Abstract(in English) | The demand of content distribution services via wireless local area networks (WLANs) has been in-creasing. Wireless multicast techniques are commonly used in these content distributing services, where many users simultaneously receive the same content, because they can efficiently use radio resources by using point-multipoint (PMP) transmission. Multicell networks consisting of WLAN access points (APs) are suitable for distributing content to many users in dedicated but wide areas. However, in wireless multicast, the design of effective loss compensation techniques remains an issue to be solved. Retransmission and multiple transmissions from APs are not effective in WLANs because no time-diversity effect is available in static environments. Another solution for the problem is data-frame relay by user terminals; a terminal that correctly received a data-frame relays to other failed terminals. In this paper, we propose a medium-access-control design for loss compensation using data-frame relay. In our method, data-frame relays are performed in the boarder area between neighboring cells, resulting in effective loss compensation for failed terminals near the boarder. In this paper, using computer simulations, we validate our method. |
