Aiming at energy limited problem of wireless sensor networks,this paper proposes an Energy Efficient and Balanced Data Gathering Protocol(EEBDGP).The protocol uses the Mobile Sink(MS) to collect data,it progressively relocates the MS closer to the regions that produce higher data rates and reduces transmission path of large data flow,enabling energy savings.When the data flow is even among the neighbors and the energy of MS's forward node is less than a threshold,MS moves to the adjacent node with the largest energy,enabling energy balancing.Experimental results show EEBDGP is energy efficient and energy balanced,it can prolong lifetime of networks greatly.
