Abstract

Currently, in addition to wireless LAN (WLAN), equipments for longer-distance wireless communication like IEEE 802.11af and 802.11ah are being developed. Thus, in the near future, access points (APs) and wireless stations (STAs) equipped with functions for both WLAN communication and longer-distance communication are expected. Although longer-distance communication enables STAs to connect to their APs even outside the WLAN coverages, the transmission rates are smaller. Multihop WLAN communication via relay STAs provides larger transmission rates. However, frame transmission from relay STAs increases collisions, and additional routing is required. This study proposes collision-protected multihop transmission without preliminary routing in the environment in which both WLAN communication and longer-distance communication are available. Collision protection and routing are processed by a two-way handshake between data frame transmitter and receiver stations with the longer-distance communication. After the handshake, the data frame is transmitted via relay STAs by exclusively using the WLAN channel.

远距离无线通信支持无线局域网通信的防碰撞多跳帧传输方法

目前，除了无线局域网(WLAN)之外，还在开发IEEE 802.11af和802.11ah等远距离无线通信设备。因此，在不久的将来，预计将出现既具有WLAN通信功能又具有较长距离通信功能的接入点(ap)和无线站(sta)。尽管长距离通信使sta能够在WLAN覆盖范围之外连接其ap，但传输速率较小。多跳无线局域网通信通过中继sta提供更大的传输速率。但是，来自中继sta的帧传输增加了冲突，并且需要额外的路由。本研究提出在WLAN通信和较长距离通信同时可用的环境下，不需要预先路由的防碰撞多跳传输。碰撞保护和路由由数据帧发送站和接收站之间的双向握手处理，具有较远的通信距离。握手后，数据帧通过中继sta通过专用的WLAN信道传输。
