Research ArticleOpen accessIn the keywordsAn Improved Resource Reservation ProtocolDesire Oulai, Steven Chamberland, Samuel PierreThe classical resource reservation protocol (RSVP) is a flow-based signaling protocol used for reserving resources in the network for a given session. RSVP maintains state information for each reservation at every router along the path. Even though this protocol is very popular, he has some weaknesses. Indeed, RSVP does not include a bidirectional reservation process and it requires refresh messages … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,488 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPerformance Study of Threshold Variations in Temporal Decision Systems for Routing in Vehicular Ad hoc NetworksB. S. Shylaja, V. Mary Anita Rajam, V. Uma Maheswari, Arul SiromoneyProblem statement: Route maintenance and re-discovery are expensive in signaling and computation for routing in Vehicular Ad hoc Networks (VANETs). Hence it was desirable to choose the optimal route during the route selection phase. Approach: In this study, the threshold-based routing protocol β-wt uses the notion of threshold from variable precision rough sets. This protocol was used to evaluate routing … …Journal of Computer Science, Vol. 6, Issue 12 · 9 Nov 2010 · 6,890 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Light-Weight Service Discovery Protocol for Ad Hoc NetworksRanwa Al Mallah, Alejandro QuinteroProblem statement: In mobile ad hoc networks devices do not rely on a fixed infrastructure and thus have to be self-organizing. This gives rise to various challenges to network applications. Existing service discovery protocols fall short of accommodating the complexities of the ad-hoc environment. However, the performance of distributed service discovery architectures that rely on a virtual backbone for locating … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,336 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSclerostin: A Novel Key to Bone and Dental TreatmentGalli Carlo, Lumetti Simone, Manfredi Edoardo et al.Problem statement: Tooth loss can induce dramatical remodeling of alveolar bone because of mechanical loading impairment and strategies to help maintain adequate bone levels for subsequent therapies are sorely needed. Recent discoveries have shown that osteocytes, matrix-embedded cells in bone, respond to mechanical stimulation by modulating the expression of the Sost gene, which encodes for the protein sclerostin. This protein … …Current Research in Dentistry, Vol. 3, Issue 1 · 1 Jan 2013 · 8,157 accessesView PDF Cite
