Radio Number of Complete Bipartite Graphs and even Cycles

With the continuous progress of wireless communication network technology, more and more users have formed a strong dependence on it, and also put forward higher requirements for the quality of network signal transmission. In wireless communication network, the channel plays a very important role. However, due to the limited channel resources in the communication network, the interference between channels is intensified, and the channel resources are not fully utilized. Therefore, it is very important to seek a reasonable and effective channel assignment strategy. In this paper, we study the network constructed by Cartesian product, and focus on the optimal channel assignment strategy for two sets of stations and even cycle networks under Cartesian product condition.
