Abstract

In the design of wireless networks, the medium access protocols have a very large impact on the performance of the network. The IEEE 802.11 is widely accepted technology for the Wireless LANs and is used by wireless networks. This paper presents an analysis of the performance of Distributed Coordination Function DCF for IEEE 802.11 under modified Binary Exponential Backoff BEB Algorithm using Frequency Hoping Spread Spectrum FHSS. In the modified algorithm, the size of Contention Window CW has been changed with the factor of for the first four collisions and the size becomes double thereafter in each subsequent collision. This paper also covers the effects of various parameters in modified BEB Algorithm.
