Minimizing energy consumption in transmit-only sensor networks via optimal placement of the cluster heads

Abstract

This paper tackles the energy consumption minimization in transmit-only Wireless Sensor Networks and castes it as a convex optimization problem that is solved efficiently by an SOCP solver. The problem focuses on finding the optimal placement of cluster head nodes within the deployment field that minimizes the energy depletion while meeting network's coverage and connectivity requirements. Simulation results showed that reduction in energy consumption in a range of (16-24)% can be achieved by employing the optimization-based approach as compared to other standard placement methods.
