|Title:||DISTRIBUTED PROCESSING IN WIRELESS SENSOR NETWORK USING FOR THE AUTOMATIC MONITORING AND WARNING SYSTEMS|
|Authors:||Nguyễn Văn Đại|
|Abstract:||Wireless sensor networks have received Significant attention in the last decade owing to their widespread use not only in monitoring the physical world but also in surveillance. Distributed processing applications in wireless sensor networks need to consider resource constraints. With high energy cost for wireless communications, application algorithms should be designed to reduce communication cost. Sensor readings are highly correlated spatially and temporally; furthermore, this correlation is extended to multi-modality sensor readings. Effective exploitation of these correlations can reduce data communication cost significantly. In most sensor applications, events are not happening in a consecutive manner; therefore, it is a waste of energy to keep nodes active for periods when no events are happening. In this project, we investigated energy efficiency and power awareness in wireless sensor networks. We have devised signal processing algorithms and networking protocols to support energy efficient operations in wireless sensor networks and have verified the effectiveness and energy efficiency of these algorithms and protocols using field data sets and experiments.|
