Context-Aware Service Delegation for Opportunistic Pervasive Computing

The growth of capabilities of mobile devices allows them to host increasingly sophisticated application services. Emerging paradigms within the Cloud Continuum are based on the concept of running services closer to users, even on their own devices. Nonetheless, running collaborative services on these devices requires attention to constraints that differentiate the devices from cloud servers, such as limited battery or constrained data plans. New techniques are required to empower users to, first, execute services locally and, second, allow services to migrate to other available devices. We define Pervasive Delegation Of Services (PODS), a framework to opportunistically select the best candidate to run a service from among those in a local network, as well as to delegate it to others whenever the contextual circumstances change.
