The popularity of wireless sensor networks has grown rapidly in recent years, with new
directions including healthcare monitoring and disaster response. This increased use in …

In this work, we develop an analytical framework to investigate the behavior of the
communication links of a node in a random mobility environment. Analytical expressions …

The vision of researchers to create smart environments through the deployment of
thousands of sensors, each with a short range wireless communications channel and …

Reliability is one of the most important performance measures for emerging technologies.
For these systems, shortcomings are often overlooked in early releases as the cutting edge …

A fundamental issue arising in mobile ad hoc networks (MANETs) is the selection of the
optimal path between any two nodes. A method that has been advocated to improve routing …

In position-based routing protocols, each node periodically transmits a short hello message
(called beacon) to announce its presence and position. Receiving nodes list all known …

An analytical approach to the characterization of energy consumption of large-scale wireless
networks is presented. The radio model includes energy consumption of nodes at various …

A multihop ad hoc network with mobile elements is considered. A model is created and
analytic expressions derived to characterize the statistics for link lifetime, new link interarrival …

We have observed a large positive quasiclassical magnetoresistance (MR) in a high mobility
two-dimensional electron gas in an AlGaAs∕ GaAs heterostructure. The magnetoresistance …

The fact that ad hoc networks are required to support mobility of individual network nodes
results in problems arising when routing data. These problems include route loss, poor …
