    Sum-Product Based Optimization for Scalable Video Streams in Peer-to-Peer Mesh Network

    Receiver heterogeneity of a P2P network can be effectively addressed by scalable video streams. Due to the discontinuous nature of scalable video, traditional convex-optimization approach is not applicable. The authors propose a message-passing based approach for optimization using the sum-product update algorithm. Advantage of this simple but elegant approach over...

    A Model-Driven QoS Provisioning Engine for Cyber Physical Systems

    Developing cyber physical systems is hard since it requires a coordinated, physics-aware allocation of CPU and network resources to satisfy their end-to-end Quality-of-Service (QoS) requirements. This paper provides two contributions to address these challenges. The authors present model-driven middleware called NetQoPE that shields application developers from the complexities of programming...

    Automating Middleware Specializations for Fault Tolerance

    General-purpose middleware solutions, by definition, cannot readily support domain-specific semantics without significant manual efforts in specializing the middleware. This paper presents GRAFT (GeneRative Aspects for Fault Tolerance), which is a model-driven, generative, and aspects-based approach to specialize general-purpose middleware with failure handling and recovery semantics imposed by a domain. Model-driven...

    A Generative Middleware Specialization Process for Distributed Real-Time and Embedded Systems

    General-purpose middleware must often be specialized for resource-constrained, real-time and embedded systems to improve their response-times, reliability, memory footprint, and even power consumption. Software engineering techniques, such as Aspect-Oriented Programming (AOP), Feature-Oriented Programming (FOP), and reflection make the specialization task simpler, albeit still requiring the system developer to manually identify...

    Maximizing Service Uptime of Smartphone-Based Distributed Real-Time and Embedded Systems

    Smartphones are starting to find use in mission-critical applications, such as search-and-rescue operations, wherein the mission capabilities are realized by deploying a collaborating set of services across a group of smartphones involved in the mission. Since these missions are deployed in environments where replenishing resources, such as smartphone batteries, is...

    Middleware Specialization for Product-Lines Using Feature-Oriented Reverse Engineering

    Supporting the varied software feature requirements of multiple variants of a software product-line while promoting reuse forces product line engineers to use general-purpose, feature-rich middleware. However, each product variant now incurs memory footprint and performance overhead due to the feature-richness in addition to the increased cost of its testing and...
