摘要
该文提出在无线传感器网络中基于移动代理的自适应数据融合路由(AFMR)算法,解决移动代理如何以能量有效的方式融合、收集相关性数据的问题。该算法综合考虑了移动代理在路由过程中传输能量和融合能量的消耗,并根据数据融合算法的能量开销和节能增益,对移动代理迁移到各节点时是否执行数据融合操作进行自适应调整,以达到在各种不同的应用场景中优化移动代理能量开销的目的。通过仿真验证了在无线传感器网络的各种相关性数据收集的应用环境中,AFMR算法在节省能量方面比现有TSP和FMR的移动代理路由算法更加有效。
in this paper, an energy efficient Adaptive Fusion Mobile-agent-based Routing algorithm (AFMR) is presented in Wireless Sensor Networks (WSN), where AFMR can provide energy efficient Mobile Agent (MA) routing algorithm for correlated data gathering. AFMR is used to not only jointly optimize over the costs for both data transmission and data fusion, but also evaluate the cost and benefit of the data fusion, in order to adaptively adjust whether fusion shall be performed for minimizing the total energy consumption when MA migrates to a particular node. Simulation results show that AFMR achieves better performance than existing MA routing algorithm including TSP and FMR from perspectives of energy consumption in a variety of correlated data gathering applications.
