A Review of Routing Protocols in Energy Harvesting Wireless Sensor Networks

Abstract

AbstractWith the development of wireless networks in recent years, battery-powered wireless sensor networks are gradually moving towards energy harvesting wireless sensor networks. Energy harvesting technology overcomes the problems of limited energy and difficulty in replacing batteries in traditional wireless sensor networks, and is therefore widely used in various fields. In an energy harvesting wireless sensor network, due to time, space, location, placement angle, energy source, technology, etc., the energy that each sensor node can collect is also different. And nodes with different energy will affect the network life, or data loss occurs on some nodes. Therefore, for this type of network, it is very important to improve and optimize energy usage across the entire network. This article mainly introduces the existing routing protocol optimization algorithms in this type of network. It summarizes studies, analyzes, finds the advantages and disadvantages, and further optimizes ideas for this type of research.KeywordsWireless sensor networkEnergy harvestingRouting protocol
