| Abstract | ||
| Abstracts Different wireless networks satisfy different users. The proposition of a single unified handoff approach is to offer the end user the quality of service (QoS) required. In this paper, vertical handoff between wireless fidelity (Wifi) and Universal Mobile Telecommunication System (UMTS) networks is investigated using MATLAB program 7.4 in order to maintain constant throughput during handoff. Three different propagation models are used. The variation of throughput with distance, received signal strength with distance and the effect of different speeds in macro and microcells are dealt with. Keywords: Vertical handoff, Throughput, Speed, Micro and Macro cells. | ||
