Optimal Decision Number of Times for Search by Approach and Departure with RSSI

To study to take the right information from fluctuated data, we take a scenario of searching the signal source by the received signal strength indicator (RSSI). We proposed the moratorium steps for the decision (MSD) to protect the decision until the defined number of times. The evaluation was simulated with fluctuated RSSI and two wireless nodes were simulated. One node broadcasted the signaling and another node received this signaling and measured RSSI. During the moving, RSSI was measured per regular distance. Due to observing the RSSI's increasing multiple times in a row or de-creasing multiple times in a row, the decision can make whether to approach to the signal source or not. In the simulation, the proposed method and the existing proposal were implemented, and the delay performance was compared. As a result, the proposed method was obviously a higher performance of about a maximum of 30 times. Therefore, it was evaluated that it could be good to protect the decision until the defined number of times taking the right information from fluctuated data
