Capability aware AODV algorithm in ns-2 environment

In the present scenario, mobile communication is being widely used in the areas where infrastructure-based telecommunication systems are unavailable or to deploy one is not cost effective. However, often users suffer due to the fact that mobile devices have very low computational capability and thus are incapable of executing many applications with higher resource requirements. In a Mobile Ad-hoc Network (MANET) environment, when a node (a mobile device) is unable to accomplish a job, the job may be transferred to other nodes, which can fulfill its requirements in terms of resources. In ad-hoc network-based environments, such nodes should be found on demand, i.e. an algorithm should reach every node and match the requirements of a job with the capability of each node. This paper particularly emphasizes on the potentials of using PDAs or laptops of users within an office or in a meeting place. Users can submit their job requirements and then the request will pass through the MANET in order to search for a suitable node that would be able to respond back to the user. This paper proposes a Capability Searching Algorithm (CSA) for using in such scenario. CSA gathers information regarding the capability of a node during route discovery and users later can use this information in selecting the node and the best route to that node.
