摘　　要：分别在理想传播环境和阴影衰落环境下,假设节点采用均匀分布,采用网络覆盖的方法对移动Ad hoc网络的连通度进行了理论计算,得出了在一定覆盖范围内,网络连通度、节点数与节点发射功率三者间关系的理论公式,建立OPNET网络仿真模型,并通过Matlab仿真验证其正确性.Under the conditions of ideal and shadow fading environments,with the assumption that nodes are uniformly distributed,the connectivity of mobile Ad hoc networks（MANET） is calculated in theory respectively.The exact formulas of connectivity,which shows the relation of connectivity,node number and node transmitted power,are derived its validity has been verified by the Matlab simulation.Then,network simulation model is constructed based upon OPNET and the network performances further demonstrate the rationality of the theoretical analysis.
