Age of information and mobility

Age of information is a recently proposed metric that measures the freshness of information at a destination receiving data from an information source. It has become popular in the networking and queuing community, especially for studying delivery of real time status updates. In this thesis, we explore applications of AoI to mobile and adhoc networks. More specifically, we look at two problems - 1) Age optimal information collection and dissemination from locations arranged on a graph, using a mobile agent that travels between them, and 2) Age-based transmission schemes for a group of mobile agents which need to continuously exchange information while moving around in a cell partitioned network. We also derive expressions for age metrics for discrete time queuing systems under various service disciplines, and service and arrival time distributions.
