异构网中一种能效最优的垂直切换算法
A Vertical Handoff Algorithm with Optimal Energy Efficiency for Heterogeneous Networks
摘要
Abstract
In view of the problem that traditional vertical handoff fails to take a crucial factor,energy effi-ciency,into consideration, an optimal energy efficiency vertical handoff algorithm is proposed. The algo-rithm's core is that the mobile terminal tests and calculates the intensity of different received signals from different candidate networks,and system capacity of different candidate areas. Capacity provided by the en-ergy of each unit in candidate areas is taken as decision criterion to realize handoff to the optimal network. Meanwhile,traditional network factors are combined to perform energy efficiency expansion on the multiple attributes decision algorithm. Simulation results show that the handoff algorithm based on unit energy ca-pacity saves about 10% energy when compared with the traditional one,while the expanded multiple attrib-utes decision algorithm saves about 7% energy. Meanwhile,“ping pang effect” is reduced,thereby impro-ving users'communication experience quality.关键词
