The goal of Delay Tolerant Networking (DTN) is to take a collection of heterogeneous,
disparate connections between satellites, space assets, ground stations, and ground …

In this paper, we develop a general framework to analyze polling systems with either the
autonomous-server or the time-limited service discipline. According to the autonomous …

We consider the asymptotic variance of the departure counting process D (t) of the GI/G/1
queue; D (t) denotes the number of departures up to time t. We focus on the case where the …

We study the scheduling polices for asymptotically optimal delay in queueing systems with
switching overhead. Such systems consist of a single server that serves multiple queues …

Delay-and Disruption-Tolerant Networks (DTNs) refer to a range of networks with link
intermittency that is mainly driven by mobility, predictable or unpredictable network …

Conventional logic gates are not reversible. A reversible logic gate has the same number of
inputs and outputs with one-to-one correspondence between the input and the output …

A functional law of the iterated logarithm (LIL) and its corresponding LIL are established for a
two-stage tandem queue. The functional LIL and the LIL limits quantify the magnitude of …

In this article we propose methods to estimate the parameters of arrival processes to G/D/1
queueing systems only based on observed departures from the system. The derived …

Understanding the delay performance in mobile ad hoc networks (MANETs) is of
fundamental importance for supporting Quality of Service (QoS) guaranteed applications in …

Queuing delay have significant impact on the performance of network applications. To meet
distinct delay requirements of multi-class end-user traffic (eg, voice, streaming video …
