Reliable Data Delivery Algorithm Based on Differentiated Service in WSNs
Xinlian Zhou, Wang Run-yun · 2009
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; once emergencies, insure exigent data correctly arriving Sink, and meantime start up all non-intersectant paths to enhance reliability. Simulated experiment indicates, although it increases slightly energy consumption, obtains higher data reliability than approved LEACH.
