This paper provides a general analytic method to estimate the handover rate in mobile packet systems with heterogeneous cell types and multimedia services. The handover rate is derived as a closed-form function of the Laplace transform of the session time distribution. The proposed model can be easily extended to analyze the mobility feature of the heterogeneous mobile systems with hierarchical cell...
This correspondence describes an efficient Bayesian framework for localization of moving terminals (MTs) in wideband wireless networks. In a previous paper, the authors have presented a grid-based technique, based on a hidden Markov model, that used the power delay profiles of the received signals to track the MT position. This grid-based Bayesian method has proved its efficacy in reducing localization...
