Routing Algorithm Based on Non-cooperative Differential Games in Deep Space Networks

Most of the existing routing protocols from those in the terrestrial networks can not be directly applied in Deep Space Information Networks (DSINs), because of its inherent outstanding characteristics, such as bandwidth constraints, high latency, asymmetric data rates, and heterogeneous network architectures. Therefore, designing an optimal routing algorithm that is suitable for DSINs becomes a challenging and interesting problem. In this paper, a bandwidth allocation scheme based on non-cooperative differential game is proposed. Our scheme takes the selfness of nodes into consideration. It is shown that our proposed scheme can effectively allocate bandwidth with bandwidth constraints, and is more feasible and adaptive to DSINs with bandwidth constraints.
