MULTI-HOP WIRELESS NETWORK SYSTEM
First Claim
1. A multi-hop wireless network system, comprising:
- a first radio device as the source;
a second radio device (M8) as the destination;
a third radio device relaying wireless communications between the first and the second radio devices; and
a radio controller allowing or rejecting a quality maintenance request according to characteristics of a wireless communication path running from the first radio device to the second radio device through the third radio device, the quality maintenance request requesting transmission of traffic with a certain level of quality, the traffic being a stream of packets transmitted from the first radio device to the second radio device;
whereinthe first and the third radio devices measure characteristics of the wireless communication path,the radio controller receives the measured characteristics of the wireless communication path and allows or rejects the quality maintenance request according to the received characteristics of the wireless communication path, andthe first radio device starts to transmit the traffic to the second radio device through the third radio device if the quality maintenance request is allowed by the radio controller.

Abstract
A source terminal measures characteristics of the path at the source terminal itself, produces a characteristics-measurement packet, and transmits the produced characteristics-measurement packet to a relay terminal. Upon receiving the characteristics-measurement packet, the relay terminal measures characteristics of the path at the relay terminal itself, renews the characteristics of the path included in the characteristics-measurement packet using the measured characteristics of the path, and transmits the characteristics of the wireless communication path to the destination terminal. The source terminal produces an admission-request packet and transmits the packet to the destination terminal. Upon receiving the admission-request packet, the destination terminal allows or rejects the traffic quality maintenance request according to the characteristics of the wireless communication path. The allowance or rejection of the quality maintenance request is transmitted to the source terminal with the admission-reply packet by the destination terminal.
