Paper Abstract

Support of voice and data applications over networks comprising of an integrated wireless and wire users is of an increasing importance in future technologies of unified networks. Unified networks are integrated wireless and wire networks with Wire, Wireless, Mobile, Multimedia and Satellite applications. Most data applications on wire networks use TCP/IP as an end-to-end flow and congestion avoidance protocol. Standard TCP reacts to packet loss due to RF link fading as congestion and consequently suffers from throughput degradations in pure wireless networks. The main contribution of this paper is how to obtain the maximum achievable throughput for integrated wireless and wire networks. Numerical result shows that if the packet loss due to fading is filtered out, the maximum achievable throughput for wireless/wire network is within 10% of the throughput of a pure wire network. There is a need for modified TCP protocol or a new TCP protocol that can provide reliable data transfer and maximum allowable throughput for an integrated wireless and wire networks. New or modified TCP protocols for wireless/wire integrated networks should aim at achieving for exceeding this throughput.
