| dc.description.abstract | For the next generation network technology - Internet of Thing(IOT), which means everything in our daily life will connect to internet, for example: television, air conditioner, refrigerator, medicine equipment, and so on. Those of them hunger for network serving will cause an evolution to wireless network communication technology.
Adding more small cells, which are lower power, shorter coverage than the original Marco-cells in heterogeneous network architecture may be one of solutions to fulfill those requirements. However, numerous small cells will form a cluster, and they may cause additional problem to each member, i.e. the interference. The inter-cell interference coordinated(ICIC) was used to eliminate interference among Marco-cells in the 3GPP specifications of Release 8 about LTE can be adapted to release the interference problem. It is easy to understand and achieve, but its system resources utilization isn′t as same as we want. We dedicate ourselves to search for another possibility.
In this dissertation, we try to apply auction theory′s concept into addressing the interference among a cluster of small cells. We will propose an algorithm based on sealed-bid first price auction. In this auction algorithm, those of small cells can fight for system resource based on their channel quality. We hope the outcome is that system resource will be used by the best-fit base station, then that is why system throughput in auction algorithm is much higher than ICIC resolution.
Although the former auction algorithm gets high performance, we find that there are some small cell eNodeBs can′t grasp any resource during the auction in some conditions. The unfair defeat comes from the similar wanting resource and the small cell base station is not outstanding. These problem is the opportunity to make us to change our idea. We dramatic modify our algorithm, the distributed auction algorithm, which is based on English auction and erase the auction judge in new version. Concept of holding fairness is introduced in small cells′ bid process, it means that if one of small cell in the cluster doesn′t get enough resource in this auction, it will be assigned more power to compete for resource in the next auction. Distributed auction algorithm not only keeps advantages of the high system throughput compared to that of the former auction algorithm, but also delete the unfair issue.
