通信网簇间的自适应路由算法

摘要

The navigation conditions of ships are quite complex, and cause huge power consumption when communication network operates, and often occur communication interruption. According to the characteristics of ship network communication between cluster, an adaptive routing optimization algorithm is put forward for the communication between network clusters, which ensures the best or second best route selection between the source node and the base station and also can reduce the sudden interruption of communications effectively when the network does not cover. Practical application show energy consumed is less after a round compared with other routing algorithm for cluster communication when throughput and BER is the same. Even when the node density is not the same, the network lifetime as well as continuing work time have been greatly extended.%船舶航行条件比较复杂，导致通信网络运行的功率消耗巨大，而且经常会发生通信中断的情况。针对船舶网络簇之间的通信特点，提出一种自适应的路由优化算法，可保证源节点和基站进行通信时能够选择最佳路由或次佳路由，有效减少由于网络没有覆盖到导致通信突然中断的情况。实际应用显示，文中所提的算法与其他算法相比，当吞吐量和误码率都相同时，经过一轮所消耗的能量更少，而且当节点密度不相同时，网络的生命周期以及网络的工作持续时间都被大大延长。
