| 摘 要： | 为了解决PEGASIS协议使网络容易陷入局部最优而所形成的链路较长的弊端,提出一种有效的基于PEGASIS协议的路径优化方法对链路进行优化,得到更短的全局最优路径,有效减少网络通讯距离.最后使用matlab进行验证,将其验证结果与PEGASIS协议进行比较,基于PEGASIS协议的路径优化方法能提高网络的生存周期,平衡各节点的能量消耗.

An path-optimization method based on the PEGASIS protocol |
| |
| Abstract: | In order to solve the weakness of the PEGASIS protocol which makes the network easily trapped in a local optimum condition,an efficient path-optimization method base on the PEGASIS protocol is proposed to optimize the link and get a shorter global optimal path to reduce the network communication. Finally the algorithm using the matlab simulation has proved that compared with the exiting PEGASIS protocol,the new algorithm can improve the life cycle of the network,and balance the node energy consumption. |
