Figure 11From: Opportunistic routing with in-network aggregation for duty-cycled WSNs with delay requirementsRatio of late packets varying wake-up interval for comparing ORD and ORIA. In the graphs, n is the number of nodes and s is the number of packets generated per 30 seconds. (a)Â n = 200, s = 20. (b)Â n = 200, s = 100. (c)Â n = 600, s = 60. (d)Â n = 600, s = 300.Back to article page
