Real-time Bandwidth and Energy Efficient IEEE 802.15.4 for Medical Applications
Pardeep Kumar, Mesut Güneş, Jochen Schiller, Abd Al Basset Almamou – 2008
The recently standardized IEEE 802.15.4 protocol provides many appealing features, such as low power, low cost, low data-rate, simplicity, and timeliness guarantee for delay-bound, energy, and bandwidth critical applications. However, when treating applications with such requirements as in the medical field, several problems arise, triggering the need of an efficient enhancement of the IEEE 802.15.4 protocol including the fine tuning of its parameters. In this paper, we discuss the suitability of the protocol and explore its limitations for health care applications. We propose a solution to overcome those limitations and derive the most efficient IEEE 802.15.4-based network parameters setting for urgent medical services.
