Reliable and Efficient Data Transfer in Wireless Sensor Networks via Out-of-Sequence Forwarding and Delayed Request for Missing Packets

We present a new protocol for lossless data transfer in wireless sensor networks using less time and fewer messages in comparison to the well-known protocol PSFQ (C.-Y. Wan, 2002), without compromising the reliability. The two key features for the better performance of our protocol are out-of-sequence packet forwarding and delayed request for missing packets
