Performance Analysis of Preamble-Based TDMA Protocol for Wireless Body Area Network

Abstract

A wireless body area network (WBAN) allows the integration of low power, invasive or non-invasive miniaturized sensors around a human body. Each intelligent sensor has enough capability to analyze and process the physiological parameters and to forward all the information to a central intelligent node for disease management, diagnosis and prescription. The data transmission rate of various biosensors is heterogeneous. Furthermore, the limited energy resources and computational power of these sensors have urged the development of low power energy efficient medium access control (MAC) protocol. This paper studies the performance of Preamble-Based time division multiple access (PB-TDMA) protocol for a heterogeneous non-invasive WBAN. Simulation results show that the performance of PB-TDMA protocol outperforms S-MAC and IEEE 802.11 DCF in terms of throughput and power consumption.

Energy-efficient MAC protocols for wireless body area networks: Survey

“…TDMA based contention-free MAC protocols such as PACT [9], LEACH [10], FLAMA [11] and HEED [12] are unable to satisfy the stringent requirements of WBAN. Other MAC protocols such as Preamble-based TDMA [13], Heartbeat Driven MAC (H-MAC) [14], Reservation-based Dynamic TDMA (DTDMA) [15], Distributed Queuing Body Area Network (DQBAN) [16], [17] and [18] have also been investigated for WBAN in recent literature. A comparison between TDMA and CSMA protocols are summarized in TABLE I, as reported in literatures.…”

A Review of Wireless Body Area Networks for Medical Applications

“…An alternative solution is to use TDMA-based protocols for a WBAN. Therefore, we analyze the performance of a preamble-based TDMA [38] protocol for an on-body sensor network. We use ns-2 [39] for extensive simulations.…”
