This contribution is concerned with the performance evaluation of topology control algorithms for indoor ad hoc networks in multi-storey buildings. Several proposed topology control algorithms based on discrete sets are compared. The topology control algorithms operate with wireless links having variable transmission rates according to existing wireless communication standards. The maximum number of routing steps is limited to 15 hops. Computational experiments with a queuing analyzer for open networks are performed to extimate the connectivity between distant nodes in the network located at different vertical levels. The tradeoff between connectivity and delay-throughput is studied assuming that the algorithms are constrained to the selection of only five links by each node.
