Abstract

The vision of Next-Generation networks is to be heterogeneous in nature with an increasing demand in wireless networks. Many wireless networks are deployed with widely varying characteristics. As various networks have widely different characteristics, it is difficult to maintain the quality of service after executing a handoff from one network to another network. Maintaining the quality of service, based on applications, during the handoff in heterogeneous networks needs an intelligent handoff decision mechanism. In order to utilize the full heterogeneous networks, the mobile terminal may handoff from one network to another by many reasons. Development of efficient handoff algorithm for cost-effective, and that can enhance the capacity as well as quality of service of cellular system. A fuzzy based handoff algorithm is proposed in this paper as a solution to this problem. Handoff on the basis of ratio of slopes of normal signal loss to the actual signal loss is presented. The fuzzy based solution is supported by analytical solution. Simulation results show that compared to other vertical handoff algorithms, the proposed algorithm gives better performance for different traffic classes.
