Module Aims
The aim of the course is to introduce the basics

of mobile Web service development, to discuss Web service technologies and how they are building into and are integrated in distributed mobile and Web applications.
The second aim is introducing the mechanisms for representing, manipulating and querying structured data (XML) and semantic data (RDF/s, OWL), it also includes data mining techniques and the concept of connected services.
Related toolkits and applications and their use will be discussed.

Communication Networks
There are large volumes of data,
Functionalities to process data,

and capabilities to interact with entities in the physical and virtual worlds. (services)
Communication Network:
AT&T network as an example1
Currently carries 18.7 Petabytes of data traffic on an average business day (PB = 10 ^15 bytes),
Nearly 5 Billion calls per day.
Cisco Prediction2:
295 Petabyte per month (mobile-to-mobile communications) by 2015,
By 2020 this will be 1000 more compared with 2010.
Challenges include volume, volatility, complexity, reliability, privacy, security, and processing.

Networks of the Future - Challenges
Large-scale networks, huge volumes of data,

dynamic and sometimes unreliable resources;
more dynamic and transient resources and subject to quality changes
scalability of the solutions
heterogeneity and interoperability issues - more devices are contented, more diversity
express-ability and extensibility of semantics and metadata
more autonomous processes (integration, aggregation, filtering, ...) are required
management of the resources
scarcity of: bandwidth, power, energy, addressing and naming schemes, and operation cost.

… but also Dynamicity and Quality:
But it is not just about

volume

How can we efficiently deal with:
Large amounts of (heterogeneous/distributed) service?
Both static and dynamic data/service?
In a re-usable, modular, flexible way?
Integrate different types of services
Provide quality-aware and context-aware solutions

Services
We need mobile and pervasive services that are:
Flexible
Interoperable
Reliable
Discoverable
Support different QoS requirements
…
To

support future data/functionality requirements information communication networks

Слайд 15

Services on the Web
Web Services provide data and services to other

applications.
Thee applications access Web Services via standard Web Formats (HTTP, HTML, XML, and SOAP), with no need to know how the Web Service itself is implemented.
Web services provide a standard means of interoperating between different software applications, running on a variety of platforms and/or frameworks.

The role of metadata
semantic tagging
(machine-interpretable) data annotation and resource descriptions
re-usable descriptions

and vocabularies
resource description frameworks
structured data, structured query
