A Novel Data Collection Approach for Wireless Sensor Networks Powered with Ambient Energy

摘要

Wireless sensor networks have become the preferred solution in many applications. The main restriction in using wireless sensor nodes is that the power source of the sensor nodes is limited, as these sensors usually rely on batteries. Typically, a wireless sensor network (WSN) deploys a large number of sensors. When the sensors' batteries run out, they need to be replaced. The replacement process is a costly process. Using ambient resource such as solar, wind, etc. to power a wireless sensor network is a promising solution. In this paper, a Data Collection Energy-Efficient Routing Protocol with Harvested Energy is proposed. The node's reaming energy, energy harvesting rate, packet data rate and node capability are key parameters that are considered to build an efficient tree for collecting data. Extensive simulation experiments have been conducted using NS-3 to study the behavior of the proposed algorithm. The simulation results demonstrate the effectiveness of the proposed approach and its outstanding performance compared to AODV.
