Analysis of Interference for a Multi-Radio Channel Assignment Algorithm
نویسندگان
چکیده
Interference is an important parameter that affects the performance of a network. By reducing interference, the capacity of the network is improved and this leads to an increased efficiency in communication. In this paper we analyze the interference of a robust channel assignment algorithm for multi-radio networks. This study is an extension to a previous work in which a channel assignment algorithm that is robust to the presence of primary users was introduced. The previous study was mainly focused on balanced assignment for the robust algorithm, i.e. assigning channels to radios such that all channels are equally distributed in the network. In this paper we give recommendations regarding the most efficient parameters to choose for the algorithm based on the analysis of interference. keywords: channel assignment, interference analysis, multi-radio network, primary user, energy efficiency
