Abstract
As Bit errors fluctuate wildly in different environments and they fluctuate steadily for a given
pair of sensor nodes, we propose an error-aware routing protocol (EARP). Compared to other
estimators, bit errors can directly reflect the wireless channel state and can be used in complex
regions. In this paper, we use parameter VerValue to choose appropriate correction codes and
translate error degree to ER Dis(error distance). We propose local Dijkstra algorithm (LDA) in
ER Dis graph, witch is a distributed routing protocol algorithm and can be easily implemented
in WSNs, to choose a short ER Dis path for very sensor node. Simulation shows that compared
to different routing protocol schemes, LDA can choose an efficient path to the base station and
EARP scheme can indeed greatly reduce transmission energy and prolong WSNs lifetime.
