Velocity adaptive handoff algorithms for microcellular systems

Abstract

Fast handoff algorithms for urban microcells using velocity adaptation and corner detection are presented. Three velocity estimators are compared with respect to their accuracy, sensitivity to non-isotropic scattering, capability of detecting when a mobile turns a corner, and response time in typical microcell environments. Simulation results show that velocity adaptive corner detecting handoff algorithms yield faster and more consistent handoff performance than traditional methods.
