An energy-efficient multi-hop routing protocol for health monitoring in wireless body area networks

摘要

Wireless Body Area Network (WBAN) is an emerging field in computer technology, that plays vital role in society, which facilitates the medical practitioners to remotely monitor and allows them to provide accurate treatment to patients. In WBAN, routing plays an important role to prolong the life time of WBAN. Routing establishes the path between wireless sensor nodes and sink node. In this paper, we propose a protocol in WBAN which transfers body sensing data from various sensors, deployed on human body, to sink node using multi-hop routing technique. The main objective of our approach is to prolong the average network life time of WBAN by reducing overall energy consumption. In our approach, we select a parent node in a multi-hop, based on residual energy, using Mamdani (Fuzzy logic) approach. We show the efficacy of our approach using simulations. We also compare our approach with two state-of-art routing algorithms viz. SIMPLE and M-ATTEMPT.
