摘要
以无线传感执行网络为对象,借鉴生物免疫机制,以能量高效、任务高效协作为目标,首先建立无线传感执行网络协同问题与生物免疫机制的类比模型,进而分别针对传感器—执行器协同及执行器—执行器协同问题,提出基于生物免疫机制的传感器—执行器自适应路由协同算法,及执行器—执行器任务协同算法,并给出算法执行流程。最后,通过仿真验证了方法的有效性与优越性。仿真结果表明,采用所提出的协同方法,不但优化了WSAN信息传递路径,而且降低了网络能耗,同时改善了能量均衡指标。
Taking the wireless sensor and actuator networks as the object, the biological immune mechanism as the reference, and the energy efficiency and efficient task collaboration as the purpose, in this paper we first build the analogy model of the wireless sensor and actuator networks problem in contrast with biological immune mechanism, then further present the biological immune mechanism-based adaptive sensor-actuator routing collaboration algorithm for the collaborations of sensor-actuator and actuator-actuator problems respectively, as well as give the implementation process of the algorithm. Finally the effectiveness and advantage of the proposed method are validated through simulation. Simulation results show that to employ the collaboration method proposed can optimise the information transmission path in WSAN, and can reduce networks energy cost as well, besides, the energy equilibrium index is improved too.
