Embedded systems and sensors in wireless networks

Embedded systems are often distributed and deployed in various environments. Wireless sensor nodes deposited in various places provide light, temperature, humidity, and other measurements. Wireless nodes attached to circuits or appliances sense the current or control the usage. Wireless sensor networks are application-specific. Because of this they have to involve both software and hardware. They also use protocols, which relate to both the application and wireless network. The applications using wireless sensor networks are the consumer devices supporting multimedia applications, for example, personal digital assistants, network computers, and mobile communication devices. Emerging embedded systems run multiple applications such as Web-browsers, audio and video communication applications. We describe design issues in wireless networks to support sensors and embedded systems communication and information processing.
