In opportunistic networks, messages are delivered based on a store-forward-carry paradigm. Network topology varies with time and dynamism of the links between nodes has a primary effect on the message delay, one of the network performance indicators. To get a precise estimation of the network latency with less complexity, a rigorous framework modeling the information propagation process is developed...
A new, deadlock-free, fully adaptive routing algorithm is proposed for worm hole-switched 3-dimensional tori with only two virtual channels. The deadlock avoidance technique is presented based on a new virtual network partitioning scheme. Unlike the previous virtual network partitioning schemes, the new method allows all virtual networks to share some common virtual channels. A new virtual channel...
A new deadlock-free fully adaptive routing algorithm is proposed for 2-dimensional tori with only two virtual channels. The deadlock avoidance technique is presented based on a new virtual network partitioning scheme. Unlike the previous virtual network partitioning schemes, the new method allows all virtual networks to share some common virtual channels. Two virtual channels should be the lower bound...
This paper presents the design, implementation and evaluation of a solution for dynamic redirection of traffic flows for multihomed mobile networks. The solution was developed for a mobile user that disposes of a Personal Area Network (PAN) with a Personal Mobile Router (PMR), in order to achieve Always Best Connected (ABC) service by distributing flows belonging to different applications among the...
