COMPARISON OF LTE AND WIMAX USING SYSTEM LEVEL SIMULATIONS IN NS2
In telecommunications, 4G is the fourth generation of cell phone mobile communications standards. There are many features associated with 4G, which make it promising. On the other hand, new applications required to be supported by new mobile systems include a variety, VoIP, video conference, multimedia messaging, multi-player games, virtual private networks (VPN), etc. All these applications require higher throughput, wider BW, smaller delay, and innovative transmission methods that will give
... gher spectral efficiency and good quality. Two leading emerging technologies are: LTE (Long Term Evolution standardized by third generation partnership project (3GPP) and WiMAX (the IEEE802.16e, the worldwide interoperability for microwave access) are considered able to fulfil the 4G requirements announced by ITU-R which is known as International Mobile Telecommunications Advanced (IMT-Advanced). In this project we will attempt to perform the system-level simulation of these technologies (and also simulate at the link level wherever necessary) and compare them on certain performance parameters by developing comparable 7-cell scenarios for both LTE and WiMAX. Actually, two types of simulations are possible-one on link-level and the other on system level. Merging both increases computing complexity. Therefore, we go for certain abstractions and instead focus on system level simulation. Future scope of both these technologies is enormous. Also, both the technologies have their own advantages and disadvantages. In future, a network may be possible which combines the advantages of both these technologies.
