Facilitating the configuration of protocol parameters , optimization of protocol operations , and more exact estimation of protocol performance , etc . basing on combinatorial theory and asymptotic method , we analyzed the properties of manets with nodes uniformly distributed in rectangular region . mathematical formulas of some basic properties of manets are obtained , such as the expected number of wireless links , mean node degree , the relation between network connectivity and radio range 因此本文第二章基于組合學方法和極限思想研究了矩形區域內節點均勻分布的無線自組網的幾項基本屬性,網絡中鏈路總數的期望值,網絡中節點度數分布情況,以及網絡連通性與無線信號傳輸半徑的關系等,得出了其解析描述。
