Additionally, the access point may connect to a costly resource (e.g., a satellite link), or an external network that is susceptible to intrusion. For such reasons and others that concern data availability and response time, MANET applications should check for the existence of the desired data inside the network before attempting to connect to the external data source. An example would be a node that is searching for data that have been requested before by other nodes and are now cached and available to the rest of the nodes. Another example is where there is a group of nodes that have data which may be of interest to other nodes and are willing to share them. These scenarios and others suggest that efficient data search techniques be developed for allowing mobile nodes to find the desired data. Thus the client will search the list of data from server side to have a communication.
