We first consider time scheduling on a single frequency channel
with the aim of minimizing the number of time slots required (schedule length) to complete a convergecast. Next, we combine
scheduling with transmission power control to mitigate the effects of interference, and show that while power control helps in reducing
the schedule length under a single frequency, scheduling transmissions using multiple frequencies is more efficient. We give lower
bounds on the schedule length when interference is completely eliminated, and propose algorithms that achieve these bounds. We
also evaluate the performance of various channel assignment methods and find empirically that for moderate size networks of about
100 nodes, the use of multifrequency scheduling can suffice to eliminate most of the interference. Then, the data collection rate no
longer remains limited by interference but by the topology of the routing tree. To this end, we construct degree-constrained spanning
trees and capacitated minimal spanning trees, and show significant improvement in scheduling performance over different deployment
densities. Lastly, we evaluate the impact of different interference and channel models on the schedule length.
