Abstract :
The IEEE 802.11 standard is a widely used protocol for wireless communications. It is a moderately complex algorithm involving collision detection, dynamic backoffs, channel reservations, and acknowledgments. Detailed simulation of 802.11 requires some care, and considerable execution time. We are interested in developing a rapidly executable model of 802.11\´s effect on network behavior. Our interest in this derives from investigations into routing algorithms for large scale ad-hoc networks, executing on parallel architectures. As our interest is in routing and not the MAC layer, a rapidly executed model of 802.11 will accelerate simulations focused on routing issues while giving us "good enough" estimates of packet latency, throughput, and loss
