A Low Energy Consumption Media Access Control Protocol for multi-level Body Networks using two Different Radio Channels

In this paper, a low energy consumption media access control protocol for multi-level body networks is proposed. In this protocol, we use a wake-up mechanism to reduce energy consumption of radio, so that the sensor nodes sense the patient's vital signs and the sink node sends data through an additional channel in order to receive the data of body vital signs and it starts sending the data after the wake up of sensor node. The sensor nodes send data to the sink node using IEEE 802.15.4 standard. The sink node is a device like a mobile device that receives data from nodes using IEEE 802.15.4 standard and sends it to a server's wireless access point after processing with IEEE 802.11 standard to be deployed on the local network or the Internet. The proposed method is simulated with Glomosim simulator and compared with the Leach method. Simulation results show the superiority of the proposed method.
