The Impact of CSMA/CD and Token Ring on System Performance and Stability of Integrated Wired and Wireless Networks

Computer networks can be built using either wired or wireless technology. Although wired network has been the traditional choice, wireless technologies are becoming more popular. The primary purpose of this paper is to analyze the impact of a wired access method Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol and Token Ring protocol on the performance of an integrated wired with wireless LAN. Packet Reservation Multiple Access (PRMA) is used for wireless networks. The performance parameters, such as delay and throughput, of an integrated model have been analyzed in both PRMA-CSMA/CD and PRMA-Token Ring. In order to do a numerical analysis for both PRMA-CSMA/CD and PRMA-Token Ring, we built our own simulator using MATLAB 6.5. A numerical analysis based on the performance analysis presented in this paper may help in studying the affect of wired access method CSMA/CD and Token Ring on system performance and stability of integrated wired with wireless networks.
