Improved deployment of wireless sensor networks in the intelligent building

With the exponential growing of various applications, wireless sensor networks have attracted a great deal of interest in recent years. However, deploying wireless sensor networks into practical environments requires different deployment strategies owing to the complex application conditions. In this paper, a complete study for the implementation of wireless sensor networks in the intelligent building is presented. We carry out some experiments to study the characteristics on the environment of intelligent buildings before deploying the actual system. Several vital parameters of wireless sensor networks are measured, such as Package Loss Rate (PLR), Link Quality Indicator (LQI) and Round-Trip Time (RTT), and then, we analyze the details of the deployment scheme in the intelligent building based on the results of these tests. At the end of the paper, we propose an optimized deployment strategy of the system to improve the performance of the sensor networks. And several evaluation results show that the presented system can satisfy the requirements of the applications in the intelligent building.
