摘要:
A method for providing traffic information includes registering a schedule containing the request details of a request for traffic information, receiving real-time traffic data for a time duration in advance of a traffic information provision time, and creating traffic information using the real-time traffic data at the traffic information provision time, and providing the traffic information. A related apparatus is also provided. The traffic information providing method and apparatus reduces an initial waiting duration for the provision of real-time traffic information.

A traffic information providing method and apparatus. The traffic information providing a method and apparatus provides for collecting real-time traffic information and supplementary information; broadcasting the collected real-time traffic information; storing the collected supplementary information in a supplementary information database; receiving a supplementary information request from a user who confirms the broadcast real-time traffic information; searching supplementary information corresponding to the received supplementary information request; and delivering the searched supplementary information to the user. In accordance with user requests, traffic information services differentiated among the users can be delivered. A benefit can also be realized among traffic information service providers, mobile network operators and the users.
摘要:
Provided is a method of dynamically reallocating a thread stack in a multi-threaded operating system, and more particularly, a method of dynamically allocating a thread stack of a multi-threaded operating system in an embedded system for wireless sensor nodes. The method includes the steps of: measuring sizes of data and non-data sections of a stack with respect to each thread; determining a new size of the non-data section of each stack based on the size of the data section of the stack measured with respect to each thread; and adjusting the size of the non-data section of each stack to the determined new size. According to the method, even without the source code analysis, an amount of memory spaces to be used can be reduced compared to that of a conventional static stack allocation method.
