Wireless networks formed by peer devices or device-to-device communications are drawing more and more attention recently. In IEEE 802 Standardization Committee, TG15.8 was set up to develop a new standard for peer aware communication (PAC).

IEEE 802.15.4 is a current major technology for low- rate low-power wireless personal area networks (WPANs). To study the reliability of its medium access control (MAC) function, in this paper we evaluate its packet dropping rate performance with focus on the reason to drop a packet. Considering the compatibility with the original protocol, when the access failure happens the packet isn't dropped...
