Due to increasing developments of medical science, early detection and receiving exact information in treatment of diseases and even preventing them are very important. Body Area Networks (BANs), a subset of Wireless Sensor Networks (WSNs), can deliver vital signs of patients to physician by collecting and analysis of patients' data and with applying different types of medical sensors. In this paper, a new link aware and energy efficient routing algorithm is introduced. In this algorithm, packets are divided into two categories: high-priority and low-priority packets and used for efficient next hop selection node. Selecting the next hop node based on the parameters such as the number of hops, delay and path loss is carried out. Results of simulation show that proposed algorithm improve average energy consumption and throughput compared to the similar routing algorithm.
