Performance of signal strength handover algorithms with interference and correlated shadowings

Abstract

This paper proposes results of an improved analysis of handover initiation algorithms in cellular mobile radio networks. Performance of relative signal strength handover algorithms is derived in a general environment with cross-correlated shadowings and interferers. Numerical results are presented for a bidimensional layout of hexagonal cells as well as for a lineal array of cells. It is seen that both cluster size and cross-correlation parameters may have a noticeable impact on algorithm performance. Hence they should be carefully considered in algorithm design.
