparing with the relevant methods,indexes for network such as hops,throughput,and number of active nodes,standard deviation of remaining energy,and the network lifecycle are considered,and the simulated experiments show that the proposed method will promote the transmission rate effectively,prolong the network lifecycle,and improve network performance as a whole. © 2016 zhong-nan zhao et al.
