Based on backoff stages the collided nodes stay,this paper classifies collisions into two categories:cross collision and intra collision,and then proves by analysis that cross collision is pervasive in networks,which is verified later by simulation results.

This paper, by employing the method of dialectical analysis, systematically elaborates on class conflict, political development conflict, the functional orientation and development process of political conflict as well as the framework design of eliminating the political conflict, etc.
