    摘要： A media access control method of a wireless sensor network (WSN) is provided. The media access control method includes first sensor nodes, existing in a non-overlapping area where clusters do not overlap, media-accessing with a Time Division Multiple Access (TDMA) method and communicating with a Cluster head (CH) in a first section. Further, and the method includes second sensor nodes, existing in an overlapping area where the clusters overlap, media-accessing with a contention-based method and communicating with the CH in a second section. Because communication between nodes of the non-overlapping area where the clusters do not overlap, uses a reservation-based TDMA method, collision between nodes can be prevented, and because communication between nodes of the overlapping area where the clusters overlap, uses a contention-based CSMA/CA method, interference between neighboring clusters can be prevented.

    摘要： A clustering method of a wireless sensor network is provided to minimize energy consumption. The clustering method includes the operations of determining a number of initial nodes within radio range of ordinary node, the ordinary nodes existing within radio range of a cluster head, and setting an ordinary node having a highest number of initial nodes among the ordinary nodes in the radio range of the cluster head, as a gateway. Because the number of usually large energy consuming cluster heads and gateways can be minimized, energy efficiency of wireless sensor network increases.

    摘要： An integer coding method supporting diverse frame sizes and a coder-decoder (CODEC) implementing the method are provided. Maximum sample values are detected from a plurality of frames having different numbers of samples. The detected maximum sample values are normalized on the basis of a maximum sample value of the largest frame. A maximum sample value is detected from the normalized sample values. Multiples are determined according to the size of each frame on the basis of the detected maximum sample value and a sample value of each frame is multiplied by the multiples to generate an integer code.
