The low cost, simplicity, and ease of use of paper microfluidic devices have made them valuable medical diagnostics for applications from pregnancy testing to COVID-19 screening. Meanwhile, the increasing complexity of paper-based microfluidic devices is driving the need to produce new tools and methodologies that enable more robust biological diag...
Inspired by recent innovations in the retail industry, we study an on-demand personal shopper service that lets customers shop online for products from brick and mortar stores. A fleet of personal shoppers fulfills customer orders, performing both shopping at the stores and delivery to the customers. The operation of such a service requires to dyna...

Payment Channel Networks have been developed to deal with the scalability issue in blockchain technologies. Using them, two parties can make multiple payments between themselves relatively fast. However, usually the channels have too small capacities, unable to handle a big payment. Allowing to split a payment into smaller payments and forwarding t...
Popular cryptocurrencies lack scalability. Payment Channel Networks (PCN's) allow a large increase in transaction throughput. However, transaction failures are frequent when transactions are routed through multiple intermediaries. A previously introduced protocol, Interdimensional SpeedyMurmurs, increased the success ratio of transactions in PCN's ...
The Lightning Network aims to solve Bitcoin's scalability problem by providing a way to transact with minimal use of the blockchain. Instead, payments are routed over payment channel networks. This routing is done by LN clients, which use cost functions to compute the optimal transaction path. With the use of onion routing, LN tries to hide the ide...
In network optimization problems, from traffic engineering to network monitoring, the routing model is typically considered as something given and frozen. This paper is motivated by the fundamental question how the ability to change and optimize the routing model itself influences the efficiency at which communication networks can be operated. To t...

In this paper we consider opportunistic routing in multiple-input–multiple-output (MIMO) random wireless ad-hoc networks (WANETs). Our analysis uses a proper model of the physical layer together with an abstraction of the higher communication layers. We assume that the nodes are distributed according to a Poisson point process and consider a routin...

Among the many factors causing damage to lifelines, there are active faults along the pipeline route that can cause fracture and breakdown of the pipeline if it is justified. Thus, during pipeline route study phase, detailed geological work on the route should be undertaken and fault paths identified. It is, therefore, essential to study the struct...
The Fog Computing paradigm provides a seamless bridge between the Cloud and the Edge computing architectures. Depending on the their QoS requirements, tasks can be processed in either the Edge or the Cloud or migrated from one to the other. For the benefits of this flexible architecture to be seen, task allocation algorithms should be able to adapt...
