Performance Issues on the Interoperability between IEEE 802.3 & IEEE 802.11 in Heterogeneous Network Environment
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 5
Abstract
Abstract: This paper addresses network computing that seeks to utilize the aggregate resources of many networked computers that can be installed in heterogeneous environment to solve problems of resource allocation, and so on. In doing this, it has to combine the performance from an inexpensive wired local area network (LAN) and wireless local area networks (WLAN) using different operating system, protocols and topologies due to the drawbacks of wired LAN not supporting mobility, quality of services (QoS) in security, andthe usage of too many cables. The exchange of data from Wired LAN to Wireless LAN and vice versa is also another main issue to be addressed. The interoperability between the IEEE 802.3 and IEEE 802.11 is done atthe data link layer (layer 2) of the OSI model. Network devices like the Switch, Wireless Access Point (WAP), Network Interface Card (NIC) are responsible for this action. Cisco® packet tracer simulation software was used in simulating the IEEE 802.3 and IEEE 802.11 performances in a heterogeneous network environment. The simulation result shows the time-to-live in a local area network to be 128ms while that of the internetwork to be 125ms or less. This makes the LAN data transfer faster than the WLAN, and the information exchange interoperable. This type of network environment is recommended for university campuses and government sectors / ICT agencies.
