چکیده

Peer-to-peer is a popular distributed overlay network due to its easy deployable property. Mobile computing and communications are improving day by day. With this advancement in technologies, mobile p2p has revealed its attractions. But resource constraints such as limited bandwidth, power and memory along with nodes mobility make it challenging to build a scalable and a robust mobile p2p network. Content discovery and locating are crucial that affects the performance of the system. Data caching and adopting dynamic topology of the mobile p2p systems are important to accelerate the effectiveness the system. In this project we discuss these issues to enhance the applicability of mobile p2p systems and give some guidelines to the researchers in this field.

A Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory

The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...

Improving Performance of Peer-to-peer Systems by Caching Contents

ZHANG, QINGHUA Improving performance of peer-to-peer systems by caching. (Under the direction of Dr. Douglas Reeves). Recently, Peer-to-Peer (P2P) has attracted a great deal of interest in industry and research literature. P2P systems are application layer networks, in which logically distinct computing elements peers, bear comparable roles and responsibilities. P2P enables peers to share resou...

k-NN Multimedia Retrieval in Unstructured Peer-to-Peer Networks

AbstractRecent years saw the rapid development of peer-to-peer (P2P) networks in a great variety of applications. However, similarity-based k-nearest-neighbor retrieval (k-NN) is still a challenging task in P2P networks due to the multiple constraints such as the dynamic topology and the unpredictable data updates. Caching is an attractive solution that reduces network traffic and hence could r...
