摘要
高效地使用资源和延长网络的生命周期是传感器网络中高效路由协议应考虑的很重要的问题。提出一种能解决以上两种问题的新算法,即在算法中使用双簇首,可以减少任何形式的流行算法的使用,因而节约了许多资源并且使得路由发现更容易。实验结果表明使用双簇首极大地减少了路由发现过程中的信息开销并且延长了网络的生命周期。
Efficient use of energy resources and prolonged lifetime of a network are very important issues to be considered for effective routing in sensor networks. In this paper a new algorithm is proposed which promises to deliver solutions to both the problems mentioned above, by using dual cluster head, which is very useful to minimize the use of epidemic algorithms of any sort, thereby saving a lot of resources and also making route discovery more easier. Simulations show that using dual cluster head greatly decreases the message overhead for route discovery and helps in extending the network lifetime.
