Design and Performance Analysis of Wireless Campus Network Using Delay Parameter
Keywords:WLAN, QoS, Delay, Wireless Workstations and OPNET IT GURU
Abstract- Wireless Campus Network is a network that covers an educational or corporate campus. It is a network of multiple interconnected local area networks in a limited geographical area. Wireless local area networks use infrared or radio waves to provide network for wireless devices and allow users to transmit data between each other in the coverage area without the limitation of wire and cable. Quality of Service (QoS) is considered as one of the main issue in Wireless Network due to the bottleneck and the competition among different kinds of traffic flow on the network. In this paper a wireless Campus Network design was developed to compare the QoS performance improvement of Wireless Campus Network using delay parameter. Two models (Short-Term and Long-Term) were designed and simulated using Optimized Network Engineering Tool, OPNET IT GURU Academic Edition with linked between wireless workstations suitable for implementation to determine network delay performance. The two models contain the same number of wireless workstations but with some additional access points and multiples processors in the long-term model a point-to-point protocol (PPP) were employed to connect the access points with the routers and the cloud while 100BaseT cable was used to connect the servers and the firewalls. The wireless network delay were obtained in each case. The results obtained from this models showed that the Long-Term Model experiences much lower wireless network delay compared to the short-Term Model. This could be attributed to the fact that even though the total number of wireless workstations are the same in both model but the topology of the long-term model contains additional Access Points and double processors which resulted to the observed minimum delay.
