Sector Based Multi-Hop Clustering Protocol for Wireless Sensor Networks

Minimization of energy consumption is a critical design requirement for most Wireless Sensor Networks (WSNs) applications. WSNs are composed of small, energy constrained sensor nodes. The random deployment of sensor nodes in many applications requires unattended operation. The primary goal of WSNs is how to collect sensed information in energy efficient way since the energy is limited. The network lifetime is extended by hierarchical network clustering. In these networks, the sensor field is partitioned into small regions called clusters.
