Delay Tolerant Network protocols for an Expanding Network on a Railway
.
Tikhonov E., Schneps-Schneppe D., Namiot D.
The paper presents the analysis of the Delay Tolerant Network (DTN) methods in an expanding communication network on a railway line. Trains act as moving objects that send and receive messages or collected telemetry data to or from an external network. They can exchange the data with each other, delegating delivery. The paper compares various DTN protocols’ ability to reduce the delay of data delivery and the additional buffer load needed. An analysis is based on the real European railway line example (map and train schedule), with various loads and different coverage of a mobile network. The effectiveness of DTN during migration to networks of a higher data rate (for example, with 5G capabilities) is discussed.

Emerging wireless systems target to provide multi-Gbps data rates for each user, which can be achieved by utilizing ultra-wide channels available at mmWave, terahertz, and lightwave frequencies. In contrast to the traditional spectrum below 6 GHz, these high-frequency bands raise many issues, complicating their usage. For example, because of high signal attenuation and blockage by ...

The paper considers a network of resource loss systems (ReLS) with random resource requirements and two types of nodes. Customers initially arrive to the first type of nodes, where they receive service for exponentially distributed time. The service of customers can be interrupted. In this case, they are rerouted to the second type of nodes, ...
