연 구 분 야 Computer Networks & Internet Technologies
In information technology, a network is a series of points or nodes interconnected by communication paths. Networks can interconnect with other networks and contain subnetworks. A given network can be characterized by the type of data transmission technology in use on it(for example, a TCP/IP or SNA network); by whether it carries voice, data, or both kinds of signals; by who can use the network(public or private); by the usual nature of its connections(dial-up or switched, dedicated or nonswitched, or virtual connections); and by the types of physical links(for example, optical fiber, coaxial cable, and copper wire). Interests are focused on interconnection network for multiprocessor system and Internet. They include such topics as the design, implementation and management of high speed networks and multimedia load-balancing for the Internet.

Wireless Sensor Networks
A wireless sensor network (WSN) is a network made of numerous small independent sensor nodes. The sensor nodes, typically the size of a 35 mm film canister, are self-contained units consisting of a battery, radio, sensors, and a minimal amount of on-board computing power. The nodes self-organize their networks, rather than having a pre-programmed network topology. Because of the limited electrical power available, nodes are built with power conservation in mind, and generally spend large amounts.

ZigBee and Wireless Control
There are a multitude of standards like Bluetooth and WiFi that address mid to high data rates for voice, PC LANs, video, etc. However, up till now there hasn't been a wireless network standard that meets the unique needs of sensors and control devices. Sensors and controls don't need high bandwidth but they do need low latency and very low energy consumption for long battery lives and for large device arrays.
