Packet Scale Rate Guarantee (PSRG) is a node model used by IETF for Expedited Forwarding, a priority service defined in the context of Differentiated Services [10]. We review probabilistic performance bounds that apply to PSRG nodes, and improve a previous bound for loss probability.

Collecting the real human movement has drawn significant attention from research community since a better understanding of human movement could provide new insights in network protocol design and network management for wireless networks. However, previous projects have only collected either location trace or the ad hoc contact trace. A comprehensive trace of real human movement, in which both t...

— Epidemic algorithms have been recently recognized as robust and scalable means to disseminate information in large-scale settings. Information is disseminated reliably in a distributed system the same way an epidemic would be propagated throughout a group of individuals: each process of the system chooses random peers to whom it relays the information it has received. The underlying peer-to-p...

The two-dimensional probabilistic cellular automaton Epidemic models the spread of an epidemic without recovering on graph. We discuss some well-known and less well-known properties of Epidemic on a finite grid and its analogous on the infinite square lattice: the Eden model. This survey is intended for non-probabilists and gives a detailed study of the robustness of a cellular automaton with r...

background and aims: the world is threatened by disease outbreak that reaches a public health emergency of international concern, studies to inform public and agencies for effective containment strategy are necessary. several studies provided vital information of the dynamics and control of ebola epidemic outbreak in west africa. methodologies and techniques in those researches have to be revie...

DTNs (Delay/Disruption-Tolerant Networks) composed of mobile nodes in low node-density environments have attracted considerable attention in recent years. In this paper, we propose a CD-BCAST (Contact Duration BroadCAST) mechanism that can reduce the number of message forwardings while maintaining short message delivery delays in DTNs composed of mobile nodes. The key idea behind CD-BCAST is to...

In Disruption Tolerant Networks, packet forwarding scheme has a major drawback in terms of network congestion. In order to solve this problem, a New Adaptive Routing Proposal (NARP) has been proposed NARP uses the message forwarding probability scheme in order to increase the delivery ratio and bandwidth utilization. Also, NARP arranges the dropping sequence based on their assigned priority. Th...
