Power-Aware Epidemics

Power-Aware Hierarchical Epidemics in Peer-to-Peer Systems

Epidemic or gossip-based mechanisms are preferred in several distributed protocols for their ease of deployment, simplicity, robustness against failures, load-balancing and limited resource usage. In flat neighborhood epidemics, peers have similar responsibilities and all participate in gossiping via neighboring peers. We have proposed an energy cost model for a generic peer using flat neighbor...

Flat and hierarchical epidemics in P2P systems: Energy cost models and analysis

In large scale distributed systems, epidemic or gossip-based communication mechanisms are preferred for their ease of deployment, simplicity, robustness against failures, load-balancing and limited resource usage. Although they have extensive applicability, there is no prior work on developing energy cost models for epidemic distributedmechanisms. In this study, we address power awareness featu...

SNR Maximization at CSI Aware AF Relay

This paper concerns two-hop communication over relay-assisted Block fading channel. It is assumed there is not a direct link between the transmitter and the affiliated destination and the communication occurs in two hops through the use of a relay, where the amplify and forward (AF) strategy is employed at this node. In this case, in a Rayleigh block fading channel, the optimal weight function ...

Influence of awareness that results from direct experience on the spread of epidemics

Here we study ODE epidemic models with spread of awareness, assuming that a certain proportion of the hosts will become aware of the ongoing outbreak upon recovery. This study builds on W. Just and J. Saldaña’s work in [1], and is conducted under the same framework, while addressing the influence of the awareness gained from direct experience of the disease. In [1], the authors investigated the...
