Low Earth Orbit (LEO) satellite networks are foreseen to complement terrestrial networks in future global mobile networks. Although space segment topology of a LEO network is characterized by periodic variations, connections of mobile stations (MS’s) to the satellite backbone network alter stochastically. As a result the quality of service delivered to users may degrade. Different procedures ha...

Satellite-terrestrial (ST) networks, in which many nodes are interconnected by both satellite and terrestrial networks, can efficiently support multicast services. This is because satellite broadcasting is suitable for a large multicast group and a terrestrial network is suitable for a small multicast group. An ST network requires a multicast routing algorithm that can select the appropriate sa...

This paper presents the handover management in mobile satellite communications with multimedia traffic. Multimedia traffic is becoming the next hop in mobile satellite communication, due to its demand. The coverage of the satellite network knows no boundary and with the concept of the broadband satellite network, communication for multimedia and high-data rate multimedia communications can be p...

Future Low Earth Orbiting spacecrafts will contain several IP-enabled devices that are accessible by users through ground stations. As the spacecraft moves around the Earth, mobility solution, such as Mobile IPv6 can be used to handle the mobility of the devices when satellites handover between ground stations. However, if the devices are connected to an on-board Local Area Network, the mobilit...

The International Maritime Satellite (Inmarsat) communication service can be used to provide a wide area network (WAN) connection for a local area network (LAN) to the home LAN from almost anywhere on the earth. The communication link of the WAN connection is achieved through the satellite network of Inmarsat and a land-earth digital telephone network, such as Integrated Services Digital Networ...

The broadband satellite multimedia (BSM) architecture standardised by ETSI defines a satellite independent service access point (SI-SAP) interface layer that separates the satellite independent features of the upper layers from the satellite dependant features of the lower layers, and provides a mechanism to carry IP-based protocols over these satellite dependent lower layers. This enables inte...

Network computing seeks to utilize the aggregate resources of many networked computers to solve a single problem. In so doing it is often possible to obtain supercomputer performance from an inexpensive local area network. The drawback is that network computing is complicated and error prone when done by hand, especially if the computers have diierent operating systems and data formats and are ...

Device-to-Device (D2D) paradigm is one of the key enablers for boosting energy efficiency (EE) networks. For actualization EE in multi-mode heterogeneous D2D networks, resource allocation should be executed accordingly. In that regard, we study management networks where there a LEO satellite and cellular base station (BS) with user devices (satellite, BS connectivity modes) dispersed terrestria...

Mobility management is required to ensure the session continuity for multiple IP-enabled devices onboard a satellite that hands off between ground stations. Network Mobility (NEMO) can efficiently manage the mobility of multiple IP-enabled devices that are connected as a mobile network. However, existing mobility management solutions for satellite networks are unable to route through intermedia...
