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)
We previously demonstrated that human osteosarcoma cells (SAOS-2) induce contact-dependent apoptosis in endothelium, and expected similar apoptosis in human gingival fibroblasts (h-GF) using SAOS-2 alkaline phosphatase (AP) to identify cells. However, h-GF apoptosis did not occur, despite reduction in AP-negative h-GF number (p < 0.01) and enhancement of(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)
High probability of disappointment in Ad-Hoc networks due to energy-tired nodes is one of the main limitations. If some nodes expire early due to lack of energy, they cannot transfer the data with each other. Therefore, excessive consumption of nodes energy should be prevented. Energy conservation of a Network is a major design issue since mobile devices(More)
