Cost-Effective Resource Allocation of Overlay Routing Relay Nodes

Cost-Effective Resource Allocation of Overlay Routing Relay  Nodes Overlay routing is a very attractive scheme that allows improving certain properties of the routing (such as delay or TCP throughput) without the need to change the standards of the current underlying routing. However, deploying overlay routing requires the placement and maintenance of overlay infrastructure. This gives rise to the following optimization problem: Find a minimal set […]


Cooperative Caching for Efficient Data Access in Disruption Tolerant Networks

Cooperative Caching for Efficient Data Access in Disruption  Tolerant Networks Disruption tolerant networks (DTNs) are characterized by low node density, unpredictable node mobility, and lack of global network information. Most of current research efforts in DTNs focus on dataforwarding, but only limited work has been done on providing efficient data access to mobile users. In this paper, we propose a novel approach to support cooperative caching in DTNs, […]
