  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: Required MAC protocol features for non-medical BAN Date Submitted: 13-05-2008 Source: Ranjeet Kumar Patro, Kiran Bynam, Giriraj Goyal, Arun Naniyat Contact: Ranjeet Kumar Patro Voice: +91- 80 - 4181 9999, E-Mail: rkp.atd@samsung.com, ranjeet.patro@gmail.com Re: Abstract: Some of the required MAC attributes are captured analyzing the non-medical traffic Purpose: To consider obtained MAC attributes for body area network MAC development Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and maybe made publicly available by P802.15. Slide 1

Classification Multiple Access Protocol Contention Conflict Free Hybrid Reservation-ALOHA PRMA Static Resolution Dynamic Resolution Static Allocation Dynamic Allocation • TDMA • FDMA • CDMA • Polling • Token Ring ID Probabilistic Time of Arrival Probabilistic • ALOHA • S-ALOHA • 802.3 MAC • 802.11 DCF Slide 2

  3. Non-medical BAN Traffic Slide 3

  4. MAC protocol should: Distinguish and prioritize the traffic based on its real-time requirements - Need of coordinator - Coordinator should have control over the order of transmission Have low-latency characteristics to support real-time behavior - Fixed bandwidth may required for CBR traffic Have contention based access for VBR traffic - Contention between real-time VBR and non-real-time VBR may degrade the performance of real-time VBR - First packet of real-time VBR may contend, have mechanism to reserve channel for other VBR packet in a flow Distinguish and treat differently packets in a real-time VBR flow Maximize utilization of the medium - No idle channel Energy consumption is critical for BAN nodes used for motion/posture detection Slide 4
