Distribution of Delivery Distribution of Delivery ProbabilitiesProbabilities
Links with intermediate loss rates Links with intermediate loss rates are common, with no sharp are common, with no sharp transition between high and low transition between high and low packet loss rates.packet loss rates.
Spatial Distribution of Loss RateSpatial Distribution of Loss Rate
Inter-node distance is not strongly Inter-node distance is not strongly correlated with whether nodes can correlated with whether nodes can communicates.communicates.
Time Variation of Loss RateTime Variation of Loss Rate
Most links have non-bursty loss Most links have non-bursty loss patterns.patterns.
Effect of Signal-to-Noise RatioEffect of Signal-to-Noise Ratio
Links with very high signal Links with very high signal strengths are likely to have low strengths are likely to have low loss rates, but in general signal loss rates, but in general signal strength has little predictive value.strength has little predictive value.
