摘　　要：目的研究并提出多向多sink无线传感器网络路由算法,实现多sink节点数据传输。方法在对多向多sink网络拓扑结构分析的基础上,根据数据多向传输的要求,研究基于相遇蚁群算法和精英策略的多向多sink WSN路由算法。结果提出了一种采用相遇蚁群算法和精英策略相结合的WSN路由算法,并对算法进行了分析和仿真。结论仿真结果表明,该算法可以实现同一个传感器节点数据传送到不同的sink节点,其效率和收敛时间明显优于GEM和GBR算法。Aim To achieve a routing algorithm for multi-sink node and multi-direction wireless sensor networks （WSN） to satisfy the needs of multi-direction data transmission. Methods Based on the analysis on the characteristics by topologies and transmission needs of multi-sink node wireless sensor networks, a routing algorithm was established based on Meeting Ant Colony optimization. Results A multi-direction routing algorithm based on Meeting Ant Colony optimization for multi-sink node wireless sensor networks was achieved. Conclusion The simulation proved that this routing algorithm can transfer the data to different sink nodes in different directions. Its efficiency and convergence are significantly better than GEM and GBR.
