Coordination in Service Value Networks - A Mechanism Design Approach
The fundamental paradigm shift from traditional value chains to agile service value networks (SVN) implies new economic and organizational challenges. This work provides an auction-based coordination mechanism that enables the allocation and pricing of service compositions in SVNs. The mechanism is multidimensional incentive compatible and implements an ex-post service level enforcement. Further extensions of the mechanism are evaluated following analytical and numerical research methods
The doctoral research abstracts. Vol:11 2017 / Institute of Graduate Studies, UiTM
Foreword:
Congratulation to IGS on the continuous effort to publish the 11th issue of the Doctoral Research
Abstracts which highlights the research in various disciplines from science and technology, business
and administration to social science and humanities. This research abstract issue features the abstracts
from 91 PhD doctorates who will receive their scrolls in this 86th UiTM momentous convocation
ceremony. This is a special year for the Institute of Graduate Studies where we are celebrating our
20th anniversary. The 20th anniversary is celebrated with pride with an increase in the number of PhD
graduates.
In this 86th convocation, the number of PhD graduates has increased by 30%
compared to the previous convocation. Each research produces an innovation
and this year, 91 research innovations have been successfully recognized to have
made contributions to the body of knowledge. This is in line with this year UiTM
theme that is “Inovasi Melonjak Persaingan Global (Innovation Soars Global
Competition)”.
Embarking on PhD research may not have been an easy decision for many of
you. It often comes at a point in life when the decision to further one’s studies
is challenged by the comfort of status quo. I would like it to be known that you
have most certainly done UiTM proud by journeying through the scholarly
world with its endless challenges and obstacles, and by persevering right
till the very end.
Again, congratulations to all PhD graduates. As you leave the university
as alumni we hope a new relationship will be fostered between you
and UiTM to ensure UiTM soars to greater heights. I wish you all the
best in your future endeavor. Keep UiTM close to your heart and be
our ambassadors wherever you go. / Prof Emeritus Dato’ Dr Hassan Said

Smart PIN: performance and cost-oriented context-aware personal information network
The next generation of networks will involve interconnection of heterogeneous individual
networks such as WPAN, WLAN, WMAN and Cellular network, adopting the IP as common infrastructural protocol and providing virtually always-connected network. Furthermore,
there are many devices which enable easy acquisition and storage of information as pictures, movies, emails, etc. Therefore, the information overload and divergent content’s
characteristics make it difficult for users to handle their data in manual way. Consequently, there is a need for personalised automatic services which would enable data exchange across heterogeneous network and devices. To support these personalised services, user centric approaches
for data delivery across the heterogeneous network are also required.
In this context, this thesis proposes Smart PIN - a novel performance and cost-oriented context-aware Personal Information Network. Smart PIN's architecture is detailed including its network, service and management components. Within the service component, two novel schemes for efficient delivery of context and content data are proposed:
Multimedia Data Replication Scheme (MDRS) and Quality-oriented Algorithm for Multiple-source Multimedia Delivery (QAMMD).
MDRS supports efficient data accessibility among distributed devices using data replication which is based on a utility function and a minimum data set. QAMMD employs a buffer underflow avoidance scheme for streaming, which achieves high multimedia quality without content adaptation to network conditions. Simulation models for MDRS and
QAMMD were built which are based on various heterogeneous network scenarios. Additionally a multiple-source streaming based on QAMMS was implemented as a prototype and tested in an emulated network environment. Comparative tests show that MDRS and QAMMD perform significantly better than other approaches
Internet of robotic things : converging sensing/actuating, hypoconnectivity, artificial intelligence and IoT Platforms
The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications
