Universidad de Zaragoza (orcid)0000-0002-0299-0859 PSM-DMO: power save mode and discontinuous BLE mesh operation 2022 Access copy available to the general public Unrestricted The Bluetooth Low Energy (BLE) mesh profile, standardized by the Bluetooth Special Interest Group (SIG), has an increasing interest in IoT solutions. However, the standard assumes that relay and friend nodes should be continuously scanning the channel awaiting any incoming transmissions. This could be very inefficient in terms of energy consumption, particularly in application scenarios where the backbone of the mesh network cannot be powered and traffic is infrequent. Hence, we present a novel strategy, named PSM-DMO, that minimizes the scan periods and thus, significantly reduces the overall energy consumption of the mesh network. PSM-DMO is defined as a new and optional feature for the currently published BLE mesh specifications, coexists with the standard operation, and is implemented without modifying the core of the specification. The proposal, that ensures the reliability of the mesh operation, can be used in BLE sensor networks that can tolerate a certain transmission delay. PSM-DMO replaces the continuous scan by a periodic but asynchronous polling process whereby the relay and sink nodes interrogate their neighbors about the existence of data to receive or to retransmit through the network. Nodes only go into scan mode during the period of time the mesh network will be involved in the transmission and dissemination. This period is estimated by the node which is the source of data, it is announced to its neighbors and it is propagated consecutively by all the relay nodes until the destination. PSM-DMO allows a theoretical reduction in the energy consumption of relay nodes up to 99.24 %. info:eu-repo/grantAgreement/ES/DGA/T31-20R info:eu-repo/grantAgreement/ES/MICINN/RTI2018-095684-B-100 info:eu-repo/grantAgreement/ES/MICINN/RTI2018-099063-B-100 info:eu-repo/grantAgreement/ES/MINECO/RTI2018-099880-B-C32 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 5.6 2022 ENGINEERING, ELECTRICAL & ELECTRONIC 56 / 274 = 0.204 2022 Q1 T1 COMPUTER SCIENCE, HARDWARE & ARCHITECTURE 8 / 54 = 0.148 2022 Q1 T1 TELECOMMUNICATIONS 23 / 88 = 0.261 2022 Q2 T1 COMPUTER SCIENCE, INFORMATION SYSTEMS 41 / 158 = 0.259 2022 Q2 T1 1.625 2022 Computer Networks and Communications 2022 Q1 10.7 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Pérez Díaz de Cerio, D.
