Recognizing the needs and challenges facing NASA Earth Science for data input, manipulation and distribution, Mobitrum is proposing a ? Wireless Sensor Portal Technology? specifically for field personnel to send/receive digital and analog data from various sensors for data input, analysis and distribution purposes. The need for development of cooperative communications at distributed sensor network encompasses the design of portable wireless computing device, which in real-time send and receive digital and analog data from variety of sensors, provide effective initial field verification of data, and distribute the data to various nodes and servers at collection, processing and decision hub site. A Sensor Wireless Portal Technology is therefore needed for sensor communications at distributed and networked environments where the operations include multiple sensor data input, manipulation and distribution.
