Abstract

Energy efficiency is a key issue for outdoor Wireless Body Area Networks (WBANs) that wireless sensor operates near or in human body. WBAN suffered from major problem of energy consumption. As a result, in outdoor simulation based on ZigBee S1 pro type used as transmit and receiver model. The investigation has been carried out based on channel propagation characteristic of what used in simulation based on ZigBee network with multiple sensing nodes, and the design can calculate the channel characteristic such as received power, path loss, path loss free space and path gain. The simulation enables to choose best route to reduce energy consumption depending on the values that have been obtained. Simulation has two routes to using multi point rout to transmit the data from patient nodes to the hospital.
