Wireless device which can improve stability in wireless communications and wireless network using the same

摘要

When wireless communications are made between a first wireless device and a second wireless device along a route, two wireless devices which exist between the first and second wireless devices each determine the lowest maximum transmission rate (11 Mbps) in the wireless intervals on the route from themselves to the second wireless device to be their own transmission rate txRate (11 Mbps) and two other wireless devices which exist between the first and second wireless devices each determine the lowest maximum transmission rate (54 Mbps) in the wireless intervals on the route from themselves to the second wireless device to be their own transmission rate txRate (54 Mbps).

主权项

1. A wireless device constituting an autonomously established wireless network in which a source wireless device makes multi-hop wireless communication with a destination wireless device, comprising:
a first communication control unit configured to determine, among n maximum transmission rates in n wireless intervals existent between the wireless device and the destination wireless device (n is equal to or more than 2), the lowest maximum transmission rate as the wireless device's transmission rate; a transmitting unit which transmits a packet at a transmission rate determined by the first communication control unit configured to determine transmission rate; and a second communication control unit configured to determine the n maximum transmission rates according to packet delivery performance indicating performance of packet delivery to wireless devices existent in the n wireless intervals, wherein the first communication control unit configured to determine the lowest maximum transmission rate among the n maximum transmission rates determined by the second communication control unit as the wireless device's transmission rate, and wherein the n wireless intervals include at least a wireless interval from the wireless device to another wireless device and a wireless interval from said another wireless device to the destination wireless device.
