For the k-th node SNIR is given by (1), where S is the desired signal power in [W], kB-Boltzman's constant in [J/K], T-ambient temperature in [K], BW-channel bandwidth in [Hz], NF-Noise Factor [-], M-the total number of network nodes, whereas the last term in the denominator denotes the sum of radiations from all other nodes in the network (excluding, of course, the radiation from the k-th node for which SNIR is being calculated as well as an m-th node to which the transmission is addressed)
Staniec) used for: a) generating random node distribution scenarios (ten scenarios for each number of nodes M, where M was varied from 10, 20 up to 100) to be fed into the Matlab scripts and b) calculating SNIR based on the output files generated by the Matlab scripts (as above).
A set of curves has been obtained-each representing SNIR averaged over all generated scenarios for each particular value of M.
A proposed formula for SNIR as a function of antenna beamwidth and network population
For initial visual verification, three of the resultant modeled SNIR curves were graphically presented in for three selected values of M in fig.
The final aim the investigations presented in this section was, therefore, to determine and evaluate of a general closed-form formula relating SNIR to [[theta].
The simulations of SNIR were performed in 5[degrees] steps over the entire range of angles, which gave the total of 72 samples.
3dB], M) from the generalized model using (4) along with its parameters in Table 1, and comparing it with individual SNIR curves obtained in the original simulations.
Therefore, according to (7), (8) and (9), the received SNIR at the [SR.
Here, we assume [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] and SNIR varies from 0 dB to 18 dB.
6, we show the outage probability of the primary system as a function of SNIR in dB.
Best cooperative secondary node is selected based on SNIR between the links PTx-to-[ST.
