首发时间:2016-05-06
摘要:协议序列是一种具有良好互相关特性的确定性二进制周期序列,最早用于无反馈冲 突信道的信道接入控制。因其无需信道反馈、退避算法及时钟同步,近年来被广泛应用于众多对能耗有严格要求的通信系统。本论文针对无线传感网 中DV-hop 定位算法由于数据广播过程碰撞频发而导致定位精度降低的问题,提出一种基于CRT 协议序列的DV-hop 定位算法,并对其降低定位误差的有效性进行了仿真验证。

A CRT Sequences Based DV-hop Algorithm
Abstract: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.
Keywords: Wireless sensor networks localization algorithm protocol sequences
