Mobile IP for Ad Hoc Networks:

Mobile ad hoc networks are temporary networks, with varying network topologies. They communicate beyond transmitter range and are supported by multi hop communication through IP routing. Since Mobile Ad Hoc Network is a roaming network, where the host may be connected through various means to the Internet other than it’s fixed-address domain space, it becomes important for the host to have dynamic network identification. This paper talks about the Mobile Ad hoc networks and how Mobile IP is assigned to the various nodes in the network and their routing strategies. It compares and contrasts the various means used by mobile nodes to get network identification and the best means in terms of avoiding disconnection and quality of service. Introduction: A Mobile ad hoc network 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 arbitrarily. There may be multiple hosts per router. A Mobile ad hoc network is an autonomous system of mobile nodes. The system may operate in isolation, or may have gateways to and interface with a fixed network. In the latter operational mode, it is typically envisioned to operate as a "stub" network connecting to a fixed inter network. Stub networks carry traffic originating at and/or destined for internal nodes, but do not permit exogenous traffic to "transit" through the stub network. Mobile ad hoc network nodes are equipped with wireless transmitters and receivers using antennas, which may be omni-directional (broadcast), highly directional (point-to-point), possibly steer able, or some combination thereof. At a given point in time, depending on the nodes' positions and their transmitter and receiver coverage patterns, transmission power levels and co-channel interference levels, a wireless connectivity in the form of a random, multi hop graph or "ad hoc" network exists between the nodes. This ad hoc topology may change with time as the nodes move or adjust their transmission and reception parameters.
