Modern users are accustomed to always-accessible networks ready serve all of their communication, entertainment, information, and other needs, at the touch devices. Spoiled with choices provided on competitive markets, risk customer churn makes network service providers sensitive user Quality Experience (QoE). Services that enable people work industries function in these pandemic times, such as...

Service-Oriented Applications (SOA) are being regarded as the main pragmatic solution for distributed environments. In such systems, however each service responds the user request independently, it is essential to compose them for delivering a compound value-added service. Since, there may be a number of compositions to create the requested service, it is important to find one which its propert...

The integration of SaaS service for group user in cloud is challenging, notably because the service’s QoS and member’s personalization QoS preference in group are uncertain. This is a timely and importance problem with the advent of the SaaS model of service delivery. Therefore, before the SaaS service been utilized, the service alternatives must be ranked for group user based on services’ QoS ...

I am exploring an approach to developing services with multiple user interfaces based on a high level description of the service. The description is made using interaction acts, which are primitives for describing user-service interaction in a device independent way. Device adapted user interfaces are generated based on interaction acts in combination with device and service specific presentati...

In this paper, a multi-user multi-server queuing system is studied in which each user is constrained to get service from a subset of servers. In the studied system, rate allocation in the sense of max-min fairness results in multi-level fair rates. To achieve such fair rates, we propose CMFQ algorithm. In this algorithm users are chosen for service on a packet by packet basis. The priority of e...
