Abstract: A position-based routing method by using a cell in a wireless sensor network is provided to minimize the energy and to determine a path until a destination node easily by reducing the periodical communication for the position information confirmation. In a next-hop position calculation process, the virtual ONI(Optimal Next-hop Information) among the paths until the destination node is calculated. In a communication area division process(302), the communication area is divided into fixed cell sizes by using the calculated virtual ONI position. In a packet broadcasting process(303), a packet including the virtual ONI position and the cell sizes is broadcasted to the surrounding node in the communication area. In a next-hop node decision process(305), the firstly transmitted surrounding node is determined as the next-hop node after receiving a response message in regard to the broadcasted packet from the surrounding node. In the next-hop position calculation process, the position joined by the virtual segment for connecting the distance until the destination node and a virtual circle corresponding to one's own communication area is calculated and the calculating result is determined as the next hop position.

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).
