Abstract To solve the problem of time-variant communication links in Wireless Body Area Networks (WBANs), a novel energy efficient and reliable Adaptive Routing (AR) protocol is proposed. Based on the analysis of data propagation model, a computing method for the quality of outer links, which are trained by Hidden Markov Model (HMM) as the observation value in order to find the optimal routing path, is also brought forward. The simulation results indicate that compared to the existed prediction-based routing protocol such as Prediction-based Secure and Reliable routing framework (PSR), etc., the performances such as the network packets loss rate, the network time delay and the nodes’ lifetime are improved significantly in the proposed.
