An energy-efficient and delay-constrained resource allocation scheme for periodical monitoring traffic in SmartBANs
Jaume Ramis, Loren Carrasco-Martorell · 2017
This work presents a SmartBAN MAC configuration that significantly increases sensors battery lifetime through reducing transceivers energy consumption. To that end, the proposed resource allocation scheme determines the inter-beacon intervals duration and sensors transmission periods in order to allow sensors transceivers remain in sleep mode as long as possible while satisfying delay requirements of scheduled and contention traffic. Numerical results demonstrate that battery lifetime can be significantly expanded with the proposed scheme, specially for sensors with long transmission periods.
