A Lower Energy-aware-based Routing Protocol Oriented to Internet of Things

As energy of reader in Internet of things is limited, we can only decrease energy overhead of protocol and balance energy consumption among readers to extend the network lifetime as much as possible. Combining with characteristics of Internet of things and requirements of low-energy, energy-aware-based routing protocol was selected for wireless networking of readers. Three methods dealing with how to decrease the energy and how to prolong the wireless network's life expectancy are proposed in this paper. They are power mode switch based on power control, data mining technique as well as indefinite prolonged transmission. Based on these low-energy measures, improved energy-aware-based routing protocol was designed and performance was simulated for analysis. Simulation results show that improved protocol is superior to original one in aspects of total energy cost and network lifetime.
