MAC protocol based on adaptive update in wireless senor networks
Guang Chen · Journal of Computer Applications · 2012
In order to solve the energy limitation problem on wireless sensor network nodes,this paper proposed a new adaptive update asynchronous MAC protocol — AU-MAC protocol.This protocol combined the sleep-work state switching mode,asynchronous mode with adaptive update to effectively extend the network life.AU-MAC protocol improved channel usage efficiency by making use of sender monitoring and receiver activating data transfer.And,it established a neighbor node information table and introduced adaptive updating mechanism,to reduce the free monitor.The functions of AU-MAC protocol had been estimated on NS2 network simulation platform.It shows that,AU-MAC protocol improves the energy efficiency at the basis of maintaining the same throughput and end-end transit delay.
