摘要：Ad hoc networks are self forming, auto configuring without any kind of pre-existing infrastructure. With the dearth of pre-defined topology there is no router or controlling device. Two mobile nodes can exchange data directly if they are in the defined range of each other. If not, nodes can communicate via a multi-hop route with the help of other mobile nodes. In this paper we have proposed an approach to reduce the data traffic and to increase data available in the mobile ad-hoc network. In the proposed method, MANET is server client based network, means a mobile host acts as a server and fulfill the others node’s request. Each mobile node has a buffer for temporary storing data segment for a particular time, If a mobile node requests for a particular data segment and the request is multi hoped, then first request is sent to its (requester) neighbor node, neighbor node first match requested data segment with holed copy of data segment, if it is matched the request will be responded by this neighbor otherwise request will be routed to mobile server. In this way the overhead of the server and data traffic in the server zone will be reduced. The proposed method reduces time consumed by multiple nodes and data availability will be enhanced.
