Performance evaluation of ECMA-368 medium access control protocol for UWB ad-hoc networks Arianpoo, Nasim
Abstract
Ultra Wideband (UWB) is an emerging technology for high rate, short range wireless communications. Its unique features such as low power operation, robustness to multi-path fading, and accurate positioning capabilities makes UWB a good platform for wireless personal area networks (WPANs). One of the recent UWB standards standardized by the European Computer Manufacturers Association (ECMA) International is the ECMA- 368, which defines the physical (PHY) and media access control (MAC) layers for high rate WPANs. The MAC protocol in ECMA-368 has a superframe structure. Each superframe is divided into three different time periods. The beacon period is used for control purposes. The distributed reserved protocol (DRP) period allows devices to reserve bandwidth for data transmission. The PCA (prioritized contention access) period supports contention-based access between different traffic classes. In this thesis, we propose an analytical model to evaluate the performance of the ECMA-368 MAC protocol. We assume that packets follow the Markovian Arrival Process (MAP) and various service times can be modeled by different phase type distributions (PHYs). We apply the Matrix Geometric Method (MGM) technique and model the system as a MAP/PHY/1 queueing system. We derive the probability mass function (pmf) for the number of the packets in the queue, as well as the cumulative distribution function (CDF) for the waiting time of the packets in the queue. The correctness of our proposed analytical model is validated via simulations. We create the ECMA-368 module by using the OPNET simulator. Analytical and simulation results are presented under different scenarios

Ultra Wideband (UWB) is an emerging technology for high rate, short range wireless communications.
Its unique features such as low power operation, robustness to multi-path
fading, and accurate positioning capabilities makes UWB a good platform for wireless
personal area networks (WPANs). One of the recent UWB standards standardized by
the European Computer Manufacturers Association (ECMA) International is the ECMA-
368, which defines the physical (PHY) and media access control (MAC) layers for high
rate WPANs. The MAC protocol in ECMA-368 has a superframe structure. Each superframe
is divided into three different time periods. The beacon period is used for
control purposes. The distributed reserved protocol (DRP) period allows devices to reserve
bandwidth for data transmission. The PCA (prioritized contention access) period
supports contention-based access between different traffic classes.
In this thesis, we propose an analytical model to evaluate the performance of the
ECMA-368 MAC protocol. We assume that packets follow the Markovian Arrival Process
(MAP) and various service times can be modeled by different phase type distributions
(PHYs). We apply the Matrix Geometric Method (MGM) technique and model the
system as a MAP/PHY/1 queueing system. We derive the probability mass function (pmf) for the number of the packets in the queue, as well as the cumulative distribution
function (CDF) for the waiting time of the packets in the queue. The correctness of our
proposed analytical model is validated via simulations. We create the ECMA-368 module
by using the OPNET simulator. Analytical and simulation results are presented under
different scenarios
