    Abstract: PURPOSE: A method for supporting a vehicle communication handover is provided to perform a stable media access based on contention free through a WPCF(WAVE Point Coordination Function) channel access method. CONSTITUTION: A first RSU(Roadside Unit)(100a) receives vehicle information from a first vehicle(200a) which newly enters into a coverage of the first RSU. The first RSU transfers the channel access sequence to the first vehicle. If the first vehicle request a handover, the first RSU transfers the handover information about the first vehicle to a second RSU through a WAVE handover control unit. The second RSU receives the vehicle information from the first vehicle. According to the vehicle information, the second RSU allocates the vehicle access order.

    Abstract: PURPOSE: A transmission scheduling apparatus in a wireless multiple hop network and method thereof are provided to solve packet overload problems in a specific node by allocating differentiated time slots to a scheduling table according to the calculated transmission demand. CONSTITUTION: A transmission scheduling apparatus initializes scheduling variables which are necessary to schedule the transmission of nodes in a wireless multiple hop network(S410). The transmission scheduling apparatus calculates the transmission demand of all nodes(S420). The transmission scheduling apparatus converts the calculated transmission demand into the number of guaranteed time slots(S430). The transmission scheduling apparatus allocates the time slot to the nodes(S440).

    Abstract: PURPOSE: An apparatus and a method for vehicle communication handover support are provided to embody a stable media access based on contention free with the access method of a WPCF(WAVE Point Coordination Function) channel in handover. CONSTITUTION: A first RSU(Roadside Unit)(100a) receives vehicle information from a first vehicle(200a) which newly enters into. The first RSU transfers a channel connection order to the first vehicle. The first RSU transfers handover information about the first vehicle through a WAVE handover controller(310) to a second RSU(100b). The second RSU receives the vehicle information from the first vehicle. The second RSU transfers the channel connection order to the first vehicle.
