What is auto configuration in WSN?

Auto-configuration in WSN [24] is a general name for proposals characterized by an update or configuring demand. This type of configuration is simply deployed at a sink and then automatically relayed to other nodes in a WSN.

What do you mean by self Organised WSN?

We define a self-organizing system as one where a collection of units coordinate with each other to form a system that adapts to achieve a goal more efficiently. Finally, we explore some of the ways this definition applies to wireless sensor networks.

How is WSN configured?

3.5. First, a WSN defines its own configuration space. Each network defines its parameters and the relationship between them. According to the protocol in [25], the parameters in each WSN are classified as global, which entails network-level parameters, and local, which entails node-level parameters.

What is robustness in WSN?

Robustness is often defined as invariance degree of state, behavior, and function or the adaptation/flexibility degree under interference of perturbations. Robust analysis of wireless sensor networks is intractable and challenging.

What is meant by node capture?

Among various attacks in wireless sensor network, node capture attack is a serious attack through which an intruder can performs various operations on the network and can easily compromise the entire network. Node captures attack s one of the hazardous attack in WSNs.

How do you maximize the lifetime of WSN?

To obtain the maximum lifetime of the WSN, we need to find out the optimal number of nodes n, the distances between each two adjacent nodes d(i − 1, i), and the corresponding transmission level, such that the energy consumption of the energy hole is minimized.

How do you prevent node capture?

SCADD provides a cost-effective solution against the node compromise and capture attacks in WSNs, enhancing the overall WSN security for security-sensitive applications. This protocol consists of two building blocks: node attack detection block and defence advocating measure block.

What is base station in WSN?

The base stations are one or more components of the WSN with much more computational, energy and communication resources. They act as a gateway between sensor nodes and the end user as they typically forward data from the WSN on to a server.

Is the most populer operating system for WSN?

Contiki [18], is a lightweight open source OS written in C for WSN sensor nodes. Contiki is a highly portable OS and it is build around an event-driven kernel. Contiki provides preemptive multitasking that can be used at the individual process level.

How does Cisco NX-OS work in configuration mode?

Configuration files contain the Cisco NX-OS software commands used to configure the features on a Cisco NX-OS device. Commands are parsed (translated and executed) by the Cisco NX-OS software when the system is booted (from the startup-config file) or when you enter commands at the CLI in a configuration mode.

How to start SSH session on Cisco NX-OS?

You can start SSH sessions using IPv4 or IPv6 to connect to remote devices from the Cisco NX-OS device. Obtain the hostname for the remote device and, if needed, the username on the remote device. Enable the SSH server on the remote device.

What does running config mean in Cisco Nexus 9000?

The running configuration (running-config) contains the current changes that you make to the startup-configuration file. The two configuration files can be different. You might want to change the device configuration for a short time period rather than permanently.

How many feature groups can I add to Cisco NX-OS?

For an explanation of the Cisco NX-OS licensing scheme, see the Cisco NX-OS Licensing Guide. User accounts and RBAC have the following configuration guidelines and limitations: You can add up to 256 rules to a user role. You can add up to 64 user-defined feature groups in addition to the default feature group, L3.
