An Integrated System for Wireless Cellular and Ad-Hoc Networks Using Fuzzy Logic

Abstract

Several solutions have been proposed for improving the Quality of Service (QoS) in wireless cellular networks, such as Call Admission Control (CAC) and handover strategies. However, none of them considers the usage of different interfaces for different conditions. In this work, we propose the Fuzzy-Based Multi-Interface System (FBMIS), where each node is equipped with two interfaces: the traditional cellular network interface and Mobile Ad hoc Networks (MANET) interface. The proposed FBMIS system is able to switch from cellular to Ad-Hoc mode and vice versa. We consider three input parameters: distance between nodes, node mobility and the angle between node and the base station. We evaluated the performance of the proposed system by computer simulations using MATLAB. The simulation results show that our system has a good performance.
