Abstract:
|
Machine-to-Machine (M2M) networks must be
energy-ef¿cient to operate autonomously for years, or even
decades. In this paper, we consider a synchronized duty-cycled
M2M network composed of a huge number of dormant devices
that periodically wake up to transmit data to a coordinator.
We propose the use of Distributed Queuing (DQ) tree-splitting
algorithms to optimize the shared access to the channel among
the high number of devices, in order to improve the energy
ef¿ciency and thus extend the network lifetime. We evaluate
the energy performance of DQ access in this kind of dense
M2M networks, and we compare it to traditional access schemes
based on variations of Frame Slotted-ALOHA (FSA) and the
Contention Tree Algorithm (CTA). Computer-based simulations
show that DQ can reduce the energy consumption in more than
a 50% with respect to FSA and CTA. Results show that there
is an optimum number of contention slots which maximizes the
energy ef¿ciency of DQ regardless of the number of devices. The
performance evaluation presented in this paper also compares
the energy consumption of DQ using low power Wi-Fi and IEEE
