Venue：Lecture Room 334, Level 3 Building #5

Abstract：
Energy consumption is a major concern in the deployment of wireless sensor networks (WSNs) due to the limited power supply in WSNs. In this talk I will show that applying mixed-routing and crona-devision strategies we can achieve balanced energy consumption and maximize network lifetime for data gathering WSNs of arbitrary topologies. First I will present stretagies to balance intra-crona energy consumption by applying zone-based partitioning within each crona, and inter-crona energy consmuption by setting a proper ratio of mixed routing for each crona, respectively. Then I will show how to maximize network lifetime by setting a proper number of cronas for the network and a proper sub-cronas within each crona. Finally I will describe an energy-balanced data gathering protocol and its extension to large-scale WSNs. Simulation results of our protocol in comparison with existing protocols (MEDGT, DT, LEACH) are also given.
