    摘要: A low-power method for media access control on a semi-linear sensor network with multiple sensor nodes, includes: sensing a channel after waking up from a sleep mode by an arbitrary transmission sensor node that has obtained data; and generating a long preamble including a number of element preambles and sending to a destination sensor node after said channel sensing. This method further includes: sending said data to said destination sensor node after completion of transmission of said long preamble; and identifying duty cycle information of said destination sensor node after completion of transmission of said data and adjusting the number of said element preambles according to said duty cycle information.

    摘要: Provided are a communication method and apparatus of a wireless sensor network which uses at least one channel and has a tree structure. The method includes: generating windows, where a beacon interval is divided, according to each channel; selecting a window, which is not assigned to nodes that exist within a predetermined range from a certain node, from among the generated windows; and the certain node communicating with a child node of the certain node by using a channel to which the selected window belongs during a time corresponding to the selected window.

    摘要: Provided is a system and method for disseminating an accident. The accident dissemination system may include a sensor to sense the accident and to generate accident information; and a vehicle processor to open an S channel and thereby transmit the accident information to a vehicle at the rear entering an accident location where the accident has occurred, and to transmit the accident information to an oncoming vehicle, travelling in the opposite direction and being alienated from the accident location, via a first D channel opened by the oncoming vehicle.
