A Policy-Based Approach for Managing Ubiquitous Networks in Urban Spaces

Modern cities are becoming increasingly networked environments and a plethora of computing equipment interacts with today\´s urban citizens. We refer to these ubiquitous networked environments as "urban spaces" and attempt to manage these under a unified framework based on policies. Since users actively participate in urban spaces with their owned devices and demand more control and privacy, we introduce a scheme to protect user privacy and respect their preferences. We adopt a multiple manager paradigm to enable more entities to offer their services and cooperatively shape management logic based on their objectives. Detailed policy examples illustrate the concepts and simulation results measure the effect of policies on network performance.
