Abstract

Wireless Sensor Network (WSN) is one of the emerging technologies in the 21st century due to its growing demand in automation. WSNs are organized in a large environmental area and there are more chances for the sensor nodes to get affected because of external temperature. As the environmental temperature rises, the lifetime, quality of service and temperature of sensor nodes are easily influenced. Thus Environmental Aware Thermal (EAT) routing protocol is introduced to minimize the issue. In this protocol, the incoming data signals are assigned with normal, abnormal and critical priority levels. It consists of three potential fields such as environment, energy and quality of service. The routing path is chosen in such a way that the critical data reaches its destination with minimum delay. Therefore, the path is selected depending on surrounding temperature, threshold level and residual energy. The network performance was analyzed in three different cases: 1, 2 and 3. The total amount of power consumption, temperature variation, delay and lifetime of sensor node in all three cases are inferred.
