An Energy Consumption Model for Time Hopping IR-UWB Wireless Body Sensor Networks

In this paper, we focused on the energy consumption model of Wireless Body Sensor Networks (WBSN), where sensors can be deployed in various part of a human body. Since energy limitation is one of the biggest challenging issues in sensor network, it becomes more crucial for some special devices if those are used inside the body and then become impossible to replace frequently. In such a case, we must need to increase the lifetime of a sensor node. We proposed a Time Hopping Impulse Radio Ultra Wide Band (TH IR-UWB) energy consumption model for sensor nodes along with the slotted sleeping protocol. Simulation results showed that energy consumption per bit was very low and therefore this energy model was useful to increases the lifetime of WBSN.
