摘　　要：针对水下恶劣环境与恶意攻击造成水下传感器连通损坏的问题,提出了一种水下传感器网络自组织连通恢复方法,首先分析水下传感器网络,获得中继节点,并使用该节点确定网络节点的分区和代替节点,然后通过MACRA算法中的模糊连通恢复机制与精准连通恢复机制,将水下传感器网络分割成多种具有一定规则的区域,并对局部区域节点密度计算,凭借计算结果完成传感器网络节点连通恢复,同时为了预防二次损坏情况,拟定阈值进而选取出备用节点,使传感器网络即使遭受二次损坏也能够及时的恢复。仿真结果证明,MACRA算法能够有效实现水下传感器网络自组织连通恢复,并且效率较高,不会浪费过多的资源。This paper proposes a self-organizing connection restoration method in underwater sensor network for solving the connection damage caused by underwater environment and malicious attack.First of all,the underwater sensor network was analyzed to obtain relay nodes.Meanwhile,the node was used to determine the partition and substitute node of the network node.Then,based on the fuzzy connectivity recovery mechanism and accurate connectivity recovery mechanism of the MACRA algorithm,the underwater sensor network was divided into a variety of regular regions,and then the node density of the local area was calculated.Next,the node connectivity recovery of the sensor network was completed by the calculation results.Meanwhile,the threshold was determined for preventing the secondary damage.Finally,the backup node was selected for repairing the damaged sensor network in time.The simulation results show that the MACRA algorithm can realize the self-organized connectivity recovery of underwater sensor networks,and has high efficiency.
