RADIO TRANSCEIVER CONSUMPTION MODELING FOR MULTI-HOP WIRELESS SENSOR NETWORKS
Dan Tudose, Laura Gheorghe · 2013
Acest articol propune un nou model matematic pentru consumul de energie al emiţator-receptoarelor radio folosite in reţelele wireless de senzori. Aceste reţele sunt supuse unor constrângeri severe de consum de energie iar extinderea timpului de viaţa al nodurilor senzoriale alimentate din baterii este o cerinţa importanta care mareste autonomia reţelei. Primul pas pentru atingerea acestui ţel il constituie modelarea subsistemelor din cadrul unui nod senzorial unde energia este consumata. In cadrul acestui studiu, propunem un nou model matematic pentru estimarea consumului de energie a unui nod senzorial si evaluam parametrii acestuia atât pentru reţele tip single-hop cât si pentru cele multi-hop. This paper discusses a energy consumption model for radio transceivers in Wireless Sensor Networks. Wireless Sensor Networks are systems that are subjected to severe energy consumption constraints and extending sensor node battery life is a paramount requirement for network autonomy. A better understanding of where energy is spent in a typical wireless sensor node is a first step towards achieving this goal. We propose a model for estimating the energy consumption of a sensor node’s radio transceiver and evaluate its parameters for both single-hop and multihop wireless sensor network architectures.
