Content Distribution Networks have been attracted a great deal of attraction in recent years. Replica placement problems (RPPs) as one of the key technologies in the Content Distribution Networks have been widely studied. In this paper, we propose an optimization model with server storage capacity constraints for the RPPs. Furthermore, part of the objective function is represented as a Multiple...

Content dissemination networks are pervasive in todays’ Internet. Examples of content dissemination networks include peer-to-peer networks (P2P), content distribution networks (CDN) and information centric networks (ICN). In this paper, we propose a new system design for information centric networks which leverages opportunistic searching, routing and caching. Our system design is based on an h...

Peer-to-peer networks have often been touted as the ultimate solution to scalability. Although cooperative techniques have been initially used almost exclusively for content lookup and sharing, one of the most promising application of the peer-to-peer paradigm is to capitalize the bandwidth of client peers to quickly distribute large content and withstand flash-crowds (i.e., a sudden increase i...

Mobile ad-hoc networks (MANETs) and peer-to-peer (P2P) systems are ubiquitously emerging technologies which share a common underlying decentralized networking paradigm. Deploying Peer to Peer architecture over Mobile ad hoc networks results in an efficient content distribution network. However most of the time MANETs are intermittently connected (No complete path exists from source to destinati...

this paper presents a multi-objective formulation for optimal siting and sizing of distributed generation (dg) resources in distribution systems in order to minimize the cost of power losses and energy not supplied. the implemented technique is based on a genetic algorithm (ga) and weight method that employed to obtain the best compromise between these costs. simulation results on 33-bus distri...

key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. to establish a secure communication, two nodes must share common key from their key-rings. otherwise, they can find a key- path in which ens...

Fact-checking is a thriving journalistic discipline that, in recent years, has gained great prominence as tool combating disinformation. The effectiveness of the work carried out by these initiatives depends not only on quality their content, but also ability to reach large audiences through same channels which disinformation spreads. In this context, we consider it important know what extent f...
