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...

Requirements of distributed mobility management draft-ietf-dmm-requirements-01 Abstract The traditional hierarchical structure of cellular networks has led to deployment models which are heavily centralized. Mobility management with centralized mobility anchoring in existing hierarchical mobile networks is quite prone to suboptimal routing and issues related to scalability. Centralized function...

In the latter part of the 1990s, many companies have worked to foster a 'matrix' style culture through several changes in organizational structure. This type of culture facilitates communication and development of new technology across organizational and global boundaries. At Glaxo Wellcome, this matrix culture is reflected in an automation strategy that relies on both centralized and decentral...

| A design framework for space-time multiuser detectors is introduced based on the recently introduced notion of canonical space-time coordinates (CSTC). The CSTC system employs a xed set of basis signals which eliminates the need for estimating direction of arrivals (DOAs) and delays of the channel, thereby allowing signiicant reduction in receiver complexity. The proposed framework is based o...

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...

Cyber-physical systems (CPSs) are emerging future engineered systems with combined efforts in cybernetics and advanced physical components. They are often designed for large and missioncritical systems, e.g., smart grids. The continuous availability of functionality is one of the important concerns by CPS stakeholders. Currently CPSs are still vulnerable to major disruptions. In this research w...

In this paper we present a multi-key index model that enables us to search a record with more than one attribute values in distributed database systems. Indices provide fast and efficient access of data and so become a major aspect in centralized database systems. Most of the centralized database systems use B+ tree or other types of index structures such as bit vector, graph structure, grid fi...
