NETWORK MODEL ANALYSIS IN OPNET SIMULATION

Abstract

Electronic transfer of data and or information in a particular area requires techniques of telecommunication which is the process of communication between two or among multiple communication systems. The routing of data or information of concern would be dependent of the acceptable communication link of either wired or wireless means, and this must be connected to the already configured server. As there is a need to know which of either local area network (LAN) or wireless local area network (WLAN) would attract demand of the consumer in terms of the flexibility, speed and rate of traffic received; the work in this paper therefore looked keenly to the modeling analysis of both local area network (LAN) and wireless local area network (WLAN) using simulation approach to verify and establish the state of art in the available gap. Parameters of consideration include: Ethernet delay in (sec), Traffic sent (packets/sec) and Traffic received (packets/sec). File transfer protocol (FTP) was used as a traffic application and it was configured for a comprehensive study using Optimized Network Engineering Tools (OPNET) simulator. These parameters were compared in both scenarios, and it was observed that the local area network remained the fastest means of communication over the wireless local area network, as there was no delay in the formal compare to some seconds delay in the later, as the same traffic application was sent in both scenarios. Furthermore, more traffics were considerably received in the case of the LAN over simulated time. According to the simulated results, it has therefore been established that if mobility is not of priority, the local area network is the best. Although, the generated results are OPNET based and there could be little or no different when other network simulators are considered
