... The throughput performance for the scheme without using priority. the AP becomes the bottleneck for the communications in IEEE 802.11. For the scheme without cooperation, we fix the resource allocation ... applications. Furthermore, by adjusting the parameter r, we were able to dynamically adjust the resource allocation between the IEEE 802.16 and the IEEE 802.11....

... distance between the center of the sub- cell and the BS 1 is less than 0.5R c . Moreover, if the sub- cell approaches further to the BS, the result is degenerated and gets even worse than the case with ... The reason is that, in this case, the BS allocates a special portion of its power to the relay, which has a tiny role in supporting the users that are close to the B...
