Optimizing Key Distribution in Peer to Peer Network Using B-Trees

Peer to peer network architecture introduces many desired features including self-scalability that led to achieving higher efficiency rate than the traditional server-client architecture. This was contributed to the highly distributed architecture of peer to peer network. Meanwhile, the lack of a centralized control unit in peer to peer network introduces some challenge. One of these challenges is key distribution and management in such an architecture. This research will explore the possibility of developing a novel scheme for distributing and managing keys in peer to peer network architecture efficiently

Modeling and analyzing the agroecological performance of farms with ECOPATH

Intensive and integrated resource management, where field crops, vegetables, trees, livestock and fish production are combined through efficient reuse of wastes, residues, by-products and external inputs, offers a potential avenue towards a productive and ecologically balanced agriculture. The ECOPATH model software provides important insights into the structure and function of global aquatic ecosystems. The application of the same concept and approach to terrestrial-based culture systems exemplifies a tool which has the potential to improve communication and productivity within research while addressing the issue of sustainable natural resources management.Farming systems, Agricultural ecology, Resource management, Mathemathical models, Monitoring, Modelling
