Dynamic duty cycle and backoff scheduling mechanism for wireless body area network

Wireless Body Area Network (WBAN) is an emerging technology based on wireless sensors on, around, or in a human body to exchange information between sensors to a coordinator connected to remote stations for data analysis. The traditional WBAN uses IEEE 802.15.4 standard, where communication is based...

description Wireless Body Area Network (WBAN) is an emerging technology based on wireless sensors on, around, or in a human body to exchange information between sensors to a coordinator connected to remote stations for data analysis. The traditional WBAN uses IEEE 802.15.4 standard, where communication is based on Medium Access Control (MAC) layer. However, this type of communication has degraded the overall network performance. This study proposed a Dynamic Duty Cycle and Backoff Scheduling mechanism (DDCBS) in IEEE 802.15.4 MAC protocol to control the active period of the superframe structure for coordinating and controlling channel access between nodes that can enhance the network performance. DDCBS consists of a Dynamic Next Beacon Interval and Superframe Duration scheme for adapting the successive values of beacon order and superframe order and a Dynamic Backoff Period scheme for adapting the value of the backoff period.
