Hanieh Kashfi proposes μSDN, a low-overhead SDN architecture for low-power IoT networks. μSDN builds on centralization trends in IEEE 802.15.4 protocols and includes additional optimization techniques to reduce overhead. It aims to provide the advantages of SDN such as global knowledge, network reconfiguration and virtualization to low-power networks while maintaining compatibility with IPv6 and interoperability with routing protocols like RPL. The challenges of applying SDN to low-power wireless mesh networks include device hardware restrictions, unreliable links, interference and multi-hop topologies.

2) By relying only on end-point provisioning and automatic provisioning through its link state protocol, it allows "build it once and don't touch it" functionality, greatly reducing time to deploy new services.
3) It improves network robustness through sub-second failover times and eliminating spanning tree protocols.

Fundamentals of 5G Network Slicing
Network slicing is a method of creating multiple unique logical and virtual networks on a common multi-domain infrastructure.
A different approach to view is that network slicing overlays multiple virtual networks on a shared network. Each part of the network can have its own logical topology, security rules and performance characteristics-within the limits imposed by the basic physical network.
Network slicing is a key function of 5G.
5G network slicing is a virtual network architecture that belongs to the same family as Software-defined Networking (SDN) and Network Function Virtualization (NFV).
The benefits of network slicing are:
It can help network operators reduce expenditure (OPEX) and capital expenditure (CAPEX).
It greatly improves the operational efficiency and time to market for delivering 5G network services.
A single network can be used to provide various services according to user needs and various use cases.
Network operators can allocate the proper amount of required resources as per network slice.
It overcomes all the shortcomings of the most popular QoS solution "DiffServ".

Zigbee Based Wireless Sensor Networks for Smart Campus
The document discusses simulations of Zigbee-based wireless sensor networks using different topologies with static and dynamic positioning of the Zigbee coordinator node. The simulations analyzed the effect on throughput and end-to-end delay. Results showed that a tree topology with a mobile coordinator had the highest throughput. A mesh topology, whether with static or dynamic coordinator, produced the lowest end-to-end delay. The document concludes that making the coordinator node mobile generally provides better network performance than a static coordinator configuration.

Lecture 11 Final.pptx
The document provides information on Software Defined Networking (SDN) and Multi-Protocol Label Switching (MPLS). It discusses how SDN separates the control plane from the data plane in traditional networks to make them more programmable. The key components of the SDN architecture are described. MPLS is introduced as a mechanism for traffic engineering by forwarding packets based on labels rather than lookups. Traffic engineering and generalized MPLS which supports wavelength switching are also summarized.
IRJET- Build SDN with Openflow Controller
This document summarizes a research paper on building an SDN network using an OpenFlow controller. It discusses how SDN addresses limitations in traditional network technologies by introducing programmability through the OpenFlow protocol. It proposes a firewall system for SDN networks to identify attacks and report intrusion events. The paper also implements a load balancing rule based on SDN specifications using Dijkstra's algorithm to find multiple equal cost paths, helping to scale the network. It describes how SDN can improve common network management tasks through paradigm deployments in the field.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
