Survey and overview of Mobile Ad-Hoc Network routing protocols

In Early 1990 researchers have shown a keen interest in Mobile Ad-hoc Network. The absence of infrastructure and its dynamic, diverse principal characteristics has made it more popular as well as vibrant because of it the Internet Engineering Task Force (IETF) is established. Not only bigger company and organization, different institutes are also working on MANET. It applies the TCP/IP protocol stack with slight modification for end to end communication. In MANET Routing is the toughest task because nodes works as router and host at the same time with the changing environment, infact for this many researchers have proposed new protocols and have shown that the protocol proposed works well and is improved over different scenario, strategy and conditions. In contrast to above it is quite challenging that which protocol performs best under different scenario, strategy and condition. Therefore, in this paper we provide a survey and overview of different routing protocols even survey of complexity comparison is also performed to find out which protocol will fit for larger network or so.
