摘要
面对无线传感网络(wireless sensor network,WSN)路由问题,提出新颖生物激励-自我组织的安全自适应路由协议(biological inspired self-organized secure autonomous routing protocol,BIOSARP)。BIOSARP采用改进蚁群优化算法(improved ant colony optimization,IACO),利用端到端传输时延、剩余电量和链路质量计算信息素,并据此信息决策最优转发节点,从而减小广播次数和数据包负担,降低时延、数据包丢失率和功率消耗。仿真结果表明:提出的BIOSARP在数据包传递率、能量消耗优于安全实时负荷分配协议(secure real-time load distribution,SRTLD),数据包传递率提高24.75%,能量消耗降低31.8%。
To solve routing problems in wireless sensor networks(WSN),a biological inspired self-organized secure autonomous routing protocol(BIOSARP) has been proposed in this paper. In the BIOSARP mechanism, an optimal forwarding decision was obtained by the improved ant colony optimization(IACO). With the help of the IACO,the pheromone value was computed according to the end-to-end delay,remaining battery power,and link quality metrics. The proposed BIOSARP has been designed to reduce the broadcast and packet overhead to minimize the delay, packet loss, and power consumption in WSNs. Simulation results show that the delivery ratio of the BIOSARP has been improved by 24.75% so as to reduce the energy consumption by 31.8%compared to the secure real-time load distribution(SRTLD).
