Research on the Application of Security Algorithms in Wireless Sensor Networks

The energy consumption incurred by security algorithms has negative impact on the lifetime of sensor nodes and the whole network. In order to get a tradeoff between network security and availability, this paper first introduces the related technologies on measuring the energy cost of security algorithms.Then the energy cost of some security algorithms on Crossbow node is measured. It is of benefit to know about the effect of security algorithms on the energy cost of nodes in WSN. In the end some guidelines for application of security algorithms in wireless sensor network are proposed based on the analysis of the measuring results and it is of benefit to the application of security algorithms in WSNs.
