This document discusses improving energy efficient and secure multipath communication in underwater sensor networks. It proposes using Hamming coding based segment combination and localization to prevent wormhole attacks. The key points are:
1) Underwater sensor networks face challenges like high bit error rates, long delays, and low bandwidth. Multipath communication with forward error correction can improve reliability but still has issues.
2) The proposed approach uses Hamming coding on packet segments, combines segments at the destination, and uses localization to detect wormholes.
3) Simulation results show the proposed approach reduces packet error rates and energy consumption compared to single path and multipath approaches without segment coding.
