摘　　要：为解决无线传感器网络(WSN)中节点部署不均匀造成的节点能量消耗大、数据传输可靠性低的问题,提出了一种基于免疫连通模型的多路径传输选择算法。当数据传输发生故障时,免疫机制被用来选择路径的适应度函数,从而达到优化传输路径和减少节点能耗的目的。实验从网络寿命、端到端传输延迟、覆盖率、传输可靠性、载荷分布等指标对算法进行评价。实验结果显示,所提算法可更好地平衡负载,延长网络的生命周期,以及保证数据传输的可靠性。所提算法可以应用于对能量效率、可扩展性、延长网络寿命和降低网络开销有较高要求的传感器网络设计。In order to solve the problems of high node energy consumption and low data transmission reliability caused by the uneven node deployment in Wireless Sensor Network(WSN),a multipath transmission selection algorithm based on immune connectivity model was proposed.When data transmission failed,the immune mechanism was used to select the fitness functions of paths,so as to optimize the transmission path and reduce the energy consumption of nodes.The experiments were performed to evaluate the proposed algorithm by the indicators such as network lifetime,end-to-end transmission delay,coverage ratio,transmission reliability and load distribution.The experimental results show that the proposed algorithm can better balance the load,improve the life cycle of network,and ensure the reliability of data transmission.The proposed algorithm can be applied to the design of sensor networks with high requirements on energy efficiency,scalability,prolonging network life and reducing network overhead.
