Abstract
Always Best Connected (ABC) concept allows the best connectivity to mobile users anywhere at any time in heterogeneous network environment. To answer its requirement, Network selection techniques play a considered role in providing the best QoS in such environment. In this paper authors study the use of Multiple Attribute Decision Making (MADM) used to choose the best network from available networks. Authors compare handover decision algorithms: MEW (Multiplicative Exponent Weighting), SAW (Simple Additive Weighting) and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) in terms of end-to-end delay and packet loss using Two available networks WLAN and Wimax in NS-3. All algorithms allow different attributes (e.g., bandwidth, delay, Jitter and Bite Error rate) to be included in the simulation.
