We derive a model of congestion control where the trade-off between utility and path diversity can be investigated. In a network where there can be multiple routes between locations, each source s is assigned a route according to an allocation scheme where the degree of randomness and therefore path diversity is controlled by hs, the entropy of the distribution defined by the allocation. Model ...

Identifying influential spreaders in complex networks is a crucial problem which relates to wide applications. Many methods based on the global information such as k-shell and PageRank have been applied to rank spreaders. However, most of related previous works overwhelmingly focus on the number of paths for propagation, while whether the paths are diverse enough is usually overlooked. Generall...

Path diversity works by setting up multiple parallel connections between the end points using the topological path redundancy of the network. In this paper, Forward Error Correction (FEC) is applied across multiple independent paths to enhance the endto-end reliability. Internet paths are modeled as erasure Gilbert-Elliot channels [1], [2]. First, it is shown that over any erasure channel, Maxi...

Wireless local area networks, such as 802.11b, are becoming widespread as they provide simple wireless connectivity and data delivery. This paper examines low-latency (conversational) video communication over 802.11b networks. The challenges to enable low-latency video include overcoming the highly variable delays, losses, and bandwidth of 802.11b wireless networks. To overcome these challenges...

The increase in the bandwidth of wireless channels and the computing power of mobile devices increase the interest in video communications over wireless networks. However, the high error rate and the rapidly changing quality of the radio channels can be devastating for the transport of compressed video. In motion compensated coding, errors due to packet losses are propagated from reference fram...

In this paper, we propose an effective path virtualization system using Fountain code that provides the highest possible data rate with satisfactory delay and block loss rate constraints to enhance video quality. Basically, Fountain code and video codec H. 264 are tightly coupled to efficiently use the path diversity over existing heterogeneous wireless networks. Finally, the proposed system is...

This paper proposes a framework calledVirtualMulti-Homing (VMH) to achieve loose source-based path selection and improve interdomain path diversity. VMH is based on the concept ofVirtual Peering and Multi-Homing Overlay to set up exible inter-domain relationships. By interacting with BGP whenever possible, VMH can achieve scalable inter-domain route discovery without introducing duplicate work....

This paper presents a novel evolutionary G–continuous (continuous-differentiable curvature) path planner for nonholonomic wheeled mobile robots. The evolutionary path planner generates intermediate configurations connected via η-splines that yields a collision-free G–continuous path, which each point on the path has a closed-form expression. The path planner is implemented as architecture of is...

Multiple description (MD) coders provide important error resilience properties. Specifically, MD coders are designed to provide good performance when the loss is limited to a single description, but it is not known in advance which description. In [1], we combined MD video coding with a path diversity transmission system for packet networks such as the Internet, where different descriptions are...
