Abstract:
A method for making a mobile station receive a communication service is provided to allow the mobile station to receive the communication service from at least two base stations cooperatively, thereby improving a communication performance of the mobile station. Signals are received from at least two base stations(301). Signal strengths of the base stations are measured. An expected transmission rate of a mobile station is estimated. If the expected transmission rate is less than a predetermined standard, at least two base stations are selected according to a signal strength order(307). Information of the selected base stations and channel state information are transmitted to a base station, which is providing or receiving a communication service to the mobile station(309). Powers and resources are allocated from the selected base stations(311). A signal transmission and reception process is performed between the mobile station and the selected base stations by using the allocated powers and resources(313).
Abstract:
PURPOSE: A system for generating deduction tree in an image sensor network and a method thereof are provided to generate deduction tree for effectively merging image sensor data. CONSTITUTION: A cluster forming module(31) comprises a cluster by binding image sensors which a watch overlaps of the image sensors. The cluster forming module expresses image sensors which are composed of the cluster as a node. The cluster forming module comprises correlation of a watch between two image sensors, as graph structure expressed by weighting of a connection link between two nodes An initial tree forming module(32) comprises the graph structure as initial tree minimized a depth of tree.
