Performance Improvement of GSM System through the Analysis of Key Performance Indicator for QoS

Abstract

In this report I made a review of the new but rapidly growing area of Quality of Services (QoS) in Mobile Ad-Hoc Networks (MANets). Although the application area of MANets was initially proposed for environments of battled communications and disaster recovery the evolution of the Multimedia Technology and the commercial interest of companies to reach widely civilian applications has made QoS in such networks an avoidable task. In the last recent years we have also seen the reports of bringing QoS in wire-based networks becoming a reality. Many ideas inherited from the wirebased networks can be ported to MANets if they take in to consideration the Bandwidth Constraints, the Dynamic Topology and the Constrained Processing and Storing Capabilities of MANets. In this report we will have a glance at successful QoS Models and Protocols of the IP network such as IntServ, DiServ and RSVP and see how they have acted the evolution of Models and Protocols in the Wireless Ad-Hoc world. The report is mainly concentrated on QoS Models, Signaling Protocols and QoS Routing that have been proposed for MANets. Although QoS MAC Protocols are equivalently important to achieve a complete QoS Architecture they are out of the scope of this report.
