چکیده

Low earth orbit (LEO) satellite systems gained considerable interest in the past decade and were expected to be instrumental in future telecommunications systems. Nevertheless, the first two LEO satellite networks that are currently in operation have not come to fruition on account of the limited spectrum of services that they provide. In this context, future LEO satellite networks will be geared towards the provision of multimedia services. In this paper a novel call admission control and inter-satellite handover management scheme tailored for multimedia LEO satellite systems is proposed and evaluated. In addition, the proposed scheme is examined in satellite diversity based systems and two different satellite selection criteria, which can be applied to both new and handover requests, are assessed.

QoS handover management for multimedia LEO satellite networks

Low earth orbit (LEO) satellite systems gained considerable interest towards the end of the previous decade by virtue of some of the appealing features that are endowed with, such as low propagation delay and the ability to communicate with handheld terminals. However, after the limited commercial success of the first networks of this kind, future satellite networks are now conceived as complem...

A New Connection Admission Control for Spotbeam Handover in LEO Satellite Networks

Frequent spotbeam handovers in low earth orbit (LEO) satellite networks require a technique to decrease the handover blocking probabilities. A large variety of schemes have been proposed to achieve this goal in terrestrial mobile cellular networks. Most of them focus on the notion of prioritized channel allocation algorithms. However, these schemes cannot provide the connection-level quality of...

A new spotbeam handover management technique for LEO satellite networks

AbstmctThe geographical connection admission control (GCAC) algorithm is introduced for low earth orbit LEO) satellite networks. The GCAC scheme estimates the L u r e handover blocking probability of a new call attempt based on the user location database, in order to decrease the handover blocking. By simulation, it is shown that the proposed GCAC scheme guarantees the handover blocking probabi...

Call Admissibility for Multiservice Traffics in Low-Earth Orbit (LEO) Satellite Networks*

In a LEO system, a user’s call may be handed over constantly from one satellite to another due to visibility changes caused by satellites’ movements. The resultant system performance will degrade if handover calls occur frequently but few are transferred successfully. This paper considered a multiservice LEO system that allows different bandwidth/channel allocations (so-called multirate) on-dem...

Call admission method for call dropping probability guarantee in LEO satellite networks

This paper proposes a new call admission control scheme considering the call dropping probability of ongoing calls in LEO satellite networks. Quality of service (QoS) provisioning of low handover failure probability is used in the proposed call admission control (CAC) scheme to guarantee predefined acceptable call dropping probability for each call. To ensure the call dropping probability the h...
