Control of Multi-Hop Wireless Networks with Security Constraints

摘要

We consider a control problem in wireless multi-hop networks in which source-destination pairs desire to secure communication. Specifically, a control algorithm is proposed based on the stochastic network optimization to maximize a global utility function, subject to end-to-end secrecy transmission and network stability. To achieve secure communication, we firstly exploit an independent randomization encoding strategy to guarantee the multi-hops secrecy transmission. Then, the control algorithm is decomposed into flow control, routing and resource allocation. Based on the control algorithm, each node makes decisions on the arrival confidential data as well as the users and links. The numerical analysis illustrates that the proposed algorithm can achieve a utility result, arbitrarily close to optimal value.
