Investigation of Macrocell Microcell Channels Selection In Multitier Cellular Networks

الملخص EN

A proposed method of Microcell / Microcell channel selection in multitier cellular system using sojourn time of microcell overlapped region.

To keep the handoff rate to acceptable level, low mobility users (with speed V < Vth) should undergo handoffs at microcell boundaries and high mobility users (with speed V > Vth) should undergo handoffs at macro cell boundaries.

Investigation of variation of the number of channels in the microcells and the macro cell with the blocking probability.

Also the variation of microcell radius on the blocking probability for different mobile stations speed.
