【摘要】：在無(wú)線傳感網(wǎng)絡(luò)節(jié)點(diǎn)定位中,惡意錨節(jié)點(diǎn)的出現(xiàn)會(huì)降低網(wǎng)絡(luò)定位性能,為了解決這個(gè)問(wèn)題,根據(jù)節(jié)點(diǎn)定位過(guò)程中的惡意錨節(jié)點(diǎn)攻擊特性和定位計(jì)算中的殘差問(wèn)題,提出一種基于殘差分析和過(guò)濾的無(wú)線傳感網(wǎng)絡(luò)安全定位算法。建立了基于距離的安全定位模型,對(duì)網(wǎng)絡(luò)定位中的殘差問(wèn)題進(jìn)行了分析,并且通過(guò)殘差特性過(guò)濾掉網(wǎng)絡(luò)中惡意錨節(jié)點(diǎn),利用剩余錨節(jié)點(diǎn)信息和梯度下降法對(duì)未知節(jié)點(diǎn)實(shí)現(xiàn)高精度定位。仿真表明,此算法在多個(gè)性能指標(biāo)下都能取得相對(duì)較高的定位精度,并且在高強(qiáng)度的惡意攻擊下也能保持較高的定位性能。此算法不但能有效地抵御惡意攻擊對(duì)節(jié)點(diǎn)定位的破壞,還顯著地加強(qiáng)了網(wǎng)絡(luò)的定位安全性。
[Abstract]:In the location of wireless sensor network nodes, the appearance of malicious anchor nodes will reduce the performance of network location. In order to solve this problem, a wireless sensor network security location algorithm based on residual analysis and filtering is proposed based on the attack characteristics of malicious anchor nodes and the residual problem in location calculation. The distance security location model is used to analyze the residual problem in the network location, and filter the malicious anchor nodes in the network through the residual characteristics, and use the residual anchor node information and the gradient descent method to locate the unknown nodes with high precision. The simulation shows that the algorithm can obtain relatively high positioning precision under the multi personality index. The algorithm can also maintain high positioning performance under high intensity malicious attacks. This algorithm can not only effectively resist the damage of malicious attacks on node location, but also significantly enhance the location security of the network.
