Abstract

Presently, the wireless mobile networks and devices are becoming increasingly popular to provide users the access anytime and anywhere. The mobile systems are based on cellular approach and the area is covered by cells that overlap each other. In mobile cellular systems the handover is a very important process to maintain the desired Quality of Service (QoS). Many handover algorithms are proposed in the literature. However, to make a better handover and keep the QoS in wireless networks is very difficult. During handover decision in cellular networks, there is a risk of making incorrect decision based on incomplete or outdated information. For this reason, we use Fuzzy Logic (FL) which can operate with imprecision data. The context-triggered actions are carried out based on simple IF-THEN rules. In different from other works, we use Random Walk (RW) model and FL to design a new handover system, which is able to avoid ping-pong effect and has a good handover decision. The performance evaluation via simulations shows that proposed system can avoid ping-pong effect and has a good handover decision.
