IEEE WCNC is the world premier wireless event that brings together industry professionals, academics, and individuals from government agencies and other institutions to exchange information and ideas on the advancement of wireless communications and networking technology. The 2012 edition of this conference was held in Paris, France, on 1 to 4 April 2012. The paper “Dynamic Frequency Allocation and Network Reconfiguration on Relay Based Cellular Network” worked by Dr.Haibo Mei, Dr. John Bigham and Dr. Peng Jiang was accepted in the Mobile and Wireless Networks Program of this conference. The abstract of this paper is in Appendix1.
During the conference trip,it was exciting to meet lots of outstanding researchers and developers in wireless communication field. There were numbers of key note speeches and presentation sessions. The author received some valuable comments during the presentation. All these experiences help authors’ further research in the wireless communication filed. Especially, the works “On Fractional Frequency Reuse in Imperfect Cellular Grids”, “Energy-Efficient Subchannel Allocation Scheme Based on Adaptive Base Station Cooperation in Downlink Cellular Networks”, “Optimized Dual Relay Deployment for LTE-Advanced Cellular Systems” are mostly interesting to the author.
This conference trip is valuable. It is always fantastic to have such chance to exchange idea with other researchers.
Abstract—Relay Based Cellular Networks (RBCNs) are a key development in cellular networking technology. However, because of ever increasing demand and base station failure, RBCNs still suffer from user congestion and low resilience problems. This paper proposes two competing solutions: dynamic frequency allocation and antenna tilting to those problems. Firstly a new dynamic fractional frequency allocation algorithm and a heuristic antenna tilting algorithm are designed. The comparative benefits of each algorithm are investigated. Secondly, the additional benefits of applying the two algorithms sequentially or iteratively are evaluated. The benefits of iteratively integrating the two algorithms are more interesting. Such integration solution allows the two algorithms to be applied cooperatively. The evaluations are based on high demand scenarios and base station failure scenarios. The results show that for the high demand scenarios the new dynamic fractional frequency allocation algorithm is very powerful, and the advantage of antenna tilting is not large though present. However, for the BS failure case there is a marked additional benefit in antenna tilting. The integrated solution achieves significantly more benefit than simple sequential application of the two algorithms.
