A Performance Comparison of Different Backoff Algorithms under Different Rebroadcast Probabilities for MANET's
The backoff algorithm is a part of Media Access Control (MAC) protocol which used to avoid collision in the Mobile Ad hoc Network (MANET). When the nodes in the network try to access the channel, one of these nodes gains access the channel while the other nodes still contend for a time period. Many backoff algorithms have been proposed to improve network performance. One of these algorithms is Fibonacci increment backoff (FIB), FIB algorithm achieves higher throughput than the exponential backoff that is used by the standard IEEE 802.11 when it used in a mobile ad hoc network. The Pessimistic Linear-exponential Backoff (PLEB) is another proposed backoff algorithm which uses a combination of two increment behaviors; Exponential backoff and Linear backoff this scheme merges the advantages of the two increment behaviors. Exponential increments give enough backoff time to enhance the network throughput by reducing the number of transmission failures, and the linear increment reduces the average packet delay. Ad hoc On demand Distance Vector (AODV) routing protocol use a demand-driven route establishment procedure. AODV maintain the route table at each node. This paper uses different backoff algorithms at different values of rebroadcast probability.
