层次模型的移动传感器网络路由算法

Hierarchical Model Routing Algorithm for Mobile Wireless Sensor Network

路由算法是无线传感器网络的关键问题之一,但在移动无线传感器网络中,由于拓扑动态变化,使得传统的网络路由算法都很难较好地应用于移动网络环境,同时也为设计好的路由算法带来巨大挑战.文章提出移动传感器网络层次模型路由算法.仿真结果表明,应用该算法能够有效提高网络数据转发率、增加网络吞吐量和网络综合性能,且性能要优于LEACH和DT算法.

The routing is one of important problem in mWSN because routing algorithms plays a great role during the whole period of networks. However, as mWSN topological dynamics, which bring more difficulties to design a good route algorithm. In this paper, we put forward a algorithm, the hierarchical model routing algorithm for mobile wireless sensor network（HMRA）, to increase data forwarding rate, network throughput and overall performance for mWSN. The simulation results clearly show that HMRA has a better performance in terms of packet forwarding rate, network load, network throughput than LEACH and DT.
