Abstract

In this paper, we proposed the new ZigBee APS layer. We added a few functions, ZigBee congestion control frame (ZCCF) and ZigBee time congestion control (ZTCC), to the current ZigBee to realize efficient data transmission. In the current ZigBee networks, they do not provide congestion control which is an essential issue in all networks. The congestion is an unavoidable problem refers to data transmission especially when the network traffic increases. The simulation result using network simulator -2 (NS2) demonstrates the validity of our proposed ZigBee APS layer.
