Distributed scheduling, contention, interference, TDMA, queuing network modelling


Maximizing battery lifetime and throughput is important in today’s WLAN networks. In this work, we propose a distributed scheduling algorithm above the MAC layer that addresses these problems. We test our ideas on a heterogeneous wireless sensor network we have deployed in southern California – HPWREN. The results show that with our scheduling algorithm it is possible to achieve a throughput improvement of up to 10.31% and maximum power saving of 85.54%.
