This paper analyzed some advantages and disadvantages of wireless sensor network protocols, and concluded the features of it. According to the features, the program members summarized its influence on the routing protocols, designed the models based on it and improved algorithms. They simulated the findings with OMNeT++, showing the rotation of cluster head can efficiently increase the lifetime of...
In this paper, we propose a node's call-for-assistant protocol, named an event-driven mobile assistant protocol (EDMAP for short), with which when a node N is going to exhaust its energy, it calls for mobile nodes to help it to relay packets so the tasks of sensing environment or environment change and relay packets for upstream nodes can be proceeded. Experimental results show that this approach...
