Research for Invulnerability of Ad hoc Network Topologies

Invulnerability is one of the most important properties of mobile Ad hoc networks topologies and has important effects on the finish of transmission tasks.First presents the definition,index and model of invulnerability of Ad hoc networks topologies,and points out the relationship between invulnerability of Ad hoc networks topologies and power control.Then summarizes current research progresses,along with analyses and comparisons,in two aspects,homogeneous power control and heterogeneous power control,respectively.At the same time,the defects of those efforts are clearly pointed out.At last,points out the shortages of current research and future research directions and trends.
