With current advances in technology, wireless networks are increasing in popularity. Mobile Ad-hoc network (MANETs) is a collection of mobile nodes connected with wireless links. MANET has no fixed topology as the nodes are moving constantly form one place to another place. In Ad-hoc networks, nodes can perform several actions like sending packets, forwarding packets, responding to routing messages, sending recommendations among others. The set of performed actions define the node’s behavior. All the nodes must cooperate with each other in order to route the packets. A routing protocol is used to find routes between mobile nodes to preserve data integrity, delivery, throughput, delay, packet loss for trust management in mobile Ad-hoc networks. This paper discusses the influence of the backoff initial contention windows algorithm and better performance based on metrics such as packet delivery ratio, throughput, average end- to-end delay and total energy consumption by using the network simulator (NS-2).
