In this paper the development of a Mobile Health monitoring system is described. The system combines user location data with air quality information provided by a heterogeneous sensing infrastructure providing users with advises about their daily exposure to air pollutants. The highly dynamic integration of different kind of nodes, mostly characterized by rather constrained resources, of this a...

Data storage has become an important issue in wireless Sensor Networks (WSN) as a huge amount of collected data needed to be archived for future reference. Storage nodes are introduced here to store the data collected from the sensors in their proximities. The storage nodes alleviate the heavy load of transmitting all data to a central place for archiving and reducing the communication cost ind...

Sensor networks are deployed for various monitoring applications. The reporting should be in secure manner so that the adversary can’t forge the data and can be prevented from any disclosure. In this paper we have identified those calculations which are not necessary to be performed on sensor node for securing the network, shifted to base stations to save the energy at nodes. Using pre-processi...

A wireless sensor network consists of sensor nodes deployed over a geographical area for monitoring physical phenomena like temperature, humidity, vibrations, seismic events, and so on. Typically, a sensor node is a tiny device that includes three basic components: a sensing subsystem for data acquisition from the physical surrounding environment, a processing subsystem for local data processin...

Wireless sensor network refers to a group of sensors, linked by a wireless medium to perform distributed sensing task. The primary interest is their capability in monitoring the physical environment through the deployment of numerous tiny, intelligent, wireless networked sensor nodes. Our interest consists of a sensor network, which includes a few specialized nodes called processing elements th...

—An interplay between mobile devices and static sensor nodes is envisioned in the near future. This will enable a heterogeneous design space that can offset the stringent resource and power constraints encountered in traditional static sensor networks by taking advantage of the more powerful mobile devices. We present a systematic framework for end-to-end query processing, using a two-layer arc...

One of the important problems in parallel computing is the mapping of the parallel algorithm to the parallel computing platform. Hereby, for each parallel node the corresponding code for the parallel nodes must be implemented. For platforms with a limited number of processing nodes this can be done manually. However, in case the parallel computing platform consists of hundreds of thousands of p...

High energy consumption is led due to the various IT infrastructures, electrical equipment and the randomness jobs will be present on the computing nodes. To handle with the randomness nature of the tasks, the computing nodes will be power on all the time because the jobs will be incoming in any of the time for processing, which leads to the high energy produced. This paper presented a proposed...
