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...
Reliable data delivery is key problem in WSN. This article introduces network differentiated service, raises path_choose algorithm with differentiated service mechanism, which either adopt common data and periodically measuring data, or dispose exigent data. Commonly, source nodes select one non-intersectant path between clusters to deliver data depending on probability, low requirement to exigency;...
