'''Mobile Adhoc Network: Routing Protocols MANET'''

An ad hoc network is a collection of mobile nodes using wireless network interfaces to communicate among themselves without using the existing network infrastructure or centralized administration. In the areas where there is little or no infrastructure is available or the existing wireless infrastructure is expensive and inconvenient to use, Mobile Ad hoc Networks, called MANETs, are becoming useful. A mobile ad hoc network is a set of mobile nodes able to communicate with other nodes in their surroundings. These wireless communications happen in a peer-to-peer manner instead of static(fixed) network infrastructure, dynamically forming a temporary network to exchange information without using any pre-existing fixed network infrastructure. They are going to become integral part of next generation mobile services. A MANET consists of mobile platforms (e.g., a router with multiple hosts and wireless communications devices) herein simply referred to as "nodes", which are free to move about randomly. The nodes may be located in or on airplanes, ships, trucks, cars, perhaps even on very small devices, and there may be multiple hosts per router. The network topology in a MANET usually changes with time thus nodes are free to move arbitrarily.
