Method of limiting the emissivity of WSN networks

Abstract

Wireless sensor networks (WSNs) are a current topic of research that find usage in many applications fromenvironmental monitoring and health protection to military applications. In this paper, analysis of the possibility ofreducing the emissivity of radio sensor networks with the assumed transmission probability is discussed. This has a directinfluence on power consumption by the nodes and network lifetime. A method based on introducing retransmissionson individual links creating paths between the nodes is presented. Two approaches are used in analyses, the first onebeing deterministic methods and the second one simulation. Both methods are used to determine the emissivity of thenetwork. The obtained results are compared with a method that uses retransmission on entire paths. This shows thatemissivity is more than five times less than the values obtained by retransmission on entire paths.
