Abstract

In this paper, we present a model that incorporates nodes with role of proxy in a MANET environment. MANET is specifically characterized by high mobility of network nodes and frequent changes of direct visibility. In partially connected ad hoc networks, the destination is not always reachable. In our model we need a proxy node to relay messages to the destination. Proxies are nodes that have high probability of reaching the destination. In our scheme, when a source sends a request for a destination and the destination is not reachable, then some of the nodes in the network will choose to become the proxy for the destination. The model has been evaluated via simulation in order to confirm the feasibility of his application in real conditions. In our measurements we use one proxy node in order to broadcast the messages in the destination.
