A generalized routing reliability evaluating model for manet

Impact of nodes dynamically, randomly, frequently entering and leaving network on unreliable routing connection has been clearly described by a generalized routing reliability evaluating model according to measuring parameters of relative performance by studying on two-hop unit model presented in this paper. A new rate expression of node entering and leaving spindle region has been established by analyzing the two-hop unit model for MANET so as to obtain the closed solution of routing reliability. NS2-based simulating results validate the effectiveness and correctness. Routing reliability evaluating model proposed can be used to evaluate the reliability of communication link and can also be adopted to design MANET with given level of reliability.
