| Abstract: | A utility based network selection scheme having been formerly proposed by us was explained and analysed furtherly. Different from a traditional scheme only considering two factors, our scheme took more factors important for multimedia application in future urban road heterogeneous wireless access networks into account within a simple framework. The selection algorithm was improved and a rudimental simulator was developed. |
