Abstract

Today, two major wireless technologies exist, LTE and WLAN. Greatest challenge is to decide which one to use when both are available. Process of moving a device from LTE to WLAN network is called vertical handover. Many factors could impact the handover decision, and a lot of algorithms exist with their advantages and disadvantages. Here, a new algorithm is proposed which is based on fuzzy logic and a new combination of input factors. Also, a large number of vertical handover could produce ping-pong effect and reduce user performance. According to this, a new solution for reducing ping-pong effect is proposed. A solution is based on graph theory and finding bridges in a graph.
