The Zigbee communication, based on PHY and MAC of IEEE 802.15.4 standards, is a communication technology to connect local wireless nodes and provides high stability and transfer rate due to data communication with low power. Zigbee is commonly organized with one coordinator and more than one node, as the basic service area and this network is referred to as PAN. In the nodes away from coordinator in one PAN, the signal strength is weak causing the network a shortage of low performance and inefficient use of resources due to transferring delay and increasing delay time and thus cannot conduct seamless communication. This study suggests the grouping method, that makes it possible to perform wide range data transferring depending on the node signal strength in Zigbee node and analyzes the suggested algorithm through simulation.
