A Mobile Ad-hoc Network (MANET) is a collection of mobile devices dynamically forming a communication network without any centralized control and pre-existing network infrastructure. Consequently, routing becomes a vital factor and a major challenge in such type of network. This research aims to study the impact of four IETF (Internet Engineering Task Force) standardized routing protocols on MANETs and thereby comprehensively analyzes their performance under varying network sizes and node mobility rates. The four routing protocols that are considered in the analysis are Optimized Link State Routing (OLSR), Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Temporary Ordered Routing Algorithm (TORA).The main objective of congestion control is to limit the delay and buffer overflow caused by network congestion and provide better performance of the network. To maintain and allocate network resources effectively and fairly among a collection of users is a major issue. The resources shared mostly are the bandwidth of the links and the queues on the routers or switches.
