Wireless Personal Area Networks (WPANs) are an emerging technology for future short range indoor and outdoor multimedia and data centric applications. In this paper the authors' work in modeling and performance assessment of the operation of the 802.15.4 MAC layer, they have identified a number of issues that enhanced the performance of WPAN when compared to 802.11 Standards. The bridging function automatically created in the 802.15 standard but not in 802.11 standards because sensing nodes created in 802.15 standards. The 802.15 is performed by the coordinator of the source Node, which periodically visits the child nodes as an ordinary node.
