“…The work In addition to the aforementioned categories, [22] describes mobile code paradigms with regard to network security vulnerabilities. Following these definitions and paradigms there are several centralized [23], [24] and decentralized [25], [26] approaches available to implement code mobility. Especially the approach proposed in [25], where Arden et al describe a decentralized computing platform for running mobile code, based on explicit policies for confidentiality and integrity, will be further investigated in the context of our scenario and possibly applied as one of the migration techniques.…”

The advent of the Smart City domain has led to the creation of massive amounts of diverse data. Stakeholders in this domain need to be able to analyze this data in order to make informed planning decisions. To address this complex task, Distributed Analytical Environments (DAEs) have emerged. These environments consist of different distributed analytical and data services, which are composed in a dynamic way to deliver insights that are crucial for stakeholders. Since these environments deal with business critical and sensitive information, strict compliance constraints apply. These constraints lead to situations where certain concrete services are not allowed to exchange data, even though their interaction is necessary to produce the desired results. Finding a valid solution in the space of possible instantiations is a non-trivial problem. In this paper we introduce Nomads, a framework that enables service mobility in such constrained dynamic composition environments to overcome aforementioned restrictions. The framework improves the overall satisfiability and therefore also the quality of constrained DAEs. We outline the requirements of a representative DAE scenario, provide a detailed problem formulation, and then discuss the service mobility framework along with our solution finding algorithm. The evaluation demonstrates that the Nomads framework considerably increases the number of successfully performed compositions even in highly constrained environments.

“…How to adapt the protocol inside one protocol domain is a key issue. In [14], Fractal, a dynamic application level protocol adaptation approach has been proposed. It uses the mobile code technology for protocol adaptation and leverages existing content distribution networks (CDN) for protocol adaptors (mobile codes) deployment.…”

“…These approaches need some changes to the existing infrastructure for their deployment. Fractal [14] solves the deployment problem by leveraging the existing CDNs technology to distributed protocol adaptors, which are implemented using mobile code. All these previous work complements to our work very well.…”
