Integrated access selection considering wired and wireless resources

Nowadays, it is easy to find that we are surrounded by a sea of dense wireless accesses including 3G, 4G and several WLANs, etc. Commonly, the process of selecting an appropriate access is manually operated by end users. Some researches have been brought out to influence selecting process of users for network optimization, such as load balancing, QoS, etc. But capacity of wired links, which is neglected in most previous methods, may become a constraint as wireless bandwidth grows drastically. In this paper, we propose an access selection mechanism considering both wireless radio resource and capacity of wired backhauls integrally. Data-driven evaluation shows that our integrated selection mechanism could improve the average wireless bandwidth for more than 90% of the mobile devices. At the same time, the standard deviation of traffic on the 7 under-observing wired links is 4.69, which is much lower than the value of 11.9 before applying the mechanism. The results reveal that our mechanism also make a balance use of wired backhaul links as well as optimize wireless performance.
