    (IDOSI Publications, 2013) Farooq Umer; Muhammad Adnan; Mustafa Shakir; Izhar-ul-Haq; Mahmood Ashraf Khan; Nasir Iqbal
    Manet has become the most popular network nowadays for communication. Communication is being done without any need of establishing heavy centralized fixed node architecture. Nodes are mobile, so nodes need cooperation of other nodes to maintain route in the network. The topology keeps on changing in MANETS effecting different aspects of network. There are many aspects on which routing depend in a MANET. Many evaluations of comparisonshave been done using different scenarios resulting in different results. A variation of result may be found in different scenarios. We have briefly evaluated a comparison of AODV, OLSR, DSR and GRP protocols. A different scenario was created to evaluate their performances. This paper focuses on the performance of these protocols by four matrices namely throughput, delay, load and retransmission attempts. The overall goal was to determine the more suitable protocol for routing in ad-hoc MANET in a mobile network. Different protocols performed better in different metrics. We have carried out simulations in OPNET tool.
