Faced with increasing energy prices, financial crisis, and environmental problems, the sector of increation and communications technologies initiates the third industrial revolution. This revolution aims to intelligently allocate and distribute energy. The study, development, and implementation of intelligent energy managers for computer networks are called Green Networking. The proposed project aims to develop and test an energy-aware solution. In this, an energy-efficient topology control algorithm named EALSP. The algorithm first tries to preserve the minimum-energy paths. However, when a node searches its requirement a large transmission power to cover some of its neighbors, it capitalizes two-hop paths to reach them instead of using single hop. Simulation results show that EALSP can effectively decrease the transmission power and reduce the energy dissipation when transmitting. This paper presents an energy efficient routing scheme for wireless sensor network to apply GREENNET work protocol by clustering. This is based on the PSO algorithm, which is designed so that it automatically selects the desired nodes. This protocol looks after both the energy efficiency as well as transmission distance. In this paper, we compare different parameters varying selected parameters and observed the simulated result.
