Handover Failure Reduction in LTE

Abstract

Handover is a very important process in any mobile communication network because it allows the service to be continues and to supply Quality of Service (QoS) to the users. However the handover increases the signaling load and also handover failure affects network performance because Service interruptions can be devastating. The algorithm depend on knowing the current location of the user, and Compare it with the Previous location to determine the angle of direction of the movement. Based on this information the handover decision can be made. This algorithm is tested under two parameter the speed of the mobile and average inter arrival. The simulation results shows that the proposed algorithm has no Handover failure under the speed 60Km/h and no handover failure if average inter arrival under 3min. This algorithm improve the network performance by reducing the number of handover failure. It is really one of the aspirations that this study will encourage further researches and studies in this field.
