Due to increasing developments of medical science, early detection and receiving exact information in treatment of diseases and preventing them are very important. Body Area Networks (BANs), a subset of Wireless Sensor Networks (WSNs), deliver vital signs of patients to physician by collecting data applying different types of medical sensors. One of the most significant challenges faced, is the design of a link aware routing algorithm with different data priority. In this paper, a new link aware and energy efficient routing algorithm is proposed to select the efficient next hop node for the packets. Next hop node selection is based on the type of the packets. Results of simulation show that the proposed algorithm improves energy consumption, path loss and throughput compared to the similar routing algorithm.
