Abstract
Peer -to- peer (P2P) file sharing systems as well as mobile ad hoc networks ( MANETs) posses the same decentralized nature. However P2P and MANETs operate on different network layers. A combination of both appears to be promising though it faces several problems using mobile agents in the search phase of peer-to-peer file sharing seems to be a good candidate in reducing this overhead. In this thesis, we study using mobile agents for locating document synchronously. We are interested in locating more documents even if this takes longer time. At the same time. We do not want to flood the network with requests, or misuse the resources at its nodes. The performance of this network and comparing it using both synchronous and asynchronous approaches in locating document. The asynchronous approach shows more success in locating far- from- reach documents, while maintaining a very reasonable level of network traffic and resource consumption.
