Adaptation o/the Fixed Point Approximation to Ad Hoc Networks Chapter 5 The 2% blocking criteria is achieved with an arrival rate of less than 0.226 calls/s per node pair for the simulation and less than 0.217 calls/s per node pair for the analytical model, which is an error of 3.9%. For blocking below the 2% level the simulation results appear to oscillate between 0.18 calls/s per node and 0.22 call/s per node. While it is difficult to explain this phenomenon, the errors obtained when comparing the analytical results to simulations can most likely be attributed to the assumptions made with regard to the signal propagation and the use of a Gaussian distribution for the estimation of the interference distribution.

Adaptation o/the Fixed Point Approximation to Ad Hoc Networks Chapter 5<br />
The 2% blocking criteria is achieved with an arrival rate of less than 0.226 calls/s per<br />
node pair for the simulation and less than 0.217 calls/s per node pair for the<br />
analytical model, which is an error of 3.9%. For blocking below the 2% level the<br />
simulation results appear to oscillate between 0.18 calls/s per node and 0.22 call/s per<br />
node. While it is difficult to explain this phenomenon, the errors obtained when<br />
comparing the analytical results to simulations can most likely be attributed to the<br />
assumptions made with regard to the signal propagation and the use of a Gaussian<br />
distribution for the estimation of the interference distribution.<br />
Figure 5-9 and Figure 5-10 show the stationary distribution of calls in progress at<br />
nodes 3 and 9 for mean arrival rates of 0.1 and 0.9 calls/s per node pair respectively,<br />
which are obtained by plotting Pn(k) for n c {3,9} and O
