Most of the efforts to characterize DTN routing are focused on the trade-off between delivery ratio and delay. Buffer occupancy is usually not considered a problem and most of the related work assumes infinite buffers. In the present work, we focus on the drop ratio for message forwarding considering finite buffers. We model message drops with a continuous time Markov chain (CTMC). To the best of...
We propose a quantitative model to evaluate survivability in large-scale Mobile Ad-hoc NETworks (MANETs). We present modeling for survivability regarding various types of faults and connection states for mobile terminals through continuous time Markov chain. We evaluate the survivability of segment-by-segment routing and multipath routing, introduce reliability theory to perform analysis and quantitative...
In this article we propose exact analysis of the data network node using two transmission channels with different bit transmission rates. The inter arrival time of data packets and the transmission times of each channel are generally distributed. Heterogeneous transmission channels often occur in the data network when channels are working in parallel. Research is in progress to develop exact analytical...
