Abstract: A communication method in an Ad-hoc network is provided to minimize energy used for assigning data bits to be transmitted to a secured channel. A communication method using an Ad-hoc network comprises the following steps of: setting up a negotiation channel between the first node and the second node for transmitting/receiving data and at least one data transmission channel; and detecting a common unavailable channel between the first node and the second node among the set data transmission channel; transmitting through the detected channel. The channel detection step comprises the following processes. The first node provides information about its unavailable channel to the second node through the negotiation channel, and then receives information about the common unavailable channel, which is obtained by comparison between provided information and information about an unavailable channel of the second node, from the second node.

Abstract: The present invention relates to a reflector antenna for tracking a mono-pulse for a manned/unmanned moving object which rapidly moves from a distance, and, more particularly, to a feeding position control device of a reflector antenna which is capable of changing a beam width and a tracking range of a mono-pulse. The apparatus of the present invention includes a reflector antenna for generating a sum signal by synthesizing a multi-beam pattern formed through four feeding antennae in a feeding unit; a mono-pulse reception unit for detecting the level of the generated sum signal; and a feeding position control unit for sequentially changing a position of the feeding unit according to the level variation of the sum signal relative to a reference level of the sum signal with the maximum separation distance. The feeding unit position control unit increases a beam width and a tracking level of the mono-pulse by changing the position of each feeding antenna if the level of the detected sum signal is greater than the reference level of the sum signal in case of the maximum separation distance.
