Abstract-Low Earth Orbit (LEO) satellites will work as an important component in future data communication networks. LEO satellites provide low end-to-end delays and efficient frequency spectrum utilization, making it suitable for personal communication. However, due to high satellite speed, the ongoing communication using LEO constellations experiences frequent handover. In this paper, we provide an up-to-date comprehensive literature survey on proposed handover schemes for LEO satellite systems. We also present a detailed classification of handover schemes based on a common framework. We first classify the schemes into link layer and network layer handover schemes. Link layer handover schemes are further classified into three categories: (a) spotbeam handover schemes, (b) satellite handover schemes, and (c) ISL handover schemes. Spotbeam handover schemes are categorized based on channel capacity, handover guarantee, and handover prioritization techniques. Network layer handover schemes are also classified depending on connection transfer strategies. Finally, we compare the handover schemes using different Quality of Service.

“…A number of proposed constellation designs (including Skybridge and Spaceway) planned to use an ATM-based MAC frame design. ATMbased routing has been suggested for the constellation network [Werner et al, 1997a], although ATM routing has similar fixed-network assumptions to most IP-based routing.…”

Abstract:Satellite constellations are introduced. The effects of their orbital geometry on network topology and the resulting effects of path delay and handover on network traffic are described. The design of the resulting satellite network as an autonomous system is then discussed.Key words: satellite constellation, network, autonomous system (AS), intersatellite link (ISL), path delay and latency, orbit geometry, Walker, Ballard, star, rosette, Iridium, Teledesic, Globalstar, ICO, Spaceway, NGSO non-geostationary orbit, LEO low earth orbit, MEO medium earth orbit. INTRODUCTIONA single satellite can only cover a part of the world with its communication services; a satellite in geostationary orbit above the Equator cannot see more than 30% of the Earth's surface [Clarke, 1945]. For more complete coverage you need a number of satellites -a satellite constellation. We can describe a satellite constellation as a number of similar satellites, of a similar type and function, designed to be in similar, complementary, orbits for a shared purpose, under shared control. Satellite constellations have been proposed and implemented for use in communications, including networking. Constellations have also been used for geodesy and navigation (the Global Positioning System [Kruesi, 1996] and Glonass [Börjesson, et al., 1999]), for remote sensing, and for other scientific applications.The 1990s were perhaps the public heyday of satellite constellations. In that decade several commercial satellite constellation networks were 14 INTERNETWORKING AND COMPUTING OVER SATELLITE NETWORKSconstructed and came into operation, while a large number of other schemes were proposed commercially to use available frequency bands, then loudly hyped and later quietly scaled back or dropped.1998 saw the long-awaited launch of commercial services using the 66-active-satellite LEO (low-earth-orbiting) Iridium system constructed by Motorola [Leopold and Miller, 1993]. Iridium demonstrated the feasibility of Ka-band radio intersatellite links (ISLs) directly interconnecting satellites for wide-scale intersatellite networking. However, Iridium's commercial feasibility was not demonstrated before its operating company had filed for bankruptcy protection. The widespread adoption of mobile telephony and roaming between cellular networks worldwide, largely due to the European GSM standard, had usurped much of Iridium's expected target 'business traveller' market for voice telephony to satellite handsets during the Iridium system's decade-long design and construction period. Iridium's services were later relaunched by a second company, which did not suffer from the original company's need to repay crippling construction debtsThe 48-active-satellite LEO Globalstar system [Wiedeman and Viterbi, 1993], relying heavily on CDMA-based frequency-sharing technology from Qualcomm, followed Iridium, and found the market for a voice telephony service just as difficult. Its operating company filed for bankruptcy protection in early 2002. As the mass market for satellit...

Store and Forward for Real-Enough-Time Services in Satellite Constellations

The current trend favoring real-time services delivery anywhere at anytime has difficulties to cope with the dynamics of mobile networks. Furthermore, the present Internet network architecture is defeated by environments where links are error prone, intermittent, with high delay and when nodes may disappear unexpectedly. Transport services based on store and forward (such as the Delay/Disruption Tolerant Network architecture) accommodate these challenged environments. Within this framework, satellite constellations play an important role.This contribution first presents the rationale behind store and forward transport services. Satellites and their role are then discussed with the identification of research directions to be investigated from a networking standpoint. Nongeostationary satellite constellations show promising insights for flexible yet robust store and forward transport.
