The Wireless Campus Network is a network covering University or business campus. It is a network in a small geographical region with several interconnected local area networks. To build a network for wireless devices, wireless local area networks use infrared or radio waves to allow users to relay data to each other without wire to cable limitations in the coverage area. Quality of Service (QoS) is considered one of the key challenges in wireless networks because of the bottleneck and the competition between different modes 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), 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 these models showed that the Long-Term Model experiences much lower wireless network delay compared to the short-Term Model. Even though the number of wireless workstations are the same in both model but the topology of the longterm model contains additional Access Points and double processors which resulted to the observed minimum delay.
