Abstract:
|
The energy-efficiency of Machine-to-Machine
(M2M) communications can be improved by applying
cooperation at the medium access control (MAC) layer. This
means that machines can help each other to establish an
energy-efficient communication thus extending the lifespan of
networks. However, this cooperation requires some kind of
coordination. The Persistent Relay Carrier Sensing Multiple
Access (PRCSMA) protocol has been presented in the literature
as an 802.11-based MAC protocol to coordinate the operation
of these cooperative machines in the context of a Cooperative
ARQ scheme. In this paper, we present the evaluation of
the energy consumption of PRCSMA in the context of M2M
capillary networks. Results are compared to non-cooperative
ARQ schemes and to C-ARQ with perfect scheduling among
the relays, indicating the operational regions where C-ARQ can
help improve the energy-efficiency of M2M communications in
the capillary segment. |
