Report of the AD HOC Expert Group meeting on social exclusion, poverty, inequality, crime and violence: Towardsa research agenda for informed public policy for Caribbean SIDS

The Economic Commission for Latin America and the Caribbean (ECLAC), Subregional Headquarters for the Caribbean convened an expert group meeting on Social Exclusion, Poverty, Inequality – Crime and Violence: Towards a Research Agenda for informed Public Policy for Caribbean SIDS on Friday 4 April 2008, at its conference room in Port of Spain. The meeting was attended by 14 experts drawn from, the University of the West Indies (UWI), St. Augustine, Trinidad and Tobago; and Mona Campus, Jamaica; the St. Georges University, Grenada; the Trinidad and Tobago Crime Commission and the Ministry of Social Development, Government of Trinidad and Tobago and representative of Civil Society from Guyana. Experts from the United Nations System included representatives from the United Nations Fund for Women (UNIFEM), Barbados; the United Nations Development Programme (UNDP), Port of Spain and UNDP Barbados/SRO and the Organisation of Eastern Caribbean States (OECS). The list of participants appears as an annex to this report. The purpose of the meeting was to provide a forum in which differing theories and methodologies useful to addressing the issues of social exclusion, poverty, inequality, crime and violence could be explored. It was expected that at the end of the meeting there would be consensus on areas of research which could be pursued over a two to four-year period by the ECLAC Subregional Headquarters for the Caribbean and its partners, which would lead to informed public policy in support of the reduction of the growing violence in Caribbean society.

The Performance of Elliptic Curve Based Group Diffie-Hellman Protocols for Secure Group Communication over Ad Hoc Networks

The security of the two party Diffie-Hellman key exchange protocol is currently based on the discrete logarithm problem (DLP). However, it can also be built upon the elliptic curve discrete logarithm problem (ECDLP). Most proposed secure group communication schemes employ the DLP-based Diffie-Hellman protocol. This paper proposes the ECDLP-based Diffie-Hellman protocols for secure group communication and evaluates their performance on wireless ad hoc networks. The proposed schemes are compared at the same security level with DLP-based group protocols under different channel conditions. Our experiments and analysis show that the Tree-based Group Elliptic Curve Diffie-Hellman (TGECDH) protocol is the best in overall performance for secure group communication among the four schemes discussed in the paper. Low communication overhead, relatively low computation load and short packets are the main reasons for the good performance of the TGECDH protocol.

Una rassegna di protocolli di routing per reti radio cognitive ad hoc

Questa tesi si propone di presentare e classificare per caratteristiche simili i protocolli di routing che ad oggi sono utilizzati nelle Cognitive Radio Ad Hoc Networks. Pertanto dapprima nel Capitolo 1 si introdurranno le radio cognitive con i concetti che sono alla base di questa tecnologia e le principali motivazioni che hanno portato alla loro nascita e poi al loro sviluppo. Nel Capitolo 2 si parlerà delle cognitive networks o meglio delle cognitive radio networks, e delle loro peculiarità. Nel terzo e nel quarto capitolo si affronteranno le CRAHNs e in particolare quali sono le sfide a cui devono far fronte i protocolli di routing che operano su di essa, partendo dall'esaminare quali sono le differenze che distinguono questa tipologia di rete da una classica rete wireless ad hoc con nodi in grado di muoversi nello spazio (una MANET). Infine nell'ultimo capitolo si cercherà di classificare i protocolli in base ad alcune loro caratteristiche, vedendo poi più nel dettaglio alcuni tra i protocolli più usati.
