IETF proposed network mobility (NEMO) basic support protocol (BSP) to support network mobility. NEMO BSP is an extension of Mobile IP v6 (MIPv6), and inherits all the drawbacks of MIPv6 (like inefficient routing, high handover latency and packet loss rate). Satellites equipped with several IP-enabled devices are an example of network mobility in space(More)
Saratoga is a lightweight transport protocol based on the User Datagram Protocol (UDP/IP). Saratoga was developed by Surrey Satellite Technology Ltd (SSTL) for file transfers of imaging data recorded onboard the InternetProtocol-based Disaster Monitoring Constellation (DMC) satellites, and has been in operational use from low Earth orbit since 2004.(More)
Delay/Disruption Tolerant Networking (DTN) “bundles” have been proposed for deep-space communication in the “Interplanetary Internet.” This paper describes the first DTN bundle protocol testing from space, using the United Kingdom Disaster Monitoring Constellation (UK-DMC) satellite in Low Earth Orbit (LEO). The mismatch problems between the different(More)
Though Low Earth Orbit (LEO) satellites have some distinct characteristics such as low propagation delay, low power requirements and more efficient spectrum allocation due to frequency reuse between satellite and spotbeams but the higher relative speed than terrestrial mobile networks decreases the quality of service as a result of a huge number of(More)
In low earth orbit(LEO) satellite network Mobility management is one of the key technologies. The aim of mobility management is to track where the subscribers are, allowing calls, SMS and other mobile phone services to be delivered to them. In this paper, we have proposed an idea of controlling the frequency hops and hence controlled the mobility management(More)
Low Earth Orbit (LEO) satellite networks will work as an important role in future global communications as it can provide wireless connectivity to any part of the world. It has some distinct characteristics such as low propagation delay, low power requirements and more efficient spectrum allocation due to frequency reuse between satellite and spotbeams. But(More)
LEO satellite networks are going to play an indispensable role in the development of ubiquitous broadband multimedia systems because of their some attracting characteristics such as low power dissipation, low propagation delay and more efficient spectrum allocation due to frequency reuse between satellites and spotbeams. So they are considered to be the(More)
Third generation (3G) communication networks based on low Earth orbit (LEO) satellites provide a new trend in future mobile communications. LEO satellites provide lower end-to-end delays and efficient frequency spectrum utilization, making it suitable for personal communication services (PCS). However, ongoing communications using LEO satellite systems(More)
A Delay-Tolerant Network (DTN) is a necessity for communication nodes that may need to wait for long periods to form networks. The IETF Delay Tolerant Network Research Group is developing protocols to enable such networks for a broad variety of Earth and interplanetary applications. The Arctic would benefit from a predictive velocity-enabled version of DTN(More)
