多轨道大规模无线传感网络移动数据收集机制

摘要

针对无线传感器网络WSNs（Wireless Sensor Networks）能耗平衡问题，提出了一种多轨道大规模移动数据收集机制，简称为MTM（Multi-Track Mechanism）。MTM包括节点估计、能耗评估、多轨道能量平衡等3个阶段。通过使用MTM机制确定MS（Mobile Sink）的多轨道移动路线，可以优化整个WSNs的节点能耗。仿真表明，MTM是一种高效的数据收集机制，在节点能耗平衡、网络寿命延长方面有着突出的特点。%To pursue the energy-efficient features to maximum energy-balance at sensor nodes and prolong the network lifetime,this paper proposed an energy-efficient data collecting mechanism called MTM. The MTM mechanism is composed of three major phases,Such as Nodes Estimation Phase,Energy Estimation Phase,and Multi-track Energy-balance Phase. Through the use of MTM mechanism to determine the MS trajectory,the energy consume of the sensor nodes can be totally balanced. Theoretical analysis and performance simulation show that the proposed MTM mechanism has a prominent feature compared with the existing approaches in terms of the energy balance and network lifetime.
