A Key Distribution method for Reducing Storage and Supporting High Level Security in the Large-scale WSN
In WSNs, since the attacks, such as jamming or eavesdropping without physical access, easily occur, security is one of the important requirements for WSNs. The key pre-distributio...

Distributed Turbo Coding With Soft Information Relaying in Multihop Relay Networks
It has been shown that distributed turbo coding (DTC) can approach the capacity of a wireless relay network. In the existing DTC schemes, it is usually assumed that error-free deco...
