Exploiting causes and effects of wireless link correlation for better performance

摘要: Contradicting the widely believed assumption of link independence, recently phenomenon reception correlation among nearby receivers has been revealed and exploited for varieties protocols [3], [8], [17], [21], [23], [24]. However, despite diversified correlation-aware designs proposed up to date, they commonly suffer from a shortcoming where is inaccurately measured, which leads them sub-optimal performance. In this work we propose general framework accurate capturing correlation, enabling better utilization lying on top it. Our uses SINR (Signal Interference plus Noise Ratio) detect correlations, followed by modeling correlations in-network use. We show that our design light-weight, both computation storage-wise. apply model opportunistic routing network coding physical 802.15.4 test-bed energy savings 25% 15%.
