传感器、执行器和网络设备(SADN)是由三种类型的节点,传感器、执行机构,驱动设备节点。传感器节点和执行器节点在无线网络互联中讨论无线传感器和致动器网络(WSANs)。执行器节点和设备节点类型的网络互连,即无线和有线网络。传感器节点一个物理事件和感觉到的事件值发送给执行器节点。一个执行器节点作出决定适当的行动收到感觉值,然后问题行动请求设备节点。设备节点真的对现实世界的行为。例如,移动机器人手臂进行操作的行动在收到请求。消息可能会丢失,节点可能是错误的。尤其是消息丢失由于噪声和碰撞在一个无线网络。我们提出一个完全冗余模型的SADN每个传感器、传动装置和设备功能复制到多个节点,一般和actuator-device沟通是实现多对多的通信协议类型。 Even if some number of nodes are faulty, the other nodes can perform requested tasks. Here, each sensor node sends sensed values to multiple actuator nodes and each actuator node receives sensed values from multiple sensor nodes. While multiple actuator nodes communicate with multiple replica nodes of a device. Even if messages are lost and some number of nodes are faulty, device nodes can surely receive action requests required for sensed values and the actions are performed. In this paper, we discuss a type of semi-passive coordination (SPC) protocol of multiple actuator nodes for multiple sensor nodes. We discuss a type of active coordination protocol for multiple actuator nodes and multiple actuation device nodes. We evaluate the SPC protocol for the sensor-actuator coordination in terms of the number of messages exchanged among actuators.
