— Reducing energy consumption has been a recent focus of wireless sensor network research. Topology control explores the potential that a dense network has for energy savings. One such approach is Geographic Adaptive Fidelity (GAF) [1]. GAF is proved to be able to extend the lifetime of self-configuring systems by exploiting redundancy to conserve energy(More)
Reliability and security concerns have increased demand for Virtual Private Networks (VPNs). Ideally, a VPN service should offer autonomous overlay networks with guaranteed bandwidth allocations over a shared network. Network providers seek an automated VPN creation and management process, while users of a VPN would greatly benefit from secure control over(More)
A video coding scheme based on the wavelet transform and designed for ATM networks was developed. The traac generated from the encoder was analysed and used to conngure the network parameters. Initial experiments have been based on a single frame, and have shown the calculations required to conngure a packet based, continuous bit rate stream, and a variable(More)
