“…In an ATM-based satellite (SATATM) network, all satellites in the network use multispot beams with complex onboard processing and switching (OBP/OBS) capabilities [2][3][4]. This can alleviate the network dependency on the ground services such as the gateway stations and the network control centre (NCC), and it can also provide a quick deployment of ATM connectivity using the exiting satellites.…”

“…One of the significant differences between a mobile satellite network and a terrestrial cellular network is that the former one is a periodical and predicable network. This means that because of the satellites' periodical movement along the corresponding earth orbits, the position of the satellites in the space can be accurately predicted and pre-calculated [1][2][3]. This information is very important because in a mobile satellite network, the movement of the satellites can be considered as the main cause of handoffs.…”

“…Asynchronous transfer mode (ATM) has already demonstrated its capability in providing network quality of service (QoS) guarantee along with its reliable high-bandwidth capability [3,4]. In order to take the advantages of the LEO/MEO satellite network and the ATM, it is proposed to integrate these two to form a new network, namely LEO/MEO SATATM network, for the future communication systems [1,2,5]. Within this network, inter satellite links (ISL) may be applied as the space links to provide global accessibility and to enable the LEO/MEO SATATM networks to be used as the backbone for the next generation global wireless networks [1,3,4].…”

“…The low/medium earth orbit (LEO/MEO) satellite networks take more and more important roles in the wireless communications world because of several outstanding features, such as global coverage, low propagation delay and high capacity [1,2]. Asynchronous transfer mode (ATM) has already demonstrated its capability in providing network quality of service (QoS) guarantee along with its reliable high-bandwidth capability [3,4].…”

“…Such an issue motivates the research of combining ATM and mobile IP (MIP) networks to generate a new kind of network, the 'MIP over ATM' network [6][7][8]. The LEO/MEO SATATM network is a very promising solution to global MIP services because of its capability of global evaluating the network efficiency [1][2][3] although it also depends on the requirements from different applicants. One of the significant differences between a mobile satellite network and a terrestrial cellular network is that the former one is a periodical and predicable network.…”

SUMMARYMobile satellites can be considered as the promising solution to the global IP network. In order to provide quality of service (QoS) in future networks, mobile satellite can be integrated with the asynchronous transfer mode (ATM) to switch IP datagrams in the space. For such a network, new and sophisticated routing and handoff algorithms are essential. In this paper, a new scheme called adaptive path routing scheme (APRS) is proposed. It is shown that the APRS can provide superior performance for routing and handoff in mobile satellite networks compared with conventional schemes.

ATM is the promising technology for supporting high-speed data transfer potentially suitable for all varieties of private and public telecommunications networks. IP, on the other hand, is the fast-growing internet layer protocol that is potentially applicable over any data link layer. New IP-based multimedia applications require much higher bandwidth compared to the traditional applications run over the Internet which ignited the usage of the ATM in IP networks. With the revolutionary development in wireless cellular network in recent years and the requirements of broadband data applications over the wireless channel, ATM and IP networks find their way of contribution in this underlying network. Mobility in wireless environment could however take its ultimate freedom when an integrated cellular-satellite supports the physical layer of the network. In order to provide a global mobility for the future multimedia personal terminals, thus, there is a requirement of integration of all these telecommunications technologies. Wireless ATM came to integrate the cell-switched ATM facilities in wireless environment and mobile IP has a similar goal for IP networks. IP over ATM also proposed to merge the two leading technologies of IP and ATM into a fast and efficient way of multimedia data transmission. Broadband ATM satellite systems also have been proposed in order to make the satellite channel a high-speed link for future networks. In this chapter, we will explain all these technologies and their mutual integration and then look into the issues of mobile satellites, ATM, and IP in a novel way in order to introduce the integration of the three technologies for future high-speed, global mobility-supporting, Internetcompatible wireless communication networks. We will discuss the applications and their traffic and quality of service requirements. These are crucial issues that need careful considerations for future multimedia applications over the Internet.
