Wireless sensor networks require lightweight routing tailored for sensor devices with severe memory, power, and cost constraints. Such lightweight protocols must also support mobility and fault tolerance. The Very Lightweight Mobile Multicast (VLM) system addresses these concerns, introducing multicast support into wireless sensor networks. In simulation and in a true implementation on hardware...

background with the growing interest in long bone distraction several types of distractors have been introduced; all have the same principle of an outer structure which acts like a scaffold and the distracting mechanism is a separate device which is mounted on this outer structure. objectives we have used a simple and very light weight external fixator we designed and discuss the results of dis...

The implementation of lightweight technology is great significance to save energy, reduce pollution and achieve sustainable development. Lightweight mainly includes the use materials, such as high strength steel, magnesium alloy, aluminum engineering plastics, composite materials), advanced production technology, laser tailor-welded plate hydraulic forming steel red-hot technology), structural ...

This paper proposes a simple terminology for understanding and dealing with two current phenomena; we suggest calling them heavyweight and lightweight IT. Heavyweight IT denotes the well-established knowledge regime of large systems, developing ever more sophisticated solutions through advanced integration. Lightweight IT is suggested as a term for the new knowledge regime of mobile apps, senso...
