The Comparison Of Wireless AD HOC Net Route Protocols

The Ad Hoc Networks is a wireless mobile communication network with a set of mobile nodes with wireless sending and receiving device, which is set up temporarily without depending on the preset basic facilities. The mobile node of the network utilizes its own wireless sending and receiving device to exchange information. When each other of the nodes are not within the range of communication, they can realize communication with the aid of the relay of some middle nodes. The Ad Hoc Networks can be widely used in military affairs, sensor networks, rescue and relief work and accidents etc. which can not be served by the network or need communication temporarily.Here, the development of the Ad Hoc Networks and current situation is introduced and its characteristics and system structures are analyzed first. Then, many kinds of network route protocols which can be used in Ad Hoc Networks are compared and analyzed. Finally, it is determined that the simulating route protocols of this theory are AODV, DSR, TORA route protocols.On the basis of swarm Intelligence, two kinds of even distribution theory models are put forward, which are based on the divergent and convergent viability. A simple introduction has also been carried on to the characteristics of the OPNET software. On the case of the tests of uniform speed and variable speed and the changeable number on the nodes, it can be drawn the conclusion that what kind of the route can be realized optimumly by which kind of model, rate and how many nodes using OPNET software and offers the consulted arithmetic, models and datum for the later design and application of the real system.
