TEARP: New Temperature and Energy Aware Routing Protocol for Wireless Body Area Network (WBAN)

Abstract

In the near future, the biomedical research will be one of the major applications for sensor networks. Wireless Body Area Networks (WBANs) consist of a set of bio-sensors that are implanted inside the human body to sense several health conditions, the communication between these sensors is made wirelessly. These sensors are charged by a battery. The nodes will transmit the sensed data through other nodes in the order it to the base station which is located outside the sensing environment which in this case represents the human body. The communication field consumed a significant amount of node’s energy and minimizes the lifetime of the node. Furthermore, the sensor’s operation generates heat which raises the tissue temperature around the implanted sensors. Therefore, the research majorly addresses these issues of communication, a new Temperature and Energy-Aware Routing Protocol (TEARP) has been presented for WBANs implementing a new route-choice system that seeks to equalize the use of energy of sensors and minimize their overheating. This method is depending on a formula that takes into account the remaining energy of sensor nodes, the distance between nodes as well as between nodes to sink, in addition to their temperature when selecting the following relay node. The simulation results show that the TEARP protocol has improved network lifetime efficiency by about 300%and 90%, stability by about 82% and 11%, and residual energy by about 71% and 74% compared to the M-ATTEMPT and Simple protocols respectively.
