Abstract

Cluster based routing protocols forWireless Sensor Networks (WSNs) have been widely used for better performance in terms of energy efficiency. Efficient use of energy is challenging task of designing these protocols. Energy holes are created due to quickly drain the energy of a few nodes due to nonuniform node distribution in the network. Normally, energy holes make the data routing failure when nodes transmit data back to the sink. We propose Energy-efficientHOle Removing Mechanism (E-HORM) technique to remove energy holes. In this technique, we use sleep and awake mechanism for sensor nodes to save energy. This approach finds the maximum distance nodes to calculate the maximum energy for data transmission. We consider it as a threshold energy Eth. Every node first checks its energy level for data transmission. If the energy level of node is less than Eth, it cannot transmit data.
