一种基于CRT序列的DV-hop定位算法

Protocol sequences are deterministic periodic binary sequences with special Hamming cross-correlation properties. They were originally used for channel access in the collision channel without feedback. Furthermore, they do not require stringent time synchronization,channel monitoring or backoff algorithm, and thus have been widely adopted in various communication systems with energy constraints. To address the collision problem in broadcast of a DV-hop algorithm which would yield awful localization accuracy in WSNs, this paper proposes a protocol sequence based DV-hop localization algorithm, and shows by simulation that it significantly outperforms the original one.
