An Energy-Efficient Data Gathering Algorithm(EEDGA) is proposed for monitoring events in a kind of reactive Wireless Sensor Networks(WSNs).First,EEDGA selects a clusterhead according to the correlation and residual energy among the nodes located in the event area.Then,EEDGA utilizes ant colony algorithm to form a chain of data gathering inside the cluster.EEDGA also proposes a simple method to reduce the energy consumption by choosing active nodes according to the demand of measuring accuracy.Simulation results show that the proposed EEDGA can achieve higher energy efficiency and longer network lifetime than that of the traditional routing algorithm.
