Allocation of Repetition Redundancy in LoRa
CoRR, 2019 We consider a multipoint-to-point network in which sensors periodically send measurements to a gateway. The system uses Long Range (LoRa) communications in a frequency band with duty-cycle limits. Our aim is to enhance the reliability of the measurement transmissions.

Active redundancy allocation in systems [PDF]
, 2002 An effective way of improving the reliability of a system is the allocation of active redundancy. Let $X_{1}$, $X_{2}$ be independent lifetimes of the components $C_{1}$ and $C_{2}$, respectively, which form a series system.

System reliability-redundancy allocation by evolutionary computation [PDF]
2017 2nd International Conference on System Reliability and Safety (ICSRS), 2017 This paper addresses the system reliability-redundancy allocation problem by resorting to three evolutionary computation methods, namely genetic algorithm, cuckoo optimization algorithm with penalty function, and penalty guided stochastic fractal search. The numerical results are compared in order to highlight the differences in the solution methods.

CoShare: An Efficient Approach for Redundancy Allocation in NFV [PDF]
IEEE/ACM Transactions on Networking, 2022 An appealing feature of Network Function Virtualization (NFV) is that in an NFV-based network, a network function (NF) instance may be placed at any node. On the one hand this offers great flexibility in allocation of redundant instances, but on the other hand it makes the allocation a unique and difficult challenge.

Redundancy-Guaranteed and Receiving-Constrained Disaster Backup in Cloud Data Center Network
IEEE Access, 2018 For disaster backup in cloud data center network, existing researches have not jointly considered sufficient data redundancy and limited receiving capacity, likely to result in underutilization of network transmission capability, unfair distribution of ...

A two-phase linear programming approach for redundancy allocation problems [PDF]
Yugoslav Journal of Operations Research, 2002 Provision of redundant components in parallel is an efficient way to increase the system reliability, however, the weight, volume and cost of the system will increase simultaneously.
