A Steiner Tree Based Approach For The Efficient Support Of Multipoint Communications In A Multi-Domain Context
2017Co-Authors: Lunde Chen, Slim Abdellatif, Thierry Gayraud, Pascal BerthouAbstract:This work proposes an approach based on Steiner trees to efficiently support multipoint communications in a multi-domain context, where each domain exposes a synthetic and Aggregated View of its network. The approach that we propose is based on two pillars: The adoption of a topology aggregation of each domain's network as a Steiner tree and the use of a shortest path heuristic for the calculation of these Aggregated networks as well as the global Steiner tree. An extensive experimental study on random and real network topologies shows the gains made by our approach in terms of both accuracy and computational complexity.

toward a dis Aggregated View of crop livestock integration in western africa
Land Use Policy, 2003Co-Authors: James SumbergAbstract:Abstract This paper presents a framework for conceptualising crop–livestock integration along four dimensions: space, time, management and ownership. The framework highlights the fact that benefits from crop–livestock interactions can be gained by integration along one, some or all of these dimensions, although the space dimension is particularly important. The implications of four factors—the ‘sustainability imperative’; the human, livestock density relationship; the ‘livestock revolution’; and large-scale tsetse clearance—are then explored in relation to the claim that greater crop–livestock integration should be the basis of agricultural development in West Africa. The conclusion of this analysis is that greater crop–livestock integration is likely to be of interest primarily in ‘middle’ countryside areas with relatively good natural resources.
