Title
Estimation of Implementation Losses in MAC Protocols for Wireless CDMA Networks
Abstract
This paper presents an analysis of implementation losses in feedback channel state information (FCSI) based MAC protocols for the up-link (UL) of a centralized asynchronous CDMA packet radio system. Such protocol can be used in different segments (or domains) of the future wireless IP networks including WCDMA cellular networks, wireless LANs and Ad Hoc networks. The motivation behind these protocols is to control the channel access by statically or dynamically changing packet transmission permission probability (TPP), also referred to as persistence probability, depending on FCSI. This is supposed to keep the UL load under a certain threshold depending on the QoS requirements. As the main contribution of this paper, effects of the feedback delay, access delay, and imperfect channel sensing are taken into account simultaneously in the analysis. These effects are referred to as imperfections. For performance analysis the system sensitivity functions are introduced. These functions represent the relative performance losses due to the imperfections, which are also referred to as implementation losses. The tradeoff between throughput, outage probability and packet delay in the presence of imperfections is discussed based on numerical results for a number of queuing system models.
