An efficient unscheduled communication for smart body centric networks

Applications of smart wearable devices to monitor human body functions are on the rise. In such networks, devices usually have limited resources. Therefore, energy efficiency is among the most crucial design issues. Efficient energy management strategies must be devised at device and network levels to prolong the network lifetime as much as possible. In a typical network, devices employ schedules to wakeup for communication. In this work, we present design and analysis of a protocol to reduce the energy consumption and delay. The proposed scheme manages the network by taking into account the device buffer capacity, packet drop probability and retry limits. It is observed that the proposed scheme is able to improve the performance in terms energy consumption and delay. We also present a comparative study with some of the state-of-the-art protocols.
