# On Localized Countermeasure Against Reactive Jamming Attacks in Smart Grid Wireless Mesh Networks
## 5 Localized Trigger Identification Algorithm
### Trigger Nodes Detection Procedure
#### 5.2.2 Identification of a Single Trigger Node (ISTN) Algorithm
In accordance with the assignment of colors on each hexagon, all testing groups within the same color are scheduled to perform the localized identification of trigger devices simultaneously using the sequential GT manner. Besides the analytic proof on the run-time and message complexities, an intensive set of experimental simulations has supported an outstanding performance of our security method on the various configuration of the Smart Grid wireless mesh networks in terms of scalability and stability. In the case that jammer randomly reacts with probability \(p\), the group testing results would be incorrect in identifying the triggers. As a future work, we will propose a more accurate identification algorithm against the random reactive jamming model. Conceptualization, I.S. and M.C. ; Methodology, I.S. ; Writing; I.S. and M.C.
