Traffic Change Detection Clause Samples

Traffic Change Detection. Consider graphs and with set of edge weights and . The relative amount of change over period ▽t = | - | between edges is given by d (g, g|). For any non-zero weights and u,v∈ V, the traffic change between u and v as the traffic graph evolve from g to g| is thus: |ω(u,v) -ω|(u,v)| (14) Clearly max(ω(u,v) ,ω|(u,v)) >= |ω(u,v) -ω|(u,v)|. And the transformation: d(g,g¢) = å (15) w (u, v) - w ¢(u, v) max(w (u, v),w ¢(u, v)) u,vÎV normalizes the traffic change over all the edge sets in V. Once a significant change is detected in the graph, the next stage is started.
