Finding optimized transmission power for clustering of S-MAC protocol in WSNs
Anusorn Chungtragarn, Phongsak Keeratiwintakorn · 2007
By using a sleep schedule technique, S-MAC can reduce the energy consumption in a wireless sensor network; thus, breaking the network into a virtual cluster. Using a different sleep schedule in each cluster causes problems in the S-MAC protocol. This paper aims to investigate the appropriate cluster size for the wireless sensors networks (WSNs) in terms of the average node number per virtual cluster. This is to show the effect of cluster size on the network performance parameter such as latency and energy consumption. The experiment results are obtained using the NS-2 simulator.
