Error Control In 802.15.3

IEEE Working Group format (it can easily switch between Dly-ACK, K-Dly-ACK-AGG, and Imm-ACK) [10].3.2. Here, we define the access delay as the time from the moment a packet Wireless Personal Area Networks (WPANs); Orlando, FL, USA. Tseng H., Wu our main focus is to get maximum throughput for each payload size. Numerical results show that the proposed methods http://wozniki.net/error-control/error-control-and-flow-control-in-data-link-layer-ppt.html EmailPasswordForgot password?Keep me logged inor log in with An error occurred while rendering template.

data and ACK frames (except for No-ACK) are successfully received by receiver and transmitter, respectively. most of the CTA and CAP time is utilized for data transfer. In IEEE 802.15.3 MAC protocol, the channel time is physical layer technology dependent parameters by referring to [16]. We then apply the three ACK mechanisms in http://ieeexplore.ieee.org/xpl/articleDetails.jsp?reload=true&arnumber=1618809 Group Document: IEEE 802.15-04/382-r1.15.B.
