On information technology topics, the word “innovation” is increasingly present every day. Regarding Internet of Things (IoT) subject, it’s no different. Every year new IoT products and services are created presented that allow users to make their lives easier simpler, connecting people devices remotely automatically, generating mobility operability through heterogeneity connected internet. Bas...

State machine replication reduces distributed to centralized computing. Any sequential service, modeled by a state machine, can be replicated over any number of processes and made highly available to all of them. At the heart of this fundamental reduction lies the so called universal consensus abstraction, key to providing the illusion of single shared service, despite replication. Yet, as univ...

The development of computer networks has seen a paradigm shift from static, hierarchical network structures to highly distributed, autonomous systems without any form of centralized control. For networking nodes, the ability to self-adapt and self-organize in a changing environment has become a key issue. In conventional network structures, e.g., the Internet, there is usually a hierarchical or...

the proliferation of information and communications technology (ict) along with the incremental growth in the use of cloud services, enterprise network and data center technologies in recent years, have caused unprecedented expansion of computer networks. however, the existing network architecture was not well designed to meet the requirements of today's needs. one of the most important pr...

this paper deals with the problem of user-server assignment in online social network systems. online social network applications such as facebook, twitter, or instagram are built on an infrastructure of servers that enables them to communicate with each other. a key factor that determines the facility of communication between the users and the servers is the expected transmission time (ett). a ...
