Scheduling to Increase Lifetime for Low Energy Body-Centric Wearable Networks
                        draft-hongcs-6lo-sbcn-00

Abstract

Recent advances in Internet of Things(IoT) have increased the usage of 
sensing technologies. Breakthroughs is microelectronics have increased the 
use of wearable devices to monitor human body functions and its surroundings. 
A typical wearable device has low resources in terms of power and processing 
capabilities. Reducing the energy consumption is one of the key design factors 
in a wearable network so that the devices may work for longer duration. Idle 
listening and overhearing are major causes of energy consumption. These issues 
can be resolved by maximizing the sleeping time of a device (switched off) and avoid 
unnecessary wakeup time (idle listening) to save energy. An external wakeup 
scheduling to handle the sleep/wakeup cycle of a device can be adapted. 
This document describes how a 2wakeup scheduling using an out-of-bound external 
wake up mechanism can work to successfully increase the lifetime of a typical 
body-centric wearable network (S-BCN).

1.  Introduction

The wearable wireless sensor devices are nowadays becoming popular. 
A network of these devices can monitor the human body functions and 
its surroundings to provide efficient health and personal care.

In a typical network, the receiver device must be switched on (awake) 
before the sender can transfer the packets. Due to this reason, a
