Hybrid Hierarchical Fuzzy Inference System to Improve Network Lifetime of WBANs for Health Monitoring

Wireless Body Area Network (WBAN) is a new area of computer technology that allows doctors to monitor patients remotely and provide appropriate treatment. Routing is important in WBAN because it prolongs the life of the network. Routing creates connections between and sink. In this paper, we present a protocol in WBAN that uses multi-hop routing to send body sensor data from multiple nodes placed on the human body to a single Sink. The main aim of our method is to increase the lifetime by reducing the total energy consumption. We use Hybrid Hierarchical Fuzzy Inference System(H2FIS) technique to select a relay node in a multi-hop network based on alive nodes, distance, and residual energy. Using simulation, we demonstrate the effectiveness of our strategy. We also compare our method with three modern routing algorithms, RSSI, SIMPLE and M-ATTEMPT gives more network lifetime.
