Demo Abstract: Cross Layer Design for Low Power, Low Delay, High Reliability Radio Duty-Cycled Multi-hop WSNs
We present a cross-layer approach for delivering low delay, low power and highly reliable sensor data transfer in radio duty-cycled multi-hop wireless sensor networks. We develop a novel routing metric that uses a number of weighted physical and logical parameters to enable better parent selection for routing data towards the sink. Trading latency against reliability, we demonstrate competitiveness with the state of the art, namely ORW and CTP, through direct comparison using real traces obtained from a 52 node deployment. We demonstrate reliability in excess of 99.9 % in all cases, improved energy efficiency over the state of the art, with minimal trade-offs in terms of end to end latency.
