Addressing Interference issues in a WSN based smart home for ambient assisted living

This study enlightens critical issue of ZigBee based smart home to design scalable, intelligent home environment for ambient assisted living (AAI). An intelligent monitoring system with industrial grade is significant for elder care or any individual who lives alone. Our primary focus is to improve the reliability and minimize data loss of communication due to interference and collision. By research efforts, the realization of goals of smart home in different possible urban conditions can be achieved. Providing idea and gain of a holistic methodology for reliable communication in sensor networks is also the objective of this research paper which can be attained by integrating, learning and using cognitive tactics at the physical layer. In order to evaluate RSSI, PSR and Interference in IEEE 802.14.4 ZigBee based wireless sensor and networks; the smart home setup is developed and implemented on real time applications. The results show that the distance, deployment environment and positioning of sensor nodes are key parameters that decide the reliability of wireless sensor and networks.
