A distributed delay-constraint routing algorithm for satellite networks

With considering satellite networks' characteristic of few network nodes, limited on-board storage and processing ability etc., a distributed delay-constrained routing algorithm (DDCRA) with mechanism of probe packet is proposed. Based upon strategy of distributed routing and quality of service (QoS), DDCRA reduces the complexity of algorithm so as to lower requirements for the on-board processing equipments. Comparing with the minimum delay routing algorithm, better performances of DDCRA can be achieved.
