OPERA: An Optimal Progressive Error Recovery Algorithm for Wireless Sensor NetworksSaad Bin Qaisar and Hayder RadhaDepartment of Electrical and Computer EngineeringMichigan State UniversityEast Lansing, MI-48824, United States Abstract—Wireless Sensor Networks (WSNs) requirerobustness against channel induced errors while retransmissionbased schemes prove too costly for energy constrainedsensor nodes. Channel coding with low rates canensure increased reliability, and it can elim ...
