Sensor Networks : Information Acquisition and Routing System

Abstract

This article fits into development of an original embedded system. It introduces the design, specification, and realization of a wireless node sensor network in embedded FPGA architecture. This node will allow the construction of autonomous mobile network units which can move in unknowns, inaccessible or hostile areas for human being in order to collect environmental data by various sensors and transmits them by routing to a unit of distant process. For that, we have first developed and implemented IPs acquisitions which permits the measure of some grandeur like temperature, humidity and/or monoxide of carbon CO... Then we have integrated the routing module based on the OLSR proactive protocol in the Co-design platform. Real tests in network sensor of variable topology have been carried out and have permitted working node validation.
