Abstract:

The authors analyzed the security in WSNs, proposing a novel security algorithm based on biological immune principles. Intrusion characteristic library was established, so as to provide security system  with the functions of memory and learning. Uncertainty and imperfection of information are solved by  using the rough set in WSNs. The simulation results show that the proposed algorithm is feasible and superior to the existed others.
