摘要
针对无线传感器网络的能耗问题,提出了一种基于蚁群算法的路由协议,在簇首选择时考虑到节点的剩余能量,确定节点的实际通信半径,成簇时采用预测机制,簇间采用蚁群算法构建多跳路由。在OMNET++环境下进行实验表明:该协议可有效延缓节点死亡时间,延长网络生存周期。
Aiming at the energy consumption of wireless sensor networks, the paper presents a routing protocol based on ant colony al- gorithm, takes into account the residual energy of nodes in the cluster head selection, delcrmine the node communication radius of clusters, uses predictive mechanism to form clusters, and uses ant colony algorithm to construct multi-hop routing among the clusters. The experiments show that on OMNET ＋＋ environment： the protocol can effectively delay the node time of death, prolong the network lifetime.
