Edge Controller Placement for Next Generation Wireless Sensor Networks

Nowadays, Fog architecture or Edge is becoming a popular research trend to distribute substantial amount of computing resources, data processing and resource management at the extreme edge wireless sensor networks (WSNs). Industrial communication track in next generation for fourth revolution industrial process. Adopting fog into systems promising technology within architecture. With Software Defined Network (SDN) architecture, this paper, we address controller placement as an optimization problem with objective more robustness while minimizing delay network associated synchronization overhead. The provided modelled submodular function. Two algorithms are find optimal solution using real get realistic results. Greedy Algorithm Connectivity Ranking provided. algorithm outperforms connectivity ranking optimum balance between different metrics. Also, based on operator preference, number controllers be placed will This paper plays great role standardization softwarization networks.
