Network Centrality: An insight for gateway designation in real-time wireless sensor networks
Ref: CISTER-TR-210607 Publication Date: 28 to 29, Jun, 2021Abstract:
This research explores the notion of network centrality as a criterion to designate a node as sink or gateway in real-time wireless sensor networks (WSN). Since centrality is a quantitative measure of how important a node is with respect to others in a given network, we propose to designate as gateway the node with the highest centrality measure. To this purpose, four classical centrality metrics from social network analysis are evaluated, namely, (i) degree centrality, (ii) closeness centrality, (iii) betweenness centrality, and (iv) eigenvector centrality. Simulation results under varying configurations show that using network centrality as a gateway designation criterion is, in general, an effective and promising approach to improve schedulability in WSNs.
