Mobile Ad-hoc Network (MANET) is a very powerful field in the progress of Wireless network. Over the past years Wireless ad-hoc network become most stimulating and vital field due to the popularity of mobile devices and wireless network. MANET is a network with many autonomous nodes i.e. mobile devices. MANET uses dynamic topology, wireless links, decentralized network and doesn’t need any cellular infrastructure. The main usage area of MANET is Military scenarios, Sensor Networks, Rescue operations, Student on campus, Conferences etc. MANET is rapidly deployable and selfconfiguring. Due to highly dynamic environment routing in MANET is a very critical task. This paper shows an overview of routing protocols in MANET. This paper aims at the advantages and problems of MANET with the issue of improving the future security.
As the importance of computer increases it also build up the connectivity demand. Wired solutions are used from a very long time, but the demands for wireless solution are increasing for connecting to the Internet, exchanging information, send and receive E-mail messages etc. Mobile Ad-hoc network (MANET) becomes one of the most capable fields for research. MANET is a wireless adhoc network. A MANET can be connected to internet or external network and can be a standalone network. MANET is a Latin word which means “for this,” or “for this purpose only”. Figure 1 shows the structure of MANET. Figure 1: structure of MANET A MANET is a group of self-governing wireless mobile nodes which can interchange data in dynamic manner. Due to the mobile behavior of nodes the network structure is dynamic. The network is self-deploying and decentralized. The nodes in MANET act as both router and as a host and network topology changes rapidly and decision taken in a distributed manner. Due to dynamic behavior of network, routing for MANET is a daring task and wireless page link become highly error prone in MANET. Security, reliability, availability, scalability, quality of service is some of the requirements of MANET.
