The realization of deep space scientific missions are enabled by the developments in the space technologies. TCP can not provide effective communication service in deep space links because of the long propagation delay and high BERs characteristics.Scientific community propose Delay Tolerant Network (DTN) for resolving the communication problem between earth and other planet. DTN introduces a new layer in the protocol stack called Bundle Layer that is placed between application layer and transport layer.DTN calls the transport protocols that it uses to move data across different networks convergence layers. This study present a novel Network Coding based convergence layer Reliable TransPort mechanism(NC-RTP) in order to provide effective communication service between DTN peers. This mechanism transmit a coded bundle every M original bundles(M is related to the packet error rate of the communication link). The coded bundle is a random linear combination of previous M original bundles. Using coded bundle and (M-1)original bundles, the receiver could decode and generate a single lost bundle of previous M original bundles . In this way, NC-RTP could compensate any single lost bundle in (M+1) transmitted bundles(including M original bundles and 1 coded bundle).Our theoretical and simulation performance evaluation results reveal that NC-RTP can enhance transmit reliability and make file transfered faster.

“…Higher link asymmetries are planned for future DMC satellites, which will have faster downlinks for higher-resolution imagery. The file transport protocol used is Saratoga, 3 a simple, high-rate, rate-based, negative-acknowledgement UDP/IP-based file transfer protocol that can operate over extremely asymmetric links and tolerate loss. Saratoga is specified in a public internet-draft.…”

This paper describes network-centric operations, where a virtual mission operations center autonomously receives sensor triggers, and schedules space and ground assets using Internet-based technologies and service-oriented architectures. For proof-of-concept purposes, sensor triggers are received from the United States Geological Survey (USGS) to determine targets for space-based sensors. The Surrey Satellite Technology Limited (SSTL) Disaster Monitoring Constellation satellite, the UK-DMC, is used as the space-based sensor. The UK-DMC's availability is determined via machine-to-machine communications using SSTL's mission planning system. Access to/from the UK-DMC for tasking and sensor data is via SSTL's and Universal Space Network's (USN) ground assets. The availability and scheduling of USN's assets can also be performed autonomously via machine-to-machine communications. All communication, both on the ground and between ground and space, uses open Internet standards.

“…DTN has gained popularity over the years with several research in areas such as the Interplanetary Networks (IPNs) for space and satellite communication [3], Airborne Networks (ANs) [4], Delay-Tolerant Sensor Networks [5], Vehicular Ad hoc Networks [6], Underwater Networks (UWNs) [7] and Pocket-Switched Networks (PSNs) [8]. A number of research works have been carried out and are still on-going in DTN routing [9], congestion control/buffer management [10], convergence layer design [11], application layer design [12], and flow control [13] but very little on DTN security.…”

Denial of Service (DoS) attacks are a major network security threat which affects both wired and wireless networks. The effect of DoS attacks is even more damaging in Delay Tolerant Networks (DTNs) due to their unique features and network characteristics. DTN is vulnerable to resource exhaustion and flooding DoS attacks. Several DoS mitigating schemes for wired and wireless networks have been investigated and most of them have been found to be highly interactive requiring several protocol rounds, resource-consuming, complex, assume persistent connectivity and hence not suitable for DTN. To mitigate the impact of resource exhaustion and flooding attacks in DTN, we propose a security scheme which integrates ingress filtering, rate limiting and light-weight authentication security mechanisms to monitor, detect and filter attack traffic. We propose three variants of lightweight bundle authenticators called DTNCookies. To make the proposed DTNCookies random and hard to forge, we exploit the assumption that DTN nodes are loosely time-synchronized to generate different nonce values in different timeslots for the computation and verification of our proposed DTNCookies. The results demonstrate the efficiency and effectiveness of the proposed scheme to detect and drop attack traffic. The simulation results also show good performance for the proposed scheme in terms of energy and bandwidth efficiency, high delivery ratio and low latency.
