Mobile Ad-Hoc Network (MANET) is a collectionof two or more devices or nodes or terminals with wireless communications and networking capability that communicate with each other without of any centralized administrator also the wireless that can dynamically form a network to exchange information without using any existing fixed network infrastructure. And it’s an autonomous system in which mobile hosts connected by wireless links are free to be dynamically and sometimes acts as a router at the same time. With some restriction of wired communication wireless technology comes into the picture. The emphasis in this paper is concentrated on Mobile Ad- Hoc Networks. They can be set up anywhere without any need for external infrastructure (like wires or base stations). This can be a standard Wi-Fi connection, or another medium, such as a cellular or satellite transmission [1]. This paper includes working of some Proactive, Reactive and Hybrid protocols that make communication possible it also includes its advantages, limitations and applications of MANET. Protocols discussed in this paper are DSR, AODV, TORA, FSR, ZRP, WPR etc.
