Temperature-Aware Routing Using Secondary Sink in Wireless Body Area Sensor Network

Wireless Body Area Sensor Network (WBASN) is a developing application of Wireless Sensor Network (WSN) which is very useful in diagnosis of human health remotely. Tiny and smart sensors are placed inside or outside of human body which collects useful data time to time from various parts of body and send it to the corresponding medical staff or doctor. In the future, WBASN will surely make a huge change in traditional health monitoring system and will be helpful for elderly people and patients who suffer from difficult physical mobility. WBASN have many challenges while its design and one of main challenge is controlling temperature rise of sensor node during routing when placed inside human body because temperature rise beyond certain limit will be harmful for human body. The study of controlling temperature rise of sensor nodes during data routing comes under the category of Temperature Aware Routing Protocols. In this article the authors have raised a problem called “Energy Hole Problem” under Temperature Aware Routing Protocols which affects the performance of a network.
