摘要
当前路由算法将光纤通信网络随机分为不同的簇,簇首能量较弱的点也有机会被选举为簇首,承担数据采集和传输功能,造成了节点坏死,该算法没有良好的躲避坏死节点策略,导致网络生存时间缩短,大大影响了光纤通信网络性能。提出一种基于蚁群优化算法的坏死节点躲避路由算法,在对LEACH协议分析的基础上,研究了一种光纤通信网络传输机制和能耗模型;采用蚁群优化算法进行簇首选取和多路径搜索,在蚂蚁搜索路径的过程中充分考虑链路传输能耗、链路剩余能量、通信传输距离、所选链路带宽和时延等因素,选取出能够躲避坏死节点的多条最优路径,实现数据传输。克服了当前算法没有良好躲避坏死节点策略的弊端。实验结果表明,所提算法能够有效平衡光纤通信网络中节点的能量负载,延长了网络生存时间,且能够实现坏死节点躲避,保证了数据传输性能。
The current routing algorithm randomly divides the fiber-optic communication network into different clusters. The points with weaker cluster head energy also have the opportunity to be elected as cluster heads and undertake data collection and transmission functions,resulting in node necrosis. The algorithm does not have a good strategy to avoid necrotic nodes. As a result,the network lifetime is shortened,which greatly affects the performance of the fiber-optic communication network. A necrotic node avoidance routing algorithm based on ant colony optimization algorithm is proposed. Based on the analysis of LEACH protocol,a transmission mechanism and energy consumption model of optical fiber communication network are studied. Ant colony optimization algorithm is used for cluster preferring and multipath searching. In the process of ant search path,fully consider the link transmission energy consumption,link residual energy,communication transmission distance,selected link bandwidth and delay,etc.,and select multiple optimal paths that can avoid necrotic node which achieves data transfer and overcomes the shortcomings of the current algorithm which has no good strategies to avoid necrotic nodes. The experimental results show that the proposed algorithm can effectively balance the energy load of nodes in the fiber-optic communication network,prolong the network survival time,and can achieve necrotic node avoidance and ensure data transmission performance.
