Steady state analysis of an energy efficient mobility management scheme in IP-based wireless networks

Abstract

An energy efficient mobility management scheme in IP-based wireless networks was proposed to reduce the battery power consumption of mobile hosts (MHs). In order to efficiently manage battery power, radio resources, and network load, the proposed scheme controls six MH states: communicating, attention/cell-connected, attention/paging area-connected, idle, off/attached, and detached states. We derive the stationary probabilities and steady state probabilities of the MH states for the proposed scheme in IP-based wireless networks in compact form. The effects of input parameters on the steady state probabilities and the power consumption of MHs are investigated in the proposed scheme and conventional scheme based on Erlang and Gamma distributions. The analytical results provide guideline for proper selection of system parameters and can be utilized to analyze the performance of mobility management schemes in IP-based wireless networks. © 2010 Springer-Verlag Berlin Heidelberg.
