无线传感器网络是一种自组织网络,其自组织性以及节点能量受限的特点,使得如何设计路由协议以达到既保证数据传输的完整性又最大限度延长网络寿命变得至关重要。该文提出了一种新的路由机制来延长网络寿命,适合于静态的网络。最后通过模拟仿真说明了改进的路由协议比LEACH协议在延长网络寿命上有很大的改进。
Wireless sensor networks are a kind of self-organizing networks, which determine a number of drawbacks: topological and limited node energy. So how to design a routing protocol which is to ensure the in- tegrity of data transmission and energy balance of the network to maximize the life of the extension of the net- work is essential. This paper presents a new routing mechanism to extend the network lifetime. Compared with routing protocol LEACH, the new methods select cluster heads by random, but the choice can balance the net- work energy and prolong the life of the network. The simulation results also illustrate the improved routing pro- tocol is greatly improved than the LEACH protocol in extending the network lifetime.
