In this work we discuss the efficiency of S-MAC, a well-known MAC protocol for WSNs, and propose an improvement on the protocol. Via an extensive simulation study considering the cases of both a simple linear topology and a complicated tree topology used for structural health monitoring, the performance evaluation of the enhanced protocol shows that it outperforms the original version of S-MAC in energy conservation.http://creativecommons.org/licenses/by/4.0/1st IEEE International Symposium on Wireless Pervasive Computing Koutsakis Polychronis Κουτσακης Πολυχρονης Papadakis, Hélène Institute of Electrical and Electronics Engineers Communication systems, Wireless Wireless data communication systems Wireless information networks Wireless telecommunication systems wireless communication systems communication systems wireless wireless data communication systems wireless information networks wireless telecommunication systems
