Abstract :
In the IEEE 802.15.4 MAC protocol, peer-to-peer transmission between a pair of neighboring nodes is not easy due to nodes frequently staying at sleeping mode. However, in star topology, data exchanging between two non-hidden nodes are relayed by a network coordinator which spends double power consumptions for one valid frame transmission from sender to destination. This paper proposes a day and night access (DNA) scheme to enhance transmission efficiency and to minimize power consumption simultaneously. Simulation results demonstrate that DNA scheme outperforms IEEE 802.15.4 MAC standard in terms of data update success rate, data update latency and energy dissipation per update.
