Invulnerability Assessment for Mobile Ad Hoc Networks

Usually, a mobile ad hoc network is confronted with four different damages: random failure, mobile attack, energy limit and selective attack. These attacks will not only destroy network topology, but also will make the transferring capacity and bandwidth of network to be influenced. An assessment of mobile ad hoc network invulnerability is proposed based on the characteristic of mobile ad hoc network. A definition of invulnerability rate is proposed. The invulnerability rate of network is decided by three factors, i.e., connectivity, transferring capacity, and bandwidth of network. At last, we give two experiments to evaluate the performance of the proposed invulnerability assessment method. The results show that mobile ad hoc network has the very strong invulnerability.
