Abstract

Recently, the interest in sensor network has increased with the advanced technologies in the field of digital signal processing, sensing and wireless networking devices. In this paper, an efficient protocol to set up a data dissemination path shared among multiple sink nodes is proposed for a special sensor network, where the source sensor nodes update their sensed data according to various desired update rates requested by sink nodes. We modify and enhance the basic SAFE(Sinks Accessing data From Environments) protocol to minimize the increased amount of data update rate at the intermediate nodes over a dissemination path. By using GloMoSim simulator, we show that our ESAFE (Enhanced SAFE) protocol outperforms the basic SAFE.
