Energy Optimization Mechanism for Mobile Terminals using Vertical Handoff between WLAN and CDMA2000 Networks

Abstract

This paper presents energy optimization mechanism for mobile terminals (MTs) using vertical handoff between Wireless LAN (WLAN) and CDMA2000 networks. Several techniques for optimizing the power consumption of MTs have been considered in literature. Some of these techniques could be used separately or in tandem. Considering the importance of efficient energy management for MTs, the research in this area could be taken a step further. The technique considered in this paper allows a multimode terminal to take advantage of two integrated networks to efficiently manage its energy consumption. Two integrated networks considered are WLAN and CDMA2000. This paper develops an algorithm that allows the MT to always get connected to the most cost-effective network. The results obtained showed that the MTs power is more efficiently managed when the MT is using the integrated networks than when it is using each of the networks independently.
