Cognitive Wireless Sensor Network Device for AAL Scenarios

Cognitive Networks appear as solution to avoid AAL scenarios problems like wireless interferences, secure a reliable communications, power consumption or different Quality of Service application needs. In this paper a prototype for Cognitive Wireless Sensor Networks is presented. This node is a hardware solution that will help to overcome problems in AAL Sensors Networks. The prototype, with three different radio interfaces, is looking for creating a network which can auto-optimize communications in real time related to different application needs. This solution allows developers to implement new applications and services for AAL scenarios.
