A Mobile Ad hoc Network (MANET) is a self-directed system consisting of mobile nodes including routers and hosts connected by wireless links without base stations, representing a transitory network, the Backoff algorithm corresponding as an element of Media Access Control (MAC) protocol which used to pass up collision in the Mobile Ad hoc Networks (MANET’s). Many Backoff algorithms have been proposed to improve network performance, mainly when a node gains access the network channel while the other nodes still argue for a time period. One of these algorithms is Fibonacci Backoff which reduces the differences between simultaneous contention window sizes. Another proposed Backoff algorithm is the Pessimistic Linear-exponential Backoff which uses a mixture of two increment series; Exponential Backoff and Linear Backoff. This research presents a new Backoff algorithm called Pessimistic Fibonacci Backoff (PFB) Algorithm to reduce the differences between successive contention window sizes using end-to-end delay, normalization and packet delivery fraction efficiency measures. This new algorithm uses the Pessimistic Backoff algorithm structure using a Fibonacci increment series waiting time.
