Rescue efforts during natural disasters, military applications on battlefields, and other crucial situations when the current infrastructure is insufficient are good candidates for IEEE 802.11-based wireless ad hoc networks fails. Since the battery life of nodes in these networks is limited, the Reduced packet collision is crucial; otherwise, nodes would suffer energy required for packet transmission must be increased. Performance in these wireless networks is greatly influenced by the packet transmission process. The authors have proposed several packet transmission techniques depicted with Markov chain models to enhance network performance. However, because of the high collision rate, these methods have not proved effective for dense networks. In this paper Comparison of several Back off Algorithms are discussed and Analysed for the need to improve the network performance.
