Abstract / Description

In this paper we extend our recent work [3] by analyzing the behavior of mobility scenario in saturation conditions for evaluating packet delays. For the first time we have shown that the normalized measure of dispersion for service time intervals and offered load dependency holds for multi-hop IEEE 802.11 wireless networks with mobile nodes, as well. Thus this paper not only extends and validates our previous results but also establishes that wireless mobile networks have the similar dependency pattern. We further extend this work by showing that the service time intervals do not follow exponential distribution but instead follow gamma distribution. The patterns for the shape parameters are also established for accurately computing average end-to-end packet delay for mobile networks. The analytical model presented in this paper has been verified through extensive simulations.
