| Abstract | In this thesis, we discuss novel resource management scenario for both macrocell and femtocell uplink transmission in OFDMA (orthogonal frequency division multiple access) and CDMA (code division multiple access) based femtocell networks. The research conducted up to now mainly focus on optimizing one of the layouts: femtocell or macrocell, by assuming other network resource distribution are known system parameters. Here we are jointly optimizing macrocell and femtocell resources by maintaining target SINR (signal to interference plus noise ratio) for each user. Therefore, this cooperative approach provides more reliable solution than the other non-cooperative approaches. Game theory concept is used as a basis of the resource allocation algorithm. In the CDMA based network, we use an energy based utility function with linear pricing scheme. Further, the effect of mobility is analyzed with the consideration of closed access and open access scenarios. The geographic-based channel allocation method is introduced to mitigate the interference between users in the OFDMA network structure. Further, the optimal channel is decided based on the normalized channel gain. The utility function is a capacity based efficiency function with a linear pricing scheme with the user power. The detail proofs are provided to verify the optimality of the system. |
