Wireless communication apparatus and method using an adaptive credit redistribution algorithm

A Bluetooth wireless communication apparatus connected to a plurality of piconets and operating in a scatter mode, comprising:

• a buffer unit for storing credit values by link for the plurality of piconets, and the total sum of the respective credit values of links as a temporary account value;
• a communication priority decision unit for updating the credit values by link and the temporary account value every slot based on a predetermined manner, and selecting a link to perform communications based on a comparison result of the credit values by link at each Presence Point(PP);
• a credit redistribution unit for unevenly redistributing predetermined credit values based on respective characteristics of links in one of the two cases in which the communications are interrupted with a POLL_NULL sequence and the temporary account value becomes the same as the total number, n, of links;
• and
• a communication initiation unit for initiating communications through a corresponding link selected in the communication priority decision unit.
