In the formula (3) used to calculate the adaptive beacon interval, parameters a and b define the upper and lower bounds of the period. Could you please clarify how these two parameters are determined? What specific impact do their values have on the overall routing performance? Parameters a and b in Equation (3) are preset design values chosen through simulation tuning rather than calculated in real-time. They define the range within which the adaptive beacon period can vary. A smaller value of a allows the beacon interval to be longer when network conditions are calm, helping to save energy. A larger value of b prevents the beacon interval from becoming too short even when the network is highly active, which avoids excessive control overhead and packet collisions. Together, properly tuned values of a and b enable APID to adjust its beaconing rate efficiently across different mobility and density conditions. This balance helps maintain fresh routing information without wasting energy, contributing directly to APID’s higher packet delivery rate and lower energy consumption compared to protocols with fixed beacon intervals like GPSR and OLSR.
