Adaptive Correctness Monitoring for Wireless Sensor Networks Using Hierarchical Distributed Run-Time Invariant Checking

Tags:
monitoring systems

Overview This paper presents a hierarchical approach for detecting faults in Wireless Sensor Networks (WSNs) after they have been deployed. The developers of WSNs can specify "Invariants" that must be satisfied by the WSNs. It presents a framework, Hierarchical SEnsor Network Debugging (H- SEND), for lightweight checking of invariants. H-SEND is able to detect a large class of faults in data gathering WSNs and leverages the existing message flow in the network by buffering and piggybacking messages. H-SEND checks as closely to the source of a fault as possible, pinpointing the fault quickly and efficiently in terms of additional network traffic. Therefore, H-SEND is suited to bandwidth or communication energy constrained networks.

Why virus hoaxes are no joke

No anti-virus software will detect hoaxes because they aren't viruses. End users are trying to be helpful when they are forwarding these messages and they want to be the first ones to alert everyone," he said.

Fly me to the moon (and let us email round the stars)

The advances in microspacecraft and autonomous sensor technology suggest there might be thousands or even hundreds of thousands of communicating devices out there by the latter part of this century," said NASA's Burleigh.

Wi-Fi gets a sense of direction

The scientists, led by Professor Roger Green, assert that the device is 100 times more efficient at gathering in a signal than any previous optical sensor of this kind. But this new antenna is so precise, according to the researchers, that it can...

Smart carpet can spot fires, steer feet and sell beer

After being fitted to a floor and hooked up to a power source and a computer, the electronic carpet becomes "aware" of the position of each sensor chip, said the chipmaker. The textile contains a weave of conductive fibre studded with sensor chips...

Peter Cochrane's Uncommon Sense: The right technology for the right job

Switching transients on power grids with generators going on and off line, dynamic load sharing, fault and maintenance work, all induces massive transients that also swamp data signals. By reciprocity they also suck in energy from every local radio...

IP over everything?

SDH provides the reliability of circuit-switched pathways and resiliency should there be a fault but it is overly complex and not nearly as flexible as a native IP architecture when it comes to supporting Ethernet services, for example.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.

IBM Information Server Change Data Capture

In today's fast-paced world, access to real-time data has never been more important. To be successful, organizations need to be able to report and analyze corporate data quickly and easily, regardless of what applications created the data, what platform they're running on, or what database they're stored in.
