Wireless Sensor Networks are widely used in today's world in several applications ranging from environmental and health monitoring to military uses. Data Collection is one of the most important aspects of WSN and this topic has witnessed significant amount of research over the year. Traditionally static sensors were used in the data gathering process but later on mobile nodes were introduced with...
With the development of MEMS technology, mobile sensor networks are becoming an active research area, in which the design of sensor network node is an important issue. In this paper, the hardware design of a novel mobile sensor node is introduced, which is based on the mobile robot vehicle with ZigBee wireless communication module, high-performance DSP processor, and low-cost, low-power sensors. And...
FrontlineSMS and Ushahidi are both free and open source tools which allow for the collection, dissemination and visualization of data collected to and from the field. This paper outlines details of live demonstrations of the tools at the ICTD 2009 conference in Qatar.
The traditional Wireless Sensor Network (WSN) with fixed nodes canpsilat server the newly demand any more. For adapting to the future sensor network, we proposed a novel Multi-tier mobile network architecture; studied the problems of instability of network and high-fraction of event loss caused by the mobility of tiered nodes and mobile Fusion (F) node routes for data collection. For computing mobile...
