Decentralized polling with respectable participants

Decentralized Polling with Respectable Participants

We consider the polling problem in a social network where participants care about their reputation: they do not want their vote to be disclosed nor their misbehaving, if any, to be publicly exposed. Assuming this reputation concern, we show that a simple secret sharing scheme, combined with verification procedures, can efficiently enable polling without the need for any central authority or hea...

Efficient Polling Protocol for Decentralized Social Networks

We address the polling problem in social networks where individuals collaborate to choose the most favorite choice amongst some options, without divulging their vote and publicly exposing their potentially malicious actions. Given this social interaction model, Guerraoui et al. [1], [2] recently proposed polling protocols that do not rely on any central authority or cryptography system, using a...

A Polling Model with Reneging at Polling Instants

In this paper we consider a single-server, cyclic polling system with switch-over times and Poisson arrivals. The service disciplines that are discussed, are exhaustive and gated service. The novel contribution of the present paper is that we consider the reneging of customers at polling instants. In more detail, whenever the server starts or ends a visit to a queue, some of the customers waiti...

Polling with batch service

This paper considers a batch service polling system. We first study the case in which the server visits the queues cyclically, considering three different service regimes: gated, exhaustive, and globally gated. We subsequently analyze the case (the so called ‘Israeli Queue’) in which the server first visits the queue with the ‘oldest’ customer. In both cases, queue lengths and waiting times are...
