MANET has attracted popularity due to the tremendous use of internet and its allied resources, the ease of deployment and features of MANET keeps it ahead in wireless domain and gaining recognition in the networking domain, but it is true that the security is at stake and researchers have to put additional efforts for developing standardize architecture for securing wireless networks. The preventive measures encryption, authentication and cryptography fails to detect newer attacks that leads wireless network more susceptible than wired. Continuous node mobility causes frequent changes in the topology and link state. The noise collision, fading issue and interference are majorly responsible for making the wireless networks more prone to failure. Along with the rigid less infrastructure, the MANET faces the challenge from false positive and false negative for deciding the threshold value-T and intended intruder/malicious nodes with accuracy. The value of ‘T’ should be designed and chosen properly in between the true and false alerts. Along with these, the route optimization also plays very important role in ad hoc network. If there are multiple routes, then optimum path free from malicious nodes must be chosen from source to destination. The research paper mainly focuses on formation of cluster and cluster head, optimum path and designing the Threshold-T.

由于Internet及其相关资源的大量使用，MANET受到了欢迎，MANET的易于部署和功能使其在无线领域处于领先地位，并在网络领域获得认可，但确实存在安全隐患，并且研究人员确实处于危险之中。必须付出额外的努力来开发用于保护无线网络的标准化体系结构。预防措施的加密，身份验证和加密无法检测到较新的攻击，该攻击使无线网络比有线网络更容易受到攻击。连续的节点移动性会导致拓扑和链接状态的频繁更改。噪声冲突，衰落问题和干扰是导致无线网络更容易出现故障的主要原因。随着基础设施的减少，MANET面临来自误报和误报的挑战，难以准确确定阈值T和目标入侵者/恶意节点。“ T”的值应在正确和错误警报之间进行适当的设计和选择。伴随着这些，路由优化在ad hoc网络中也起着非常重要的作用。如果存在多个路由，则必须从源到目的地选择没有恶意节点的最佳路径。该研究论文主要集中在聚类和聚类头的形成，最佳路径以及Threshold-T的设计上。如果存在多个路由，则必须从源到目的地选择没有恶意节点的最佳路径。该研究论文主要集中在聚类和聚类头的形成，最佳路径以及Threshold-T的设计上。如果存在多个路由，则必须从源到目的地选择没有恶意节点的最佳路径。该研究论文主要集中在聚类和聚类头的形成，最佳路径以及Threshold-T的设计上。
