A: 如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点
未知节点利用邻居锚节点进行定位，没有邻居锚节点的未知节点无法定位。
B:
如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点
未知节点一旦被定位就充当起锚节点的功能，向周围邻居发送自己的估计坐标信息
未知节点把已经定位的未知节点与锚节点同等对待

如果接受节点接收到的包数目与发送节点发送的包数目的比值大于CM_threshold,则这两个节点视为邻居节点
有邻居锚节点的未知节点只利用邻居锚节点进行定位，没有邻居锚节点的未知节点才利用已经定位了的邻居未知节点进行定位。-WSN centroid localization algorithm Centorid Algorithm
A: If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors
Unknown node using the neighbor anchor nodes to locate, no neighbors anchor nodes and unknown nodes can not be located.
B:
If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors
Unknown nodes are positioned on as soon as the function of anchor nodes to send their neighbors estimated coordinate information
Unknown unknown node to node already positioned anchor nodes treated equally
C:
If you accept the received packet node number and the number of packets sent by the sending node ratio greater than CM_threshold, then these two nodes as neighbors
Of the unknown neighbor anchor node the neighbor nodes are only positioned anchor nodes, Platform: |

Description: Localization issue is a crucial part of Wireless Sensor Networks (WSNs) including Underwater WSNs (UWSNs). Unlike in Terrestrial WSNs where the localization techniques are well established, localization for UWSNs is still at the infancy stage. Most of the existing localizations proposed are based on Time of Arrival (ToA) and many of them assume an ideal environment and precise synchronization among sensor nodes. This research has proposed a new localization technique for UWSN based on Received Signal Strength Indication (RSSI) Platform: |

Description: In this paper, we propose a robust and low-complexity
acoustic source localization technique based on time differences of
arrival (TDOA), which addresses the scenario of distributed sensor
networks in 3D environments. Network nodes are assumed to be
unsynchronized, i.e., TDOAs between microphones belonging to
different nodes are not available. We begin with showing how to

Description: we investigate the detection of multi-path signal propagation in a Time Difference of Arrival (TDOA) localization scenario. Usually, TDOA measurements are obtained by determining the absolute maximum of the cross correlation function of signals recorded at different sensor nodes in a sensor network. Multipath signal propagation causes multiple peaks in the cross correlation function which lead to erroneous emitter localization. We use hypotheses of possible multipath signal propagation calculated from the autocorrelation functions to identify the line of sight (LOS) peak in the cross correlation function of a sensor pair.
