Design of Wireless Sensor Network Security and Solution by MAC Protocol and Topology Control Technology

Wireless sensor network security is the guarantee of the task execution confidentiality, data reliability, data fusion, and the security of data transmission. This paper analyzes security problems in wireless sensor network MAC protocol at present. The aim of topology control is through the transmission range control nodes to generate network topology satisfying certain properties, in order to extend the network life cycle, reduce network interference, improve the throughput. The paper proposes design of wireless sensor network security and solution by MAC protocol and topology control technology. Finally, this paper discusses a new security design of WSN based on more energy-efficient MAC protocol, and the simulation experiment is carried out in NS2 network. Copyright © 2013 IFSA.
