【摘要】：已有研究显示,可充电型无线传感器网络(RWSN)为解决传统网络中节点能耗不均衡等问题提供了新的思路。为了在移动充电器(MC)个数有限的情况下均衡网络中节点的剩余能量,提高网络的性能。提出了一种基于移动数据收集和移动充电相结合的全网能量均衡机制Ms Mc EBP。Ms Mc EBP包括2个部分,即移动充电策略MCS和移动数据收集策略MDCS。在Ms Mc EBP中,首先将整个网络划分为若干个子区域,然后为每一个子区域分配一个MC。MC不仅担任充电器,还担任数据收集器。MCS旨在为网络中能量消耗较高的节点进行能量补充并且由MC收集各个区域的数据。MDCS旨在解决Sink如何从MC处收集数据。最后,对Ms Mc EBP进行了模拟仿真。仿真结果表明,Ms Mc EBP具有较好的性能,在网络寿命结束时,网络中所有节点的剩余能量都趋近于0。并且在数据精确度要求不高的情况下,Ms Mc EBP可以实现网络的永久运作。
[Abstract]:It has been shown that the rechargeable wireless sensor networks (RWSNs) provide a new way of thinking to solve the problem of unbalanced energy consumption of nodes in traditional networks. In order to balance the residual energy of nodes in the network with the limited number of mobile chargers, the performance of the network can be improved. An all-network energy equalization mechanism Ms MC EBP.Ms MC EBP based on mobile data collection and mobile charging is proposed, which consists of two parts: mobile charging strategy (MCS) and mobile data collection strategy (MDCS). In Ms MC EBP, the whole network is first divided into several sub-regions, and then a MC.MC is assigned to each sub-area to act not only as a charger, but also as a charger. It also serves as a data collector. MCS is designed to replenish energy for nodes with high energy consumption in the network and the MC collects data from each region. MDCS aims to solve how Sink collects data from MC. Finally, the simulation of Ms MC EBP is carried out. The simulation results show that Ms MC EBP has good performance. At the end of network life, the residual energy of all nodes in the network approaches 0. Furthermore, Ms MC EBP can realize the permanent operation of the network under the condition of low data precision.
