Interaction of Retransmission, Blacklisting, and Routing Metrics for Reliability in Sensor Network Routing [link]Paper  abstract   bibtex   
Unpredictable and heterogeneous links in a wireless sensor network require techniques to avoid low delivery rate and high delivery cost. Three commonly used techniques to help discover high quality paths include (1) link-layer retransmission, (2) blacklisting bad links, and (3) end-to-end routing metrics. Using simulation and testbed experiments, we present the first systematic exploration of the tradeoffs of combinations of these approaches, quantifying the effects of each of these three techniques. We identify several key results: One is that per-hop retransmissions (ARQ) is a necessary addition to any other mechanism if reliable data delivery is a goal. Additional interactions between the services are more subtle. First, in a multihop network, either blacklisting or reliability metrics like ETX can provide consistent high-reliability paths when added to ARQ. Second, at higher deployment densities, blacklisting has a lower routing overhead than ETX. But at lower densities, blacklisting becomes less stable as the network partitions. These results are consistent across both simulation and testbed experiments. We conclude that ETX with retransmissions is the best choice in general, but that blacklisting may be worth considering at higher densities, either with or without ETX.

 Unpredictable and heterogeneous links in a wireless sensor network
 require techniques to avoid low delivery rate and high delivery
 cost. Three commonly used techniques to help discover high quality
 paths include (1) link-layer retransmission, (2) blacklisting bad

 testbed experiments, we present the first systematic exploration of
 the tradeoffs of combinations of these approaches, quantifying the
 effects of each of these three techniques. We identify several key
 results: One is that per-hop retransmissions (ARQ) is a necessary
 addition to any other mechanism if reliable data delivery is a
 goal. Additional interactions between the services are more
 subtle. First, in a multihop network, either blacklisting or
 reliability metrics like ETX can provide consistent high-reliability
 paths when added to ARQ. Second, at higher deployment densities,
 blacklisting has a lower routing overhead than ETX. But at lower
 densities, blacklisting becomes less stable as the network
