Abstract. Wireless Sensor Networks are edging closer to widespread feasibility with recent research showing promising results in developing and adapting new mechanisms to suit thei...
Electronic collaboration among devices in a geographically localized environment is made possible with the implementation of IEEE 802.11 based wireless ad hoc networks. Dynamic na...
Traditional security systems are not easily scalable and can become single points of failure or performance bottlenecks when used on a large-scale distributed system such as the I...

Traditional key pre-distribution schemes in sensor and ad hoc networks rely on the existence of a trusted third party to generate and distribute a key pool. The assumption of a sin...
The distribution of the wavelet coefficients in 2-D discrete wavelet transform (DWT) subspaces can be well described by a Gaussian mixture statistical model. In this paper, a secr...
