It is a well-known issue that the polling I/O, such as select() and poll(), has a poor scalability. As a solution of the problem, we previously proposed the interval control technique of the polling I/O, which eases excessively frequent invocations of the polling I/O [1]. Although the benchmark tests proved that the technique effectively reduced the service latency, it still has a problem of hi...

We consider a networking subsystem for message–passing clusters that uses two unidirectional queues for data transfers between the network interface card (NIC) and the lower protocol layers, with polling as the primary mechanism for reading data off these queues. We suggest that for accurate mathematical analysis of such an organization, the values of the system’s states probabilities have to b...

While drivers are not expected to vote while driving, VANETs can be an excellent media for dissemination of decentralized regional polls and for prerecorded votes/opinions on regional issues in a decentralized opinion poll. We propose and evaluate heuristics for scheduling messages in a VANET broadcastingbased dissemination of decentralized opinion polling data among self-interested participant...

This paper is concerned with both the mean delay and the probability of cell loss that bursty arrivals incur in an ATM switching system which can be modeled as a finite capacity polling system with nonexhaustive cyclic service. The arrival process to each input port of the system is assumed to be bursty and is modeled by an Interrupted Bernoulli Process(IBP). A practical polling system with fin...

We consider a high speed ATM bus, which can serve a small number of stations (~ 16). The bus is slotted and each slot is long enough to contain one ATM cell. Transmission on the bus is controlled by an arbitrator. Each station sends its status information to the arbitrator at regular intervals. Based on this information the arbitrator makes polling decisions. Due to transmission and processing ...

This paper is concerned with the mean delay and the probability of cell loss that bursty arrivals incur in an ATM switching system which can be modeled as a finite capacity polling system with nonexhaustive cyclic service. The arrival process to each input port of the system is modeled by a Markov Modulated Bernoulli Process(MMBP) which is able to describe the bursty and correlated nature of th...

In this paper we develop a well-established financial model to investigate whether bubbles were present in opinion polls and betting markets prior to the UK’s vote on EU membership on 23 June 2016. The importance of our contribution is threefold. Firstly, our continuous-time model allows for irregularly spaced time series—a common feature of polling data. Secondly, we build on qualitative compa...

In a single server polling system, the server visits the queues according to a routing policy and while at a queue serves some or all of the customers there according to a service policy. A polling (or scheduling) policy is a sequence of decisions on whether to serve a customer, idle the server, or switch the server to another queue. The goal of this paper is to nd polling policies that stochas...

We consider an exhaustive polling system with three nodes in its transient regime under a switching rule of generalized greedy type. We show that, for the system with Poisson arrivals and service times with finite second moment, the sequence of nodes visited by the server is eventually periodic almost surely. To do this, we construct a dy-namical system, the triangle process, which we show has ...

Bluetooth is a universal radio interface in the 2.45Ghz frequency band, which will enable users to connect a range of small electronic devices. Any two or more Bluetooth-enabled devices that come within range of each other can set up an ad hoc connection, called a piconet. Within a piconet, the unit that establishes the piconet becomes the master and the rest of the units act as slaves. The mas...
