Abstract

Vertical handoff is crucial to future wireless communication. In this paper, a two-step vertical handoff decision algorithm based on dynamic weight compensation is proposed. This algorithm adopts the filtering mechanism to reduce the system cost and improves the conventional algorithm by dynamic weight compensation and consistency adjustment. The experimental results show that our algorithm outperforms the traditional algorithm by increasing the consistency of decision matrix, fully taking advantages of the range of network choices and reaching a better load balance of the whole wireless environment.
