Abstract
With the acceleration of the aging process of our country’s population and the rapid development of the urbanization process, chronic diseases have gradually become the main factor affecting the health of residents [1]. The emergence of wireless body area networks (WBANs) provides a simple and low-cost method for the health monitoring of patients with chronic diseases [2–4]. The efficient utilization of node energy resources is the key to the practical application of WBANs. In this paper, we propose a collaborative routing algorithm based on data priority. The algorithm allocates the maximum number of hops for this data transmission according to the priority of the data transmission, and then finds transmission path which consumes minimum energy resource. So as to achieve efficient utilization of energy resources. Finally, through the simulation of the maximum number of hops obtained by the priority of the transmitted data, it is concluded that a fixed node with multiple maximum number of hops has a longer life time.
