Increasing the Energy Efficiency of TICK by Selecting Adaptive Forwarding Nodes in Wireless Sensor Networks
Keywords:Wireless sensor networks, SNs, network energy, en route filtering
Time-Based Dynamic Keying and En Route Filtering (TICK) reduces the communication costs for wireless sensor networks by eliminating the exchange of control keying messages. TICK is more energy-efficient and is good at securing events as they occur; it also selects predetermined forwarding nodes for re-encryption operation without considering their residual energy (RE) which causes more energy depletion. We propose an energy- efficient method that selects forwarding nodes for re-encryption with high energy levels and a low hop count (HC). Simulation results indicate that the proposed method achieves better energy conservation.
