Reliable and Energy-Efficient Two Levels Unequal Clustering Mechanism for Wireless Sensor Networks

Presentation / Conference
Ali, A. E., Al-Dubai, A., Romdhani, I., & Eshaftri, M. (2018, June)
Reliable and Energy-Efficient Two Levels Unequal Clustering Mechanism for Wireless Sensor Networks. Paper presented at The 16th IEEE International Conference on Smart City (IEEE SmartCity-2018), Exeter, UK
In Wireless Sensor Networks, clustering sensor nodes into disjoint groups is widely used to achieve load balance and increase network lifetime. In particular, traditional uneq...
