为有效提高水下传感器网络中未知节点的定位效率并降低网络能耗,提出一种改进禁忌搜索算法的Autonomous Underwater Vehicle(AUV)动态路径规划策略.所提出的算法和策略,采用六边形部署算法,寻找合适的虚拟锚节点位置,以达到最佳覆盖效果;然后通过在AUV节点上配置定向天线,获取未知节点方位信息;再次,利用改进的禁忌搜索算法,选定AUV节点下一步目标虚拟锚节点,引导AUV节点移动.该文通过改进的禁忌搜索算法设置两个禁忌集,防止AUV节点重复搜索,并辅助AUV节点移动方向判定,保证未知节点的定位覆盖率.为验证所提策略有效性,对所提该策略和静态路径规划算法中的典型算法Scan算法进行对比分析计算.仿真表明,基于禁忌搜索算法的AUV动态路径规划策略较Scan算法移动路径长度明显减少,虚拟锚节点数目有所降低,能有效降低能耗,延长网络寿命.同时,由于Received Signal Strength Indicator(RSSI)测距法存在误差,误差值设置为虚拟锚节点到未知节点的真实距离的10%,仿真得出基于禁忌搜索算法的AUV动态路径规划策略较Scan算法,定位精度有所提高.
