Abstract

In this paper, we present the role of proxy service in a MANET environment. MANET is specifically characterized by high mobility of network nodes and frequent changes of direct visibility. High dynamicity affects the design and implementation of distributed applications by significantly increasing their complexity, to consider not only routing and node configuration issues, but also the possible mobility of software components and the loss of direct connectivity during service provisioning. The proxy role is assigned dynamically in a completely decentralized way. Proxies exploit code mobility to install only when and where needed. In this work, we estimate and compare the performance of routing protocols for ad-hoc networks, namely Ad Hoc On-Demand Distance Vector protocol (AODV) and Dynamic Source Routing (DSR). We use the file transfer protocol to measure the performance of our model. The protocol provides file downloading from a dynamically discovered service component available in a MANET locality, even if the server moves during file transfer.
