For ease of exposition, PT, SR, ST and PR are assumed to be collinear and the distance between ST(1) and ST(2) is assumed to be much smaller than the distance between the other system nodes, thus d2 ≈ d8, d3 ≈ d4 and d5 ≈ d6.
In particular, the behaviour of the P FA values of the multichannel NAMF, for each Doppler bin, seems to adapt to the less favourable between the two system nodes.
The load balancing consists in distributing the load evenly between system nodes.
It tries to distribute the load (that is, jobs to process) evenly between system nodes and to minimize the mean job response time.
Representing a complex system as a graph means turning the elementary units of the system into nodes, while links between nodes indicate their mutual interactions or relations.
The typical distance between high-voltage power transmission system nodes is about 100 km.
It is assumed that the system network nodes lie on a plane coordinate system Oxy, and the distance between node A and node B is normalized to 1. Therefore, for simulation purposes, the two secondary terminals are placed at A[0; 0], B[1; 0], PU-Tx[0; 1], and PU-Rx[1; 1], respectively, and the relay node is located at R[0,5; 0].
The values for system node states range between 0 (inactive) and 1 (active).
In the study of the Internet and World Wide Web [1, 7] and more generally complex systems such as airline routes, electric power grids, and disease propagation [8], the diameter of a system, which is the average length of the shortest paths between any two nodes in the system, was analyzed when nodes were removed according to the number of links they have; nodes with more links were removed first.
In these systems, a large number of nodes are connected with relatively few links and short paths between the nodes, and each node may execute the same communication software without modifications.
