A distributed virtual sensor scheme for marine fuel engines

A scalable interest management scheme for distributed virtual environments

With the expansion of the internet and its bandwidth, distributed virtual environment (DVE) applications have become more prevalent. In DVE applications, users frequently crowd in a specific place, and a key aspect to consider is how to provide interactive performance for users. However, existing approaches using multicast require users to receive uninteresting messages. Even though recent work...

A Less Intrusive System Monitoring Scheme for Distributed Virtual Environments

A Distributed Data Storage Scheme for Sensor Networks

We present a data storage scheme for sensor networks that achieves the targets of encryption and distributed storage simultaneously. We partition the data to be stored into numerous pieces such that at least a specific number of them have to be brought together to recreate the data. The procedure for creation of partitions does not use any encryption key and the pieces are implicitly secure. Th...

A distributed approximation scheme for sleep scheduling in sensor networks

We investigate the theoretical feasibility of near-optimal, distributed sleep scheduling in energyconstrained sensor networks with pairwise sensor redundancy. In this setting, an optimal sleep schedule is equivalent to an optimal fractional domatic partition of the associated redundancy graph. We present a set of realistic assumptions on the structure of the communication and redundancy relatio...

A Distributed Secured Localization Scheme for Wireless Sensor Networks

Enforcement of location-aware security policies requires trusted location information in localization of wireless sensor networks. In this paper, we propose to develop a distributed secured localization scheme that validates the reliability of location information associated with event reports. We make the network distributed by including a set of Anchor nodes across each route in the network. ...
