Backoff algorithms are one class of collision resolution algorithms used in the medium access control protocols in mobile ad hoc networks. When there are different nodes competing to access a shared channel at the same time, the possibility of collision is highly probable, especially in high traffic load networks. In this paper, the authors explain the possibility of using different values for increments and decrements in the contention windows in order to improve the performance. Mobile Ad hoc NETworks (MANETs) work without requiring any preexisting communication infrastructure.
