Abstract A wireless network is vulnerable to jamming attacks since the network relies on open and shared wireless channels. Maintaining an acceptable level of network performance degradation has been an important problem in the wireless network. This paper studies a scheme for network performance optimization by exploiting dynamic rate control and multi-path routing in the wireless network under probabilistic jamming. We model the optimization problem through maximizing the network utility associated with the effective data flows and propose an effective optimal flow control (EOFC) approach to allocate resource on multiple paths considering the effect of jamming. A novel distributed algorithm is designed to adjust flow rates adaptively on each path using multi-path routing. Our simulation results demonstrate that higher effective network throughput and better fairness can be achieved under jamming by our EOFC algorithm than the standard OFC.
