Performance analysis of Packet Loss Concealment in mobile environments with a two-state loss model

Abstract

This paper presents and exercises a model to estimate the performance of Packet Loss Concealment (PLC) in wireless field environments. In particular, we estimate the probability of successfully receiving a random packet transmitted over an unreliable wireless link where a packet loss concealment algorithm such as the IETF's RFC 2198 standard schemes 1 and 2 are used. The model assumes a channel with a two-state loss system. Results generated are useful in understanding how packet loss concealment schemes can be designed to support high quality for real-time wireless applications such as VoIP on ad hoc networks.
