Flash memory is the most prevalent storage medium found on modern wireless sensor devices (WSDs). In this article we present two external memory index structures for the efficient retrieval of records stored on the local ...

Wireless data broadcasting is an efficient, bandwidth preserving way of data dissemination. However, as the amount of data increases, the waiting time of the clients becomes unacceptably high. The present paper proposes ...

The coordination paradigm has been used extensively as a mechanism for software composition and integration. However, little work has been done for the cases where the software components involved have real-time requirements. ...

Data dissemination via periodic broadcasting considers a set of items, each with a given request probability, size and scheduling cost. The goal is to construct a broadcast schedule that minimizes the mean query serving ...

The purpose of this paper is to investigate the use of a new concept in component communication, expressed by the channel based coordination language called ρέω, in the coordination of Web Services. The role of ρέω is to ...

In this paper we present a new queue length based Internet congestion control protocol which is shown through simulations to work effectively. The control objective is to regulate the queue size at each link so that it ...

Nanonetworks comprise numerous wireless nodes, assembled at micro-to-nano scale. The unique manufacturing challenges and cost considerations of these networks make for minimal complexity solutions at all network layers. ...

In this demo, we present an efficient hybrid indoor positioning solution that uses multi-sensory location-oriented observations, including WiFi, accelerometer, gyroscope and digital compass data, that are widely available ...

We present an example-based crowd simulation technique. Most crowd simulation techniques assume that the behavior exhibited by each person in the crowd can be defined by a restricted set of rules. This assumption limits ...
