centrality[1] Degree centrality shows how much a node connected with other nodes. For a node if more the number of direct connections with other nodes more the Degree centrality will be. Greater Degree centrality supports the chances of node to be active. To calculate Degree centrality let N is the set of all nodes in the network ‚ Degree centrality Cd of any node i then where (i‚ j) representing a link between node i and node j. n is the total number of nodes in the network.

In testing for the calibration of speed‚ the values in trial 1‚ 2 and 3 were very similar to the adjusted level of speed on the treadmill. The speed level in trial 1 was 1.0 mph‚ which yielded a measured value of 1.06 mi/hr. Trial 2 was 3.0 mph‚ which yielded 3.2 mi/hr and tiral 3 was 4.0 mph‚ which yielded 4.3 mi/hr.
