Direction finder, an important component of electronic warfare system, is a device that detects electromagnetic waves radiated from target radar and measures its angle of arrival. Compared to the phase-comparison method, the amplitude-comparison method has simpler system, and it's easy to miniaturize; however, relatively, its direction finding is less(More)
Wireless sensor networks has been evolving toward wireless sensor actuator networks (WSAN), which provide more dynamic services based on events from sensor nodes. Actuators in WSANs are very energy sensitive device since they usually consume more energy than sensor nodes. And usually WSANs are based on the event reliability to support more accurate(More)
This paper proposes the communication architecture for the Home Networking services and introduces a new Home Networking Control Protocol, Living network Control Protocol (LnCP) to connect the devices at home to communicate each other. LnCP is targeting a convenient and easy-to-use home networking system and basically provides controlling and monitoring the(More)
