Performance Analysis of Energy Consumption of Mobile Station in Three-Tier Network
Multi-tier network consists of multiple access networks, which are complimentary to each other, from the aspect of mobility support, service coverage area, transmission bandwidth, energy consumption, etc. In previous works on multi-tier network, most of them deal with two access networks. Also the performance of multi-tier location management was analyzed, from the aspect of signaling load or energy consumption. In this paper, the authors extend previous works on energy consumption of two-tier network by considering three access network. Analytical model for mobility and traffic characteristics of MSs in three-tier network is developed and the performance of location management in three-tier network is analyzed in detail by showing the effect of various parameters on the energy consumption of MSs.
