Research on Multicast Routing in Deep Space Sensor Network

In recent years, with the progress and development of human society, the needs of extraterrestrial energy exploration and solar living space development has become more and more urgent. Deep Space Sensor Network has a unique conditions and technical advantages in deep space exploration due to its characteristics of low power, low cost, distribution and self-organization. Multicast routing protocol of Deep Space Sensor Network based on the architecture of Delay and Disruption Tolerant Networks is the focus of work. A new multicast routing protocol named MPDSSN is proposed in this paper. At last, after setting simulation environment and parameters, the author use NS2 simulation tool to simulate MPDSSN. Simulation results show that MPDSSN has more superior performance in the average delay, energy saving, survival time and packet loss ratio.
