So in d = 2 this will be squares, in d = 3 this will be cubes. ( , then the RGG has asymptotically almost surely no Hamiltonian cycle and if − A more general analysis of the connection functions in wireless networks has shown that the probability of full connectivity can be well approximated expressed by a few moments of the connection function and the regions geometry. p j {\textstyle H_{ij}=\beta e^{-({r_{ij} \over r_{0}})^{\eta }}} ln ( d {\textstyle {\left\lfloor {1/r}\right\rfloor }^{d}} − 139.59.20.20. ) Cite as.

Additionally, random geometric graphs display degree assortativity according to their spatial dimension[1]: "popular" nodes (those with many links) are particularly likely to be linked to other popular nodes. ⌊ ( / For any β l r The samples are generated by using a random number generator (RNG) on ( 0 − A real-world application of RGGs is the modeling of ad hoc networks. {\textstyle P[X>0]\sim 1-e^{-\mu }} connect with probability given by , the RGG is asymptotically almost surely disconnected.
