Elawwad, A., M. Ragab, and H. A. El-Halim, "Vacuum Sewerage System in Developing Regions and the Impact on Environmental Management", the 4 th International Conference on Environmental Pollution and Remediation, Prague, Czech Republic, August 13, 2014. Abstract

Leakage in sewerage system can cause groundwater and soil contamination in urban areas, especially in area with a high groundwater table. This is a serious problem in small agricultural villages which rely on ground water as a source for irrigation and drinking purposes. In the developed countries, the recent trend in areas with low population densities is using vacuum sewerage system. Vacuum system could be environmentally safer than conventional gravity system, protecting public health, preventing exfiltration to the ground water, very easily applied in a relatively short time, and can cope with a faster expansion of the urbanized areas. Detailed hydraulic design were held for both gravity sewer and vacuum sewer systems in 28 Egyptian agricultural villages as a case study for developing regions. Different conditions, such as population, areas, and terrain slopes were evaluated. Cost comparisons based on statistical analysis were done to assess the feasibility of using vacuum sewerage in developing regions. Based on this study, from financial point of view, vacuum sewerage system was a good competitor to conventional systems in flat areas and areas with high groundwater table. From the environmental point of view, it is recommended to construct the vacuum sewerage system in such agricultural villages. The local market supplying of the construction equipment especially collection chambers will greatly affect the investment cost. Capacity building and social mobilization will also play a great role in sustainability of this system.

El-Din, A. E., R. A. Ramadan, and M. B. Fayek, "VEGK: Virtual ECC Group Key for Wireless Sensor Networks", the 2nd international conference on Computing, Networking and Communications (ICNC'13) at the technical symposia Communications and Information Security (CIS 2013), San Diego, USA, January, 2013. Abstract

A Wireless Sensor Network (WSN) is a collection of smart sensor nodes cooperated together for achieving the desire of the assigned application. However, these nodes suffer from different limitations including memory available, computational and communicational limitations. Clustering these nodes is considered as one of the main solutions for prolonging the lifetime of the network. At the same time, security is another challenge for WSNs due to the critical information wirelessly transferred through the network. In this paper, we propose a security framework called Virtual ECC Group Key (VEGK) merging Elliptic Curve Cryptography (ECC) with symmetric pairwise keys along with virtual ECC group keys. In addition, we believe that merging the security with clustering will be beneficial to the energy saving in WSN. Based on the analysis of different scenarios, our proposed security framework is proved to protect the network from many attacks.
