Analysis and design of energy-oriented security protocols for Wireless Sensor Networks

In this paper, we first review the architecture of the Wireless Sensor Networks (WSN), and then the communication protocol stack and other technical backgrounds are analyzed, providing theoretical basis for further study of WSN routing protocols and algorithms. On energy supply, the paper studies how to improve the network life cycle by effective use of node energy, an event-driven clustering routing algorithm is proposed; in terms of security, against the popular belief that public key cryptographic schemes are not practical for sensors, a secure network communication mechanism based on ECC is proposed. Finally, the simulation results show the efficiency of event-driven clustering routing algorithm; and the energy loss of the security mechanism is analyzed, thereby we can ensure the security of communication in the context of saving energy.
