Improved medium access control for wireless sensor networks - a study on the S-MAC protocolImproved medium access control for wireless sensor networks - a study on the S-MAC protocol Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2015-11-092005enAn efficient medium access control (MAC) protocol is critical for the performance of a wireless sensor network (WSN), especially in terms of energy consumption. 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 simple and complicated topologies, the enhanced protocol is shown to outperform the original version of S-MAC in energy conservationhttp://creativecommons.org/licenses/by/4.0/5-514th IEEE Workshop on Local and Metropolitan Area Networks Koutsakis Polychronis Κουτσακης Πολυχρονης Paterakis Michalis Πατερακης Μιχαλης Chiras ,T 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
