The proliferation of 'smart' energy management applications and the abundance of inexpensive, standards-based wireless MCUs are stimulating the growth of wireless sensor networks (WSN) across diverse markets, including home and building automation, telemedicine, and lighting.
WSNs provide a simple, economic approach for the deployment of distributed monitor and control devices, avoiding the expensive retrofit necessary in wired systems.A wireless sensor network is a collection of small randomly dispersed devices that provide three essential functions; the ability to monitor physical and environmental conditions often in real time, such as temperature, pressure, light and humidity; the ability to operate devices such as switches, motors; and the ability to provide efficient, reliable communications via a wireless network.
A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to monitor physical or environmental conditions. A WSN system incorporates a gateway that provides wireless connectivity back to the wired world and distributed nodes.WSNs are typically self-organizing and self-healing. Self –organizing networks allow a new node to automatically join the network without the need for manual intervention. Self-healing networks allow nodes to reconfigure their link associations and find alternative pathways around failed or powered-down nodes.
