Wireless Sensor Networks have been organized for various aspects like, data collection, security, tracking, military applications etc. But one of the major challenges in Wireless Sensor Network (WSN) that is yet to be sorted out is the lack of energy efficiency which retards the lifetime of the network. Clustering or Hierarchical routing is good solution for reducing much of energy consumption in...
One of the major issues in wireless sensor network is developing an energy-efficient routing protocol. LEACH is very energy-efficient routing protocol based on the clustering of the sensor nodes. However, energy consumption of nodes tends to become uneven in LEACH. HEED improves the LEACH clustering algorithm by using information of residual electric power of nodes. Although HEED provides better performance...
Clustering is an effective approach to enhance performance in large-scale wireless sensor networks. SMCA (small-world model based clustering algorithm), a new clustering algorithm for wireless sensor networks is proposed in this paper, with high clustering coefficient and fault-tolerant properties. SMCA selectively remove some links in a virtual way by the analysis of the edges' clustering coefficient...
