Routing Protocols in Ad-hoc Network?

The latest advancement in wireless technology and its applications received a lot of attention. An ad hoc network is one such recent technology, which gives a new paradigm for wireless self-organised networks. Ad hoc networks are simple peer-to peer networks, selforganized and with no fixed infrastructure. Ad-hoc network is a concept in computer communication which means that user wanting to communicate with each other forms a temporary network, without use of centralized administration. Each node in the network acts both as host and router and must therefore willing to forward packet for other node. For this purpose routing protocol is needed. A Mobile Ad-hoc Network (MANET) is a temporary wireless network composed of mobile nodes without any permanent infrastructure. Each node not only operates as an end system, it also acts as a router to forward packets on behalf of other nodes [1]. One of the best features of MANET is its flexibility and can configure itself in the fly and thus very suitable for the emergency situation
