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...

Hasbullah Awang Had Salleh Graduate School of Arts & Sciences Awang Had salleh Graduate School of Art & Sciences T Technology (General) 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. Through a simulation, a series of experimental studies were conducted to validate and evaluate the performance of DDCBS. The results were compared with existing schemes such as Traffic Class Prioritization based Carrier Sense Multiple Access/Collision Avoidance, Class of Service Traffic Priority-based Medium Access Control, Auto Management of Energy, and IEEE 802.15.4 Standard. The findings reveal that DDCBS performs better than TCP-CSMA/CA, CSTP-MAC, AME and IEEE 802.15.4. The throughput and packet delivery ratio increased by 9% and 23%, respectively. Energy consumption has decreased by 2%, and DDCBS has shown a significant performance by reducing 23% of the packet loss ratio. Thus, the findings demonstrate that DDCBS has improved the network’s stability and fair access among all nodes. Due to the improvement in quality of service (QoS) that DDCBS has demonstrated, it can be used in a highly dynamic environment to improve WBAN performance.
