EAPHRN: Energy-Aware PEGASIS-Based Hierarchal Routing Protocol for Wireless Sensor Networks

Abstract. Power management is considered as one of the most critical researching issues in the area of wireless sensor networks (WSN), as it plays the main role in increasing the sensor nodes life time. This paper proposes a new hierarchical routing protocol for stationary wireless sensor networks, called EAPHRN Energy-Aware PEGASIS-Based Hierarchal Routing Protocol for Wireless Sensor Networks (EAPHRN). The proposed scheme attempts to increase both the lifetime and the throughput of the wireless sensor network. The efficiency of proposed protocol is evaluated. The simulation results showed that the EAPHRN protocol can solve the main problems in PEGASIS since it uses a new chain construction algorithm that is completely different that the PEGASIS and is more efficient. It also uses a new chain leader election method that plays a very critical role in the energy saving
