As in real world the movement of nodes are almost always random. And the most important characteristics is the dynamic topology which is a consequence of node mobility, nodes can change position quite frequently, which means we need a routing protocol that quickly adapts to topology changes. Now, days there are more than billion wireless devices in use. And every devices are topology independent. Therefore, the wireless mobile computers or Mobile Ad Hoc Networks (MANET) have become very necessary.
