An approach to performance evaluation of cellular mobile networks is proposed, which includes the behavior of handover algorithms in the computation of outage probability. In a general system scenario, with a central cluster and a first tier of interferers, the average outage probability is computed along a trip of the mobile terminal that involves crossing the boundary between adjacent cells. The effects of correlated co-channel interferers are accounted for in the computation of outage probability, as well as in the dynamics of a relative signal strength handover algorithm. Numerical results are presented in terms of average outage probability versus the average number of handovers at various cluster size and cross-correlation parameters.
