Ubiquity of applications supporting the networked society demands an efficient communication system to support Machine Type Communication (MTC) devices. The current architecture is not optimized for MTC traffic patterns and therefore, may lead to excessive signaling. In this paper, we propose a simplified approach to wireless connectivity to cope with the requirements of Massive MTC devices. The essence...
Out of various research challenges present in Cyber Physical Systems(CPS) resource provisioning, service composition and autonomics of self management are considered in detail. Resource provisioning means making the resources seamlessly available to user as and when they are required whereas Service composition means building a complex service when the individual service alone are not sufficient....
Nowadays, mobile operators face the challenge to sustain the future data tsunami. In fact, today's increasing data and control traffic generated by new kinds of network usage puts strain on mobile operators', without creating any corresponding equivalent revenue. In our previous work, we analyzed the 3GPP LTE/EPC architecture and showed that a redesign of this architecture is needed to suit future...
The cloud computing landscape has recently developed into a spectrum of cloud architectures, leading to a broad range of management tools for similar operations but specialized for certain deployment scenarios. This both hinders the efficient reuse of algorithmic innovations within cloud management operations and increases the heterogeneity between different management systems. Our overarching goal...
3rd Generation Partnership Project (3GPP) proposes relay architecture to extend the coverage and enhance the system capacity of Long Term Evolution Advanced (LTE-A). In the relay architecture, the header compression mechanism called RObust Header Compression (ROHC) is introduced to eliminate packet overhead and provide better spectral efficiency for IP packet transmission over the radio. However,...
To address shortcomings of the current Internet, many researchers are taking a clean-slate approach toward re-designing the Internet. These so-called clean-slate approaches discard the old assumptions, design principles, and constraints of the current Internet, set aside concerns about compatibility with existing software, and rebuild the entire network from scratch. Clean-slate approaches have the...
Machine-to-machine (M2M) communication represents an important new class of applications for the future “Internet of Things (IoT)”. The IoT scenario requires scalable connectivity to billions of embedded devices such as sensors, RFID's and machines. Current sensor networking solutions involve the use of gateways for hierarchical access to sensor devices, but this approach leads to specialized M2M...
The 3GPP Long Term Evolution (LTE) is considered as a dominant future cellular wireless technology in terms of performance and user experience. With technological advancement of wireless networks, dependencies and business impact of mobile network services have also been increased phenomenally. It is, therefore, crucial to address issues regarding network infrastructure or service failure. In this...
Mobile and wireless communication has been evolved from the basic model for providing point-to-point (PtP) voice centric services into more complicated service provision technologies with point-to- multipoint (PtM) transmission mode, such as MBMS in 3GPP and BCMCS in 3GPP2. On the other hand, the evolution of mobile and wireless communication has also resulted in a large number of wireless technologies...
Nowadays, a number of processor cores are available, either as soft intellectual property (IP) cores or as hard macros that can be employed in developing new systems on a chip. Developers of applications targeting harsh environments like the atmospheric radiation environment or the space radiation environment may benefit from the computing power of processor cores, provided that suitable techniques...
To support user mobility across different devices, communication session continuity should be enabled at session initiation and during a session. The session continuity can be managed by either a user or dedicated network nodes such as back-to-back user agent (B2BUA) in IP Multimedia Subsystem (IMS) architecture. When network manages the session continuity, user experience is enriched because users...
Increasing demand for mobile data communications and for various applications encourages mobile network operators (MNOs) to deploy new radio access technologies (RATs). The third generation partner project (3GPP) has specified an all-IP-based mobile core network: evolved packet core (EPC) which can can accommodate a 3.9-G RAT (Long Term Evolution [LTE]) as well as conventional RATs, such as UMTS and...
Unified Communication and Collaboration (UCC) system is the converging service of all communications. IMS (IP Multimedia Subsystem) is expected to be a core service for both Internet and mobile phones. Hence, UCC certainly involves with IMS to provide a future service to both world. Presence service is crucial component in UCC system. It provides notifications and presence information of users and...
Over the past three decades, the Internet has evolved from a point to point, open, academic network to an applications and services oriented critical infrastructure. The Internet has become a vital component of society today, from its simple origin as an academic research project. During this transition, numerous applications and usages of the network emerged that cannot be efficiently implemented...
Virtualization, in telecommunication, has been given great interest over the 20 past years. Migrating operating system instances between physical hosts is one of the most important features of this technology. It allows network administrators to resolve serious problem such us hardware failure, lack in server capacity, while facilitates the management and the upgrade of their systems. With the strong...
Wireless networks will certainly run applications with strict QoS requirements and so, micro-mobility protocols such as fast hierarchical mobile IPv6 (FHMIP) are useful tools to accomplish this new feature. The FHMIP is an effective scheme to reduce Mobile IPv6 handover disruption, however it does not support application's QoS requirements. Therefore, in order to provide QoS guarantees for real-time...
The pervasive computing field is almost always addressed from application, middleware, sensing or human computer interaction perspective. Thus, solutions are usually designed at application level or involve developing new hardware. Although current layered network architectures (mainly TCP/IP stack) have enabled internetworking of lots of different devices and services, they are neither well-suited...
User's requirements have become a key factor for any Quality of Service (QoS) management model to succeed. The advent and rise of new broadband services and network architectures (Triple-Play-Services, NGN...) depends on the ability of providers to achieve user's expectations in these scenarios. For that reason, the overall end user's perception (Quality of Experience - QoE) must be audited, on a...
