Abstract
The wireless personal area network (WPAN) is an emerging wireless technology for future short range indoor and outdoor communication applications. The IEEE 802.15.3 medium access control (MAC) is proposed to coordinate the access to the wireless medium among the competing devices, especially for short range and high data rate applications in home networks. In this paper we use analytical modeling to study the performance analysis of WPAN (IEEE 802.15.3) MAC in terms of throughput, efficient bandwidth utilization, and delay with various ACK policies under error channel condition. This allows us to introduce a K-Dly-ACK-AGG policy, payload size adjustment mechanism, and Improved Backoff algorithm to improve the performance of the WPAN MAC. Performance evaluation results demonstrate the impact of our improvements on network capacity. Moreover, these results can be very useful to WPAN application designers and protocol architects to easily and correctly implement WPAN for home networking.

There is an increased need for high data rate wireless multimedia services such as uncompressed high-definition television (HDTV), instantaneous music, data, and video file transmissionSensors 2010, 10 for both personal and home networking purposes
The IEEE 802.15.3 task group has been working on a promising standard including both medium access control (MAC) and physical layer (PHY), to realize short range and high data rate (1 Gbps or above) applications in wireless personal area network (WPAN)
In the WPAN MAC, the channel time request command should be successfully transmitted between a node and the Piconet Network Controller (PNC) to realize the communication during channel time allocations (CTAs)
Summary
There is an increased need for high data rate wireless multimedia services such as uncompressed high-definition television (HDTV), instantaneous music, data, and video file transmission. Sensors 2010, 10 for both personal and home networking purposes For this purpose, the IEEE 802.15.3 task group has been working on a promising standard including both medium access control (MAC) and physical layer (PHY), to realize short range and high data rate (1 Gbps or above) applications in WPAN. IEEE 802.15.3 standard defines three types of acknowledgment mechanisms for CTAs and CAPs as follows: No-ACK: In No-ACK (No-Acknowledgement) mechanism, ACK is not sent after a reception of message This mechanism is useful for only high data rate applications where guaranteed delivery is not required or acknowledgement is handled by higher layers or by some other mechanism. To introduce a Dly-ACK-AGG policy to improve the performance of WPANs. To apply payload size adjustment mechanism to improve the WPAN MAC under error channel conditions.
