Abstract
With the increasing number of users and the complexity of services, only single communications network cannot meet its request in smart distribution grid(SDG).Therefore, heterogeneous network is an effective way to solve this situation. In this paper, a new approach of heterogeneous wireless network for SDG based on the chi-square distance is proposed and investigated. The algorithm firstly estimate weights of network attributes using analytic hierarchy process(AHP) according to different types of service which depends more on the consideration for the user side. Secondly, the CRITIC and anti-entropy weighting method are used to determine the objective weight according to the actual network parameters, and the final weight is obtained by the comprehensive weighting method based on the alignment minimization. Finally measure the chi-square distance from each candidate network to the ideal network, and the candidate network of smallest chi-square distance is the best access network.
