Optimal protection resource allocation: A perspective of network science

Wireless network's traffic capacity is one of the most important measurements of network performance. In a vulnerable network environment, attacks for network components can cause degradation of traffic capacity and lead to increasing network congestion and overall performance degradation. In this paper, we propose an effective protection resources allocation scheme which allocates limited protection resources of nodes based on assessment of vulnerability of network components. This scheme proves to be the best allocation strategy in respect to enhancing the quantity of network traffic capacity. The simulation results show that the proposed allocation scheme outperforms other traditional allocation schemes based on critical node analysis. A thorough analysis of traffic capacity and network vulnerability has also been provided.
