Radio Resource Allocation on Complex 4G Wireless Cellular Networks

downlink radio resource allocation in cellular cdma/tdma networks: a novel heuristic algorithm

it is shown in [1] that the optimal downlink radio resource allocation for non-realtime traffic in cellular cdma/tdma networks can be mapped to a multi-dimensional multiple-choice knapsack problem (mmkp) which is np-hard. in this correspondence we propose a heuristic algorithm with polynomial time complexity for this problem. numerical results indicate significant computational performance impr...

Radio resource allocation in fixed broadband wireless networks

We consider use of fixed broadband wireless networks to provide packet services for telecommuting and Internet access. Each cell in such networks is divided into multiple sectors, each of them served by a sector antenna co-located with the base station (BS), and user terminals also use directional antennas mounted on the roof top of homes or small offices and pointed to their respective BS ante...

Radio Resource Allocation in Heterogeneous Wireless Networks Using Cooperative Games

Next generation wireless networks are expected to be heterogeneous consisting of several wireless technologies including, but not limited to, UMTS, GPRS, Satellite and WLAN networks. These networks provide bandwidths that range from tenth hundreds of Kbits/sec provided by technologies such as GPRS, to tens of Mbits/sec provided by Broadband wireless LANs such 802.11a. Here we study the problem ...

Dynamic Enhanced Radio Resource Allocation for Wireless Communication Networks

Mobility of the wireless user creates uncertainty in demand and non-optimum use of radio resources. Current wireless networks are periodically re-configured manually to improve network performance. These network reconfiguration and performance optimizations consume thousands of engineering hours and are often done by trial and error. However, the benefit of these efforts will be minimized as in...
