چکیده
A low Earth orbit (LEO) satellite constellation could be used to provide network coverage for the entire globe. This study considers multi-beam frequency reuse in LEO systems. In such a system, channel is time-varying due fast movement of satellite. proposes an efficient power and bandwidth allocation method that employs two linear machine learning algorithms take conditions traffic demand (TD) as input. With aid simple proposed scheme allows optimum resources under dynamic TD conditions. Additionally, projection schemes are added so provided capacity best approximated when exceeds maximum allowable system capacity. The simulation results show outperforms existing methods.

Jointly power and bandwidth allocation for a heterogeneous satellite network
Due to lack of resources such as transmission power and bandwidth in satellite systems, resource allocation problem is a very important challenge. Nowadays, new heterogeneous network includes one or more satellites besides terrestrial infrastructure, so that it is considered that each satellite has multi-beam to increase capacity. This type of structure is suitable for a new generation of commu...
متن کاملDynamic Bandwidth Assignment Multiple Access for Efficient ATM-based Service Integration over LEO Satellite Systems
This paper proposes a novel dynamic bandwidth assignment multiple access (DBAMA) protocol employing a dynamic packet reservation technique for direct user terminal access to a ATM-based low earth orbit (LEO) satellite communications system. Performance analyses by simulations are presented. Methods to efficiently integrate ATM-based BISDN traffic are considered.
متن کاملDYNAMIC RESOURCE ALLOCATION FOR LEO SATELLITE SYSTEMS WITH QoS PROVISION FOR AN IPv6 NETWORK
The approach presented in this paper aims to obtain a QoS for IPv6 protocol over LEO satellites. Most of the switching and access operations in the proposed system will require the intelligent functions to be located on earth. We can allocate links at different bit-rates and no particular assumptions have been made as concerns the access protocol in order to maintain the presented work at a gen...
متن کاملModeling Dynamic Satellite Bandwidth Allocation for Situation-Awareness Applications
Dynamic allocation is a crucial issue when coping with satellite-provided services where many demanding users share a limited bandwidth. This is the case of situation-awareness applications, for example, where several users generate information (possibly multimedia) that must be delivered to a control center through a shared satellite link. In this context, bandwidth allocation should be adapti...
متن کاملPipelined Dynamic Bandwidth Allocation for Power Saving in XG-PON
This paper proposes a pipelined dynamic bandwidth allocation (DBA) scheme for 10-gigabit-capable passive optical networks (XG-PONs). The proposed scheme performs a DBA operation in multiple stages to save power. Also, requests are forwarded to next stages to obtain high performance.
