Abstract:

The coverage reliability is used to measure the capability of communicating during the moving of tactical Internet. First, both typical mobility characteristics and five kinds of tactical mobility patterns are proposed, which are based on the relationship between the cooperation of nodes and tactical tasks. Second, by studying the concept of coverage reliability of tactical Internet, the coverage reliability evaluation model and an improved Monte Carlo algorithm are presented on a basis of considering the tactical mobility patterns. Finally, simulations are executed to evaluate the different influences of mobility patterns to coverage reliability of tactical Internet. The results show that the proposed model and algorithm are effective.
