In recent years, wireless sensor network (WSN), as a powerful tool, has been widely applied to structural health monitoring (SHM) due to its low cost of deployment. Several commercial hardware platforms of wireless sensor networks (WSN) have been developed and used for structural monitoring applications [1,2]. A typical design of a node includes a sensor board and a mote connected to it. Sensin...

We propose Mote Herding, a new system architecture for large scale, heterogeneous sensor networks. Mote herding uses a mix of many 8-bit sensor nodes (motes) and fewer but more powerful 32-bit sensor nodes (microservers). Mote herding groups motes into flocks that are connected via a multihop network to a microserver acting as a shepherd. Shepherds exploit their greater communications and compu...

An attractive architecture for sensor networks is to have the sensing devices mounted on small computers, called motes. Motes are battery-powered, and can communicate in a wireless fashion by broadcasting messages over radio frequency. In mote networks, the connectivity of a mote u can be defined by those motes that can receive messages from u with high probability and those motes from which u ...

In many distributed sensor applications such as studying bird migration patterns, it is necessary to track down and retrieve data from a specific mobile object tagged with sensors and radio transceivers. Because these objects are mobile and operate over a wide area, it is expensive and sometimes impossible to build a single wide-area sensor network that covers all areas of operations. During pe...

1 ABSTRACT: A risk monitoring of buildings for natural and man-made hazards mitigation is discussed in this paper. Ubiquitous monitoring using a network of wireless sensors is one of the most promising emerging technologies for this purpose. A smart sensor based on the “Berkeley Mote” platform was introduced, and application to the next generation of structural health monitoring and control was...

Sensors networks instrument the physical space using motes that run network embedded programs thus acquiring, processing, storing and transmitting sensor data. The motes commercially available today are large, costly and trade performance for flexibility and ease of programming. New generations of motes are promising to deliver significant improvements in terms of power consumption and price — ...

A wireless sensor network that employs passive radio wake-up of the sensor nodes can reduce the energy cost for unnecessary idle listening and communication overhead, extending the network lifetime. A passive wake-up radio is powered by the electromagnetic waves transmitted by a wake-up transmitter rather than a battery on the sensor node. However, this method of powering the wake-up radio resu...

We propose mote technology as a potential source for wireless communication of medical signals in body area networks. In order to determine if the proposed system is useful, a robustness metric is developed specifically for a biosensor shirt application. The objective is to provide a tool to evaluate whether the mote hardware will deliver acceptable performance given perturbations present in a ...
