Abstract: A node structure of a multiway search tree can accelerates a search speed by making a key, a key pointer and a node pointer coincident with the size of a cache line through the use of only one pointer written on a node regardless of the number of keys used in the node and, thereafter, reduce the main memory capacity, a search method using the node structure and a computer readable recording medium in which a program implementing the search method is recorded. The method for generating nodes of a multiway search tree includes the steps of: a) assigning at least one key to each of the nodes; and b) assigning pointer information so that related information written on the node is accommodated in a cache line regardless a number of keys.

Abstract: To track the location of a terminal in an indoor space by using a pseudo GPS signal transmitter, a GPS signal sent from an artificial satellite is received, and a clock signal of the artificial satellite is extracted from the received GPS signal to perform synchronization with the artificial satellite. Once synchronization with the artificial satellite is performed, a pseudo GPS signal is generated, and the transmission time of the pseudo GPS signal is controlled. The GPS signal is sent to the terminal located in the indoor space by a plurality of transmitting antennas based on the controlled transmission time, thereby enabling the terminal located in the indoor space to track its location.
