Abstract
In this paper, an analytic model is present for evaluating the MAC layer Collision Probability and mean delay at wireless nodes using the Distributed Coordination Function of IEEE 802.11 MAC Model. This model is valid for finite loads and can account for arbitrary arrival patterns, packet size distributions and number of nodes. Each node is modeled as a discrete time M/G/1 queue and impact of packet collisions, the resulting back-offs as well as the packet size distribution. We analyze this Model for different number of nodes in any network. The impact of arrival pattern on collision probability and delay is also analyzed.
