VANET Channel Allocation Scheme Based on Hungarian Algorithm

With the development of vehicle network services and related software, the dedicated short-range communication (DSRC) frequency band is not sufficient to carry the increased wireless service demand in the in-vehicle network. The large television spectrum (i.e., the TV white space spectrum) issued by the US Federal Communications Commission for cognitive access will be used to provide additional bandwidth to the in-vehicle network, and the effective channel allocation scheme for TV White Space (TVWS) has become our goal. In this paper, we design a channel allocation scheme based on the Hungarian algorithm. Our main goal is to increase network throughput while minimizing network latency. We present simulation schemes and numerical evaluations to illustrate the desired performance of the proposed channel allocation scheme.
