As stated earlier, increasing numbers beacons by structure in the DPE does not improve the localization results.
First is to study the impact of varying beacon transmission frequency (or number of beacons send per second) on the performance.
While the DTIM interval is the same for all the STAs within the network, the beacon period, i.e., the number of beacons transmitted within two consecutive DTIM frames, can be different for each STA.
Let N beacon and T q be the number of beacons and the time to transmit one data packet and receive ACK packet in CAPsudaslength, which can be obtained by Equations 62 and 63, respectively.
If it receives n i b beacon frames from station i among last 1/Tbeacon number of beacons, δ R i is n i b 1 / T b e a c o n.
The deployment effort is measured by the number of beacons to deploy, and the location accessibility to deploy the beacons.
Lower panel depicts a view from within the virtual environment (approaching an intersection), demonstrating the current destination (Find the Pet Store), remaining number of beacons (1), trial number (1/40), compass rose, and the floating beacon (PET STORE 559 m).
However, for the RPE algorithm, the number of beacons increase with the network density, because we ensure that 5%% of the nodes are beacons.
