PPR: Partial Packet Recovery for Wireless NetworksKyle Jamieson and Hari BalakrishnanMIT Computer Science and Artificial Intelligence Lab{jamieson, hari}@csail.mit.edu AbstractBit errors occur over wireless channels when the signal isn’t strong enough toovercome the effects of interference and noise. Current wireless protocols may useforward error correction (FEC) to correct for some (small) number of bit errors,but generally retransmit the whole packet if the FEC is insufficie ...
