A novel collaboration and communication decision based on multi-agent in wireless sensor network

Sensor nodes must work together to complete the task of WSN. Multi-agent and WSN have similar characteristics, so the theory of multi-agent has become the main methods to resolve WSN collaborative problems. First of all, in the paper WSN collaboration based on multi-agent is analyzed, and then the communication decision based on multi-agent is studied. In order to reduce the complexity of implementation of multi-agent collaboration strategy using the POMDP models, and decrease the amount of collaborative communication, a heuristic algorithm is presented. And communication is chosen only when an agent´s observations indicate that the information will improve team´s expected reward. The experimental results show that the presented approach can reduce communication, efficiently utilize communication bandwidth, and help improve system performance.
