Transmission layer design of proximity space links for lunar communication

Proximity-1 protocol developed by CCSDS is considered for a bi-directional proximate space links for the efficient support of deep space mission. The protocol can be considered for proximate space links for the space internet mission which expects to be included in Korean lunar project. However, considering the scenario of the space internet mission and the requirement of its communication payload, the proximity-1 protocol needs to be updated under the scenario of the space internet mission with high data rate and simplified under the requirement of its communication payload in terms of size, weight and power. In this paper, we will address design concept of the transmission layer of the proximate space links for Korean lunar project. Then we will propose candidate transmission layer features of the proximate space based on proximity-1 and other CCSDS standards.
