It is imperative to provide service consumers with facilities for selecting required web services according to their Quality of Service (QoS). Several heuristics, which are local adaptation preemptive strategy, elitist perturbation guiding strategy and global tournament strategy for directed local fine-tuning, and a hybrid clonal selection algorithm (CSPLPT) are proposed for QoS-aware web servi...
Original scientific paper This paper presents an architecture for providing quality of service (QoS) and mobility-aware telescreen services in vehicular networks, named "in-vehicle telescreen" (IVT). Providing seamless imagery effect is a key challenge in the distribution of high-resolution and delay-sensitive infotainment IVT services under mobile and varying network conditions. In the IVT arc...
With the emergence of ad hoc networking technology came efforts to provide necessary security support for ad hoc networks. However, due to challenging characteristics of ad hoc environments, providing the same level of security as in wired networks is often very difficult if not impossible. A more viable way to approach this challenge is to maximize the utility of the achievable security instea...
Automated Web Service Composition has gained a significant momentum in facilitating fast and efficient formation of business-to-business collaborations where an important objective is the utilization of existing services to respond to new business requirements in a timely manner. In this context, the service delegation problem can be formulated as follows: When a user poses a sequence of reques...
The article tackles the problem of quality of service assurance in photonic networks. The idea of multi-service photonic network model with the coexistence of optical circuit and packet switching mechanisms and cell communication is used as a basis for service differentiation in the optical domain. Cell loss ratio as a key performance indicator determines the required optical switching mechanis...
The paper presents a quality of service aware routing protocol which provides low latency for high priority packets. Packets are differentiated based on their priority by applying queuing theory. Low priority packets are transferred through less energy paths. The sensor nodes interact with the pivot nodes which in turn communicate with the sink node. This protocol can be applied in monitoring c...
Since the cloud paradigm becomes increasingly popular for dynamic resources allocation, the flexibility of a cloud is still limited regarding network services and their autonomous federation between different providers. The following architectural approach introduces a generic layered model to orchestrate and federate heterogeneous networks. In particular, an architecture is presented that enab...
