Ruchuan Wang · Dianzi xuebao · 2007
Wireless sensor network is a novel technology,and can be applied to both abominable and military environments.During gathering the data,wireless sensor network should decrease the power costs of redundancy information and delay time.The technology of data aggregation can be adopted.A tree formation algorithm for data aggregation based on estimate cost is presented.The paper applies directed transmission model and message route mechanism.The idea of this algorithm is optimization of data aggregation route by estimate cost about energy,distant and aggregation gain,then realizes data aggregation trade-off in energy and delay.
