A Fault Tolerant Trajectory Clustering (FTTC) for Selecting Cluster Heads In Wireless Sensor Networks

Wireless Sensor Networks (WSNs) suffers from the hot spot problem where the sensor nodes closest to the base station are needed to relay more packet than the nodes farther away from the base station. Thus, lifetime of sensory network depends on these closest nodes. Clustering methods are used to extend the lifetime of a wireless sensor network. However, current clustering algorithms usually utilize two techniques; selecting cluster heads with more residual energy, and rotating cluster heads periodically to distribute the energy consumption among nodes in each cluster and lengthen the network lifetime. Most of the algorithms use random selection for selecting the cluster heads.
