Ac 2009-360: Evaluation of Ieee 802.15.4 for Use in Smart Home Medical Care
نویسنده
چکیده
The IEEE 802.15.4 wireless standard has been identified as a potential candidate to be used in smart home medical care. This undergraduate research project evaluates the performance of IEEE 802.15.4 under interference from other wireless devices that operate in the same frequency band. Specifically, we focus on two very common wireless interfering systems in typical home environments: IEEE 802.11 WLANs and microwave ovens. The measurement results give a rough indication about the mutual interference of different systems and showcase the challenges of utilizing IEEE 802.15.4 for smart home medical applications.

متن کاملAn Energy Efficient Clustering Method using Bat Algorithm and Mobile Sink in Wireless Sensor Networks
Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...
