Why multi hop wireless communication is required for WSN?

Why multi hop wireless communication is required for WSN?

Wireless Sensor Networks (WSN) can be made more energy efficient by adopting multihop communication rather than single hop communication. Relaying heavy data traffic through nearby nodes of sink arises energy holes which is very crucial to prolong network lifetime.

What is one hop and multi hop?

Single Hop vs Multi Hop In Internet When packet travels from source to destination using single networking device, it is known as single hop system. • When packet travels from source to destination using more than one networking devices, it is known as multi hop system.

What is multimedia wireless sensor network?

As a result, Wireless Multimedia Sensor Network (WMSN) [6] is a network of wirelessly interconnected sensor nodes equipped with multimedia devices, such as cameras and microphones, and capable to retrieve video and audio streams, still images, as well as scalar sensor data.

What is hop in wireless communication?

1) In a packet-switching network, a hop is the trip a data packet takes from one router or intermediate point to another in the network. On the Internet (or a network that uses TCP/IP), the number of hops a packet has taken toward its destination (called the “hop count”) is kept in the packet header.

What is single hop communication in WSN?

Single-hop network: A network is said to be single- hop if the cluster-head is one hop away from the sensor node in a cluster.

What is multi-hop ad hoc network?

Multi-hop, or ad hoc, wireless networks use two or more wireless hops to convey information from a source to a destination. There are two distinct applications of multi-hop communication, with common features, but different applications.

What is base station in WSN?

The base station is at the upper level of the hierarchical WSN. It provides the communication link between the sensor network and the end-user. It contains the antennas and other equipment needed to allow wireless communications devices to connect with the network.

What are multimedia nodes?

A node usually represents a single concept or idea. It can contain text, graphics, animation, audio, video, images or programs. It can be typed (such as detail, proposition, collection, summary, observation, issue) thereby carrying semantic information [Rao & Turoff, 1990]. Nodes are connected to other nodes by links.

What is multi-hop cellular network?

Multi-hop cellular network (MCN) is an architecture proposed by Lin and Hsu (see INFOCOM 2000. IEEE, 2000) for wireless communication & MCNs combine the benefits of having a fixed infrastructure of base stations and the flexibility of ad-hoc networks.

What is multi-hop reasoning?

Multi-hop reasoning is an effective approach for query answering (QA) over incomplete knowledge graphs (KGs). The problem can be formulated in a reinforcement learning (RL) setup, where a policy-based agent sequentially extends its inference path until it reaches a target.
