【摘要】：本文针对无线传感执行网络(wireless sensor and actor network,WSAN),在昆虫生物种群协作机理的启发下,提出了一种WSAN协同方法,以改善网络传输可靠性、节能与执行效率.首先,针对传感器节点与执行器节点之间的协作,提出以信息传递能耗和剩余能量衡量中继节点选择概率的效能协同机制,以及包含区域中继、影响因子和学习因子3个保障单元的组织协同机制.进而,针对执行器--执行器间的协作,引入学习因子作为组织协同机制中的一个保障单元.最后,给出了算法执行的流程,并通过仿真验证了方法的优越性.仿真结果表明,采用本文提出的协同机制,不但优化了WSAN信息传递路径,而且在执行器节点间协作中选择优势节点参与信息处理和决策,降低了网络能耗,同时提高了网络执行效率.
[Abstract]:In this paper, a WSAN cooperative method is proposed to improve the reliability, energy saving and execution efficiency of wireless sensing execution network (wireless sensor and actor network,WSAN). Inspired by the cooperative mechanism of insect biological population, a WSAN cooperative method is proposed to improve the transmission reliability, energy saving and execution efficiency of the network. Firstly, aiming at the cooperation between sensor node and actuator node, an efficiency cooperation mechanism is proposed to measure the selection probability of relay node by information transmission energy consumption and residual energy, as well as an organizational cooperation mechanism which includes three guarantee units: regional relay, influence factor and learning factor. Furthermore, aiming at the cooperation between the actuator and the actuator, the learning factor is introduced as a guarantee unit in the organizational collaboration mechanism. Finally, the flow chart of algorithm execution is given, and the superiority of the method is verified by simulation. The simulation results show that the cooperative mechanism proposed in this paper not only optimizes the WSAN information transmission path, but also selects the dominant nodes to participate in information processing and decision-making in the cooperation between actuator nodes, which reduces the energy consumption of the network and improves the efficiency of network execution.
