Unmanned Aeronautical Ad-hoc Networks: Enhancing the Reactive-Greedy-Reactive Protocol and Introducing a New Mobility Model
… we propose the Enhanced Gauss-Markov (EGM) mobility model for UAANET simulations to replace the widely used, but unrealistic, Random Waypoint (RWP) mobility model. Simulations performed using the OPNET simulator show that Optimized-RGR outperforms RGR. There is a 5.3% increase in Packet …

Strain transducers for active control
… sensor(s). The first part of the thesis presents modeling and design studies for a square piezoceramic actuator used to implement a single channel velocity feedback control with a velocity sensor at its center. A fully coupled mobility model of the panel with a square piezoceramic patch actuator …

A New Environment-Aware Framework For The Research of Mobile Ad hoc Networks
… coordinates system. It was noticed that the mobility of mobile nodes could have significant influence on the performance of a network and the environment also must be considered carefully as MANET can be deployed anywhere. The need for a framework to better study MANET was identified. The …
