Research on SDT Security Scheme for Wireless Sensor Network

A common approach to overcome the limited of sensor networks is to aggregate data relying on intermediate nodes.The pivotal issue is to guarantee end-to-end secureity transmitsion.In the paper, Subsection Data Transport security scheme is presented.Data are safely aggregated relying on multipath routing.The scheme has better security in the simulation.A sensor network can protection against availably eavesdropping, data tampering and Denial of Service attacks even in the presence of compromised nodes.
