For design and maintenance of wireless network, node importance evaluation is a crucial issue. But if we evaluate it with single index, result may be unilateral. If we evaluate it with different indexes simultaneously, inconsistent of results may occur. To solve these problems, a compositive evaluation method based on radar chart is proposed as well as relevant evaluation indexes. With this method, evaluation indexes are showed graphically and node importance is evaluated from different viewpoints. In this way, a compositive evaluation result can be gotten according to the size of area shaped by connection of these index values in the chart. The Application of the proposed method is showed by an example case.
