摘要
无线传感器网络的发展催化出了很多不同类型的能量高效型路由协议,但却几乎都将焦点放在节点分布和节点组织上,但实际的应用中对能量和连通可靠性需求决定了WSN架构应通过多种途径来完善。其中关于基站的最优化分布和多基站协作运算尤为重要。针对多基站协作的课题展开研究,提出一种多基站协作模型(MBCM)。该算法量化地给出了MBCM中影响网络生存因素的量化指标,并利用M-tree来组织网络结构和最小化网络传输代价。仿真结果与理论分析一致验证了该算法为网络提供了更强的生存能力,与单基站的网络相比较,多基站网络可以延长57%的网络寿命。
Recent development wireless sensor network（WSN） has lead to the emergence of many application oriented protocol which must be energy efficiency. However, most of them are focus on the nodes＇ distribution and organization, but the fact is the high - level requirement of energy efficiency and connective reliability in practical application decides that the architecture of WSN should be considered in through a variety of ways. Among them, the methods that linked to the basestation location and multi - basestation cooperation are crucial. In this paper,study on the issue of multi - basement cooperation and propose a multi - basestation cooperating model based on M - tree（MBCM）. The algorithm quantify the influencing factors which impact the network＇s survival times, what＇s more, MBCM rises the M- tree structure to organize the network architecture and minimize the network transmission costs. The simulation results and the theoretical analysis shot＇s that the MBCM provides a stronger survivability, compared to the single base station network, the lifetime is extended in about 57%.
