D3: Data-centric Data D Wireless Sensor
نویسندگان
چکیده
This paper presents a novel method to disseminate sensor data in a wireless sensor network, called D3 (Data-centric Data Dissemination). The method combines the advantages of data-centric routing like SPIN and directed diffusion and energyefficient MAC protocols such as S-MAC and T-MAC. The protocol’s strengths are its energy-efficiency and its simplicity. Messages are transmitted using broadcasting only, reaching as many nodes as possible with the least energy. Furthermore, D3 easily accommodates energy-dependent traffic balancing and data aggregation, crucial to prolong the lifetime of a sensor network.
