In the comparison, we also factor in the difference in network topologies, the use of a MAC protocol in the simulation-based study (which is absent in our real deployment), and the random mapping from signal strength to waiting time in our real experiments (while simulations used a deterministic mapping see Section 4.1).
Hence, the 5th percentile SE of real MBS deployment lies in between the two bounds of hexagonal grid and random deployments.
Small cells such as femtocell access points are also extensively modeled by PPP, mainly due to their uncoordinated and random deployment [15].
The deployment of information coverage and random coverage was conducted by using the sensor density relation, and the upper bound value of probability was given to calculate that of information coverage and the events [13].
The authors examine both distance-based and nearest neighbor-based versions of local vote algorithm for grid and random sensor deployments and show that in many situations, for a fixed system false alarm, the local vote correction achieves significantly higher target detection rate than the decision fusion based on uncorrected decisions (see Fig. 1).
The prospect of the police, who will be protecting the convention with measures that include road closings, a huge deployment of bomb-sniffing dogs and random searches on public transportation, engaging in street protests is among the factors that make the security situation here unusual.
Arrays with sparse and random sensor deployment are known to be capable of delivering high quality far-field images without grating lobes.
Figures 5 and 6 show the tracking performances of the proposed tracking scheme using particle filter for grid-based and random node deployment strategies, respectively.
Before the deployment, the BS uses HK and random number to generate a subkey, and then uses and to generate a key-chain for each H-sensor as shown below: (1).
