This paper proposes a new routing algorithm called Power Aware On-Demand Multicast Routing protocol which maximizes the lifetime of an adhoc network. The algorithm is based on the routing discovery phase and establish a resilient path. At routing discovery phase, the forwarding members are identified with suitable energy capacity. The optimal route confirms the resilience with respect to energy...

Trust is essential in human interaction and this naturally reflects within computer science context, in particular inside internet-based communities. In this work we present an approach based on social networks, which revealed several useful properties, as the small world effect, that can be usefully exploited in addressing the question of trust. We aim at reproducing the behaviour individuals ...

In this paper we describe R-P2P, a novel system meant to support the search and retrieval of data in a certain location. R-P2P couples opportunistic wireless communications between mobile devices with an interconnected network of throwboxes. The set of throwboxes implements a distributed and localized data storage. Overall, the system integrates in an on-demand, delaytolerant fashion two main n...

We present the set of protocols and procedures that constitute Inter-Domain Policy Routing (IDPR). IDPR includes the virtual gateway protocol, the flooding protocol, the route server query protocol, the route generation procedure, the path control protocol, and the data message forwarding procedure. Contributors The following people have contributed to the protocols and procedures described in ...

several semantic image search schemes have been recently proposed to retrieve images from the web. however, the query context is regularly ignored in these techniques and hence, many of the returned images are not adequately relevant. in this paper, we make use of context to further confine the outcome of the semantic search engines. for this purpose, we propose a hybrid search engine which uti...

Vehicular sensor networks are an emerging network paradigm, suitable for various applications in vehicular environment making use of vehicles’ sensors as data sources and Inter-Vehicle Communication systems for the transmissions. We present a solution, based on vehicular sensor networks, for gathering data from a certain geographic area while satisfying with a specific delay bound. The method l...
