Mobile ad hoc network (MANET), an infrastructure-less network which is one of the most popular emerging wireless network. AODV and DYMO are on-demand routing protocols that was designed to meet various needs of Mobile ad hoc network such as security, mobility, flexibility etc. IETF listed on-demand routing protocols in a varying speed of nodes, mobility, and performance metrics. In this paper, we discussed behavior of the two main on-demand routing protocols in network simulation environment, while sending packets from source to destination under free space and two ray propagation models by varying packet rate. We analyzed the performance metrics of mobile ad hoc network in the following heading; average jitter, average end-to-end delay, packet delivery ratio, and throughput are compared with percentage of nodes packet drops.
A mobile ad hoc network (MANET) is a type of ad hoc network that has many free autonomous nodes with no unifying administering node and fixed infrastructure. Manet are mobile, they use wireless connections to connect to various networks be it Wi-Fi connection, or other medium such as cellular or satellite transmission 1.Manet are deficient in fixed topology as it’s regarded as an infrastructure less networks in which as single node has the tendency to function both as a router or host or both. Manet has it’s confrontations as a node requires other neighbor node to forward packets which is a result of nodes limited transmission. These has brought incredible study from researchers who are trying to understand the Routing challenges in Manet. Furthermore, routing algorithm helps in selecting the path each route can follow.
