We present a general framework for carrying out perturbation analysis in Stochastic Hybrid
Systems (SHS) of arbitrary structure. In particular, Infinitesimal Perturbation Analysis (IPA) is …

This paper presents an algorithm for maximizing the lifetime of a sensor network while
guaranteeing an upper bound on the end-to-end delay. We prove that the proposed …

Dynamic voltage scaling is used in energy-limited systems as a means of conserving energy
and prolonging their life. We consider a setting in which the tasks performed by such a …

The problem of online packet scheduling to minimize the required conventional grid energy
for transmitting a fixed number of packets given a common deadline is considered. The total …

It has been shown that by using appropriate channel coding schemes in wireless
environments, transmission energy can be significantly reduced by controlling the packet …

We consider discrete event systems involving tasks with real-time constraints and seek to
control processing times so as to minimize a cost function subject to each task meeting its …

We consider discrete event systems (DESs) involving tasks with dependability requirements
in the form of real-time constraints. We seek to control their processing times so as to satisfy …

We study online energy-efficient packet scheduling in a multi-user AWGN channel. The
objective is to minimize the overall energy consumption in both transmission and circuit by …

This paper studies the problem of energy efficient routing in a sensor network with multiple
gateways. Due to the complexity of this problem, we divide it into two sub-problems: the …

In wireless networks, there is an ever-increasing demand for higher system throughputs,
along with growing expectation for all users to be available to multimedia and Internet …
