Design and implementation of a robust wireless sensor network

This paper presents the design and implementation of a novel wireless sensor network system using the device Freescale MC1321X. The proposed network management system consists of two different modules: the first one performs network formation and maintenance under a policy of power consumption reduction, and the second one measures and collects sensory data over the built backbone. In the case of the network formation, a distributed algorithm based on a self-organization strategy is used. Then, the second module algorithm implements a sensor management information system to collect information about minimal, maximal, and average temperatures. For this, the system module first builds a tree using a given sink over the formed network. Then, it performs the tasks of measurement, processing, and transmission to the sink node. Finally, the experiments, which have been performed under different scenarios in open and closed environments, have provided enough information to demonstrate the advantages regarding low energy consumption, reorganization and reliability of the proposed wireless sensor network system.
