A Capacity Maximization and Spectrum Allocation Joint Algorithm on Specified Link

The channel capacity reflects the amount of information the channel can transmit. In particular environment, a specified link with maximum capacity is needed in order to satisfy the transmission requirements. In this paper, we propose a novel capacity maximization and spectrum allocation joint algorithm on specified link in a novel self-organized network model. First we construct an improved threshold matrix based on channel capacity. Then, based on the above matrix, we can get the specified link topology. According to the topology, we use KM algorithm to allocate the spectrum. At the same time, we ensure that the channel capacity of the specified link is maximal. We show the network results and spectrum allocation results in the topology. By the statistics, we get the network time and network success rate for different channel condition. Finally, simulation results present that the capacity maximization and spectrum allocation joint algorithm can get the satisfied network result.
