| Abstract: | This paper analyzes and compares several typical existing data gathering protocols, and according to the actual application needs, designs a new data gathering protocol of Wireless Sensor Network(WSN)——Differentiated Service and Data Aggregation(DSDA). By constructing an agreement constitutes effective cluster-tree network topology, using differentiated service for the network data flow, and using network data aggregation technology for the data transmission process, DSDA improves the existing data gathering protocols. Simulation results with Matlab show that DSDA can reduce the overall energy dissipated in the network and prolong the network lifetime. |
