Network Congestion Control in 4G Technology Through Iterative Server Khaleel Ahmad 1 CSE & IT Deptt, Swami Vivekanand Subharti University, Meerut, UP, India Sunil Kumar 2 CSE & IT Deptt, Swami Vivekanand Subharti University, Meerut, UP, India Jayant Shekhar 3 CSE & IT Deptt, Swami Vivekanand Subharti University, Meerut, UP, India Abstract During the last few decades, mobile communication has developed rapidly. The increasing dependency of people on telecommunication resources is pushing even more current technological developments in the mobile world. In Real-time multimedia applications, such as Live TV or live movie, video conferencing, VoIP, on-line gaming etc. are exciting applications to the success of 4G.In today’s Internet these applications are not subject to congestion control, therefore the growth of popularity of these applications may endanger the stability of the Internet. In this paper, we propose a novel model to solve the network congestion problem through iterative server. In this model, when a client send a request to server then server will generate a individual iterative server for requesting client. After completing the request, the iterative server will be automatically destroyed. Keywords: Iterative Server, Congestion Control, WiMAX, LTE. 1. Introduction 1.1 First Generation (IG) Mobile networks were deployed in late 1970’s and early 1980's, being a wholly analogue network, providing voice calls. Some of the most successful 1G system is Nordic Mobile Telephone (NMT) System and Advance Mobile Phone System (AMPS)[1]. I) Nordic Mobile Telephone (NMT) System: This system was developed in Europe in 1981. The two variants of NMT are: NMT-450 and NMT-900. The numbers indicate the frequency bands uses. NMT-900 was introduced in 1986 because it carries more channels than the previous NMT-450 network. II) Advance Mobile Phone System (AMPS): This system was developed by U.S. Federal Communications commission in 1983 and allocated 666 duplex channels with 40 MHZ of spectrum in the 800 MHZ band and each channel have a one way bandwidth of 30 KHZ for each duplex channel for the U.S. AMPS. 1.2 Second Generation (2G) Mobile networks was superseded in the 1990s, (GSM, initially Group Special Mobile later changing name to Global System for Mobile Communications) which being digital along with voice it introduced everyone to text messaging (SMS, Short Message Service). 2G technologies can be divided into TDMA-based and CDMA based standards depending on the type of multiplexing used [2] [3]. The main 2G standards are: I) GSM (TDMA-based), originally from Europe but used in almost all countries on all six inhabited continents. Today, it accounts for over 80% of all subscribers around the world. Over 60 GSM operators are also using CDMA2000 in the 450 MHz frequency band (CDMA450). II) IS-95 aka cdmaOne (CDMA-based, commonly referred as simply CDMA in the US), used in the Americas and parts of Asia. Today, it accounts for about 17% of all subscribers globally. Over a dozen CDMA operators have migrated to GSM. III) PDC (TDMA-based), used exclusively in Japan. IV) iDEN (TDMA-based), proprietary network used by Nextel in the US and Telus Mobility in Canada. V) IS-136 aka D-AMPS (TDMA-based, commonly referred as simply 'TDMA' in the US), was once prevalent in the Americas but most have migrated to GSM. 1.3 Second and a half Generation (2.5G) 2.5G is used to describe 2G-systems that have implemented a packet-switched domain in addition to the circuit-switched domain. It does not necessarily provide faster services because bundling of timeslots is used for circuit-switched data services (HSCSD) as well. The first major step in the evolution of GSM networks to 3G occurred with the introduction of General Packet Radio Service (GPRS). CDMA2000 networks similarly evolved through the introduction of 1x1RTT.
