Sensing and transmission phenomena of an implanted sensor dissipates energy which results in rise in temperature of its surroundings. Simultaneous operation of such multiple active sensors increases the temperature of the surrounding environment causing hotspots. Such hotspots are highly undesirable as they may cause damage to the environment as well as to the sensor network, posing a challenge for deployment of sensors. The problem is further enhanced for a temperature sensitive environment, as the allowable threshold temperature for such environments is less. Here authors investigate the formation of hotspots in such temperature sensitive environments due to the heat dissipation of multiple active sensors and try to achieve a maximum coverage of such networks avoiding hotspots.
