A new data gathering protocol of Wireless Sensor Networks

This paper presented an idea of differentiated Service. Based on the idea, we designed a algorithm named DSDG which use differentiated service mechanism, it both use in-network data aggregation technology to efficiently collect data periodically and meet the requirement of urgent data processing. DSDG use differentiated service on network data flow, on the other hand, this algorithm use high efficient network data fusion technology on data transmission process. Simulate experiment indicate that comparing with LEACH and HEED, DSDG can make the WSN possess longer lifetime and better expansibility.
