Supporting healthy and efficient operations in mobile wireless networks is the idea of the mobile ad-hoc networking. This is done by integrating the routing functionality into mobile nodes. The demand for wireless networks will be increased in future as their popularity and deployment are increasing more and more. Improving the speed of wireless networks is the main goal of this research. As a result, the demands of bandwidth which will be continuously raised can be met. Providing a framework to perform the required experiments in an environment which is platform independent is the primary goal. In order to meet this, the basic simulation of routers with Quality of Service should be designed and implemented in Java.
Drawing nodes in a particular network is the main objective of this project. The nodes can be added, deleted, the weight of the node can be changed, and the node can also be removed by making the node weight zero. The best path can also be identified for the designed network.
The design in the existing simulation packages is based on constructing a network model of routers and then the traffic is generated for every node. A number of routers should be simulated when there is an increase in number of nodes and also there will be an increase in the complexity of the simulation as the square of that number.
Thus, a system which provides a new approach for simulating the ad-hoc networks routers is required.
The interest in wireless network infrastructures which support real-time communications has been increased with the emergence of roaming applications. A bandwidth routing protocol is proposed in this project for the support of Quality-of-Service (QOS) in a mobile network. In mobile networks, the QOS routing feature is significant for interconnecting wired networks (for instance, internet, ATM etc). Also, in an individual multichip mobile network, QOS routing protocol can work for real-time applications. Bandwidth allocation and end-to-end bandwidth calculation are included in the QOS routing protocol. By using such a routing protocol, the bandwidth is informed to the source and QOS will be available to the mobile network destination. The establishment of QOS connections in the mobile network and the real time application’s efficient support is allowed by this knowledge.
More efficient call admission control is also facilitated by it. In router interconnection cases, the bandwidth information is used for carrying out intelligent handoff in router gateways and for extending the service of router virtual circuit to mobile networks with probable cooperation of QOS parameters at the gateway. The system performance can be observed in several mobility environments and QOS traffic flows through simulation.
Different performance advantages of protocol which computes the bandwidth information are recommended by the results of simulation. In call admission protocol, it is mainly useful. The performance in the mobile environment is improved by “standby” routing. This improvement is shown by simulation experiments.
