Applications consisting of messaging, voice, and video are used to provide situational awareness to decision makers and emergency responders in high criticality crisis scenarios such as disaster management. Here, ad hoc wireless networks are often quickly provisioned to provide the necessary connectivity to support these applications. Applications ill prepared to deal with the constant fluctuation...
In high criticality crisis scenarios, such as disaster management, ad hoc wireless networks are quickly assembled in the field to support decision makers through situational awareness using messaging-, voice-, and video-based applications. These applications cannot afford the luxury of stalling or failing due to overwhelming bandwidth demand on these networks as this could contribute to overall mission...
Finding maximum likelihood parameter values for Finite Mixture Model (FMM) is often done with the Expectation Maximization (EM) algorithm. However the choice of initial values can severely affect the time to attain convergence of the algorithm and its efficiency in finding global maxima. We alleviate this defect by embedding the EM algorithm within the variable Neighborhood Search (VNS) methaheurestic...
