P.1 Contract theory based caching and pricing strategy for content centric networks
Chen Li, Jintian Li, Zhou Su, Qichao Xu (Shanghai University, China)

Content centric networks (CCNs) have emerged to deliver a large amount of contents in the
networks. However, it has become a new challenge to efficiently cache the contents in the CCNs.
Therefore, in this paper, we design a contract theory based content caching scheme to improve
the performance of CCNs. Firstly, a two-layer heterogeneous network model is introduced to
study the interaction between users and content providers. Secondly, based on the contract
theory, the optimal caching and pricing strategy can be obtained under two constraints in CCNs.
Finally, simulation experiments are carried out to prove that our proposal can efficiently improve
the cache performance of CCNs.

P.2 The IEEE 1906.1 standard: Nanocommunications as a new source of data

Nanoscale communications is a new paradigm encompassing all those concerns related to the
exchange of information among devices at the nanometer scale. A network infrastructure
consisting of a huge amount of nano-devices is envisaged to ensure robust, reliable and
coordinated data transmission. This will enable a plethora of forthcoming applications and
services in many different research fields, such as personalized medicine, synthetic biology,
environmental science or industry, which will lead to outstanding and unprecedented advances.
The IEEE P1906.1 standard provides a conceptual and general framework to set the starting point
for future developments in nanoscale communication networks. This paper reviews the latest
IEEE P1906.1 recommendations, observing their main features when applied to the
electromagnetic (EM) nanocommunication area. We contribute by identifying and discussing the
principal shortcomings of the standard, to which further research efforts must be devoted. We
also provide interesting guidelines for focusing the object of future investigations.

P.3 TASIS: Trend Analysis System for International Standards

Recently, text mining has risen as an advanced technology that analyzes meaningful trends and
topics in document collections. Despite its increasing use in various research areas, there have
not been previous studies using document collections of international standards. In this paper,
we propose the Trend Analysis System for International Standards (TASIS), which automatically
performs topic modeling and trend analysis on document collections of the International
Telecommunication Union Telecommunication Standardization Sector (ITU-T)
Recommendations, based on a latent dirichlet allocation (LDA) algorithm. For providing Web
services, the TASIS performs topic modeling by exploiting user-defined parameters, such as the
number of topics and iterations, and the results show a list of the documents that each keyword
in the topic is included in. The TASIS also describes a TreeMap with the size of the extracted
topic as a graphical expression for easier understanding.
