In the technological era computing network is changing its path from wired to wireless technology and the Mobile Ad-hoc Network (MANET) technology is a great part of it. From last four decades since the wireless technology invented, it has been a major immerging technology in mobile computing. With remarkable qualities of dynamic network topology, it also shows moving nodes. Mobile Ad-hoc Network (MANET) is collection of multi-bounce wireless portable nodes. It works with each other without incorporated control or set up framework. Routing in MANET is a basic task because of dynamic environment. The wireless connection in MANET is very sensitive because of moving element nature. Due to wireless technology, Mobile Ad-hoc Network (MANET) is used in Military operations, Sensor Networks, Rescue operations. To manage the moveable network nodes, there is a need of set of protocols. Flat Routing Protocol is one the most used protocol in MANET.
