Dynamic hierarchical communication paradigm for Wireless Sensor Networks : A centralized, energy efficient approach

Effective utilization of limited power resources by the sensors is pre-eminent to wireless sensor networks. Organizing the network into balanced clusters based on assigning equal number of sensors to each cluster may have the consequence of unbalanced load on the cluster heads. By-product of this is unbalanced consumption of energy by the nodes which leads to minimization of network lifetime. We put forth a Sink administered Load balanced Dynamic Hierarchical Protocol (SLDHP) to balance the load on the principal nodes. Hierarchical layout of the sensors endows the network with increased lifespan. Outcome of this protocol also includes substantial saving of the energy consumed by the nodes. Simulation results indicate significant improvement of performance over Base station Controlled Dynamic Clustering Protocol (BCDCP).
