mesh network

[′mesh ‚net‚wərk]
(communications)
A communications network in which each node has at least two links to other nodes.

mesh network

A communications network in which there are at least two pathways to each node. If one of the paths fails, the other is still available.

A "fully meshed" network means that every node has a direct connection to every other node, which is a very elaborate and expensive architecture. Most mesh networks are partially meshed and require traversing intermediate nodes to go from each node to every other. See mesh, wireless mesh network, topology and 802.11s.


Mesh vs. Star Topologies
In a mesh network, there is more than one path to each node. In contrast, a star network relies on the center node to always be up and running.

The IQRF currently has the following main parameters [14]: (i) unlicensed wireless radio technology (supporting frequencies 868 MHz, 916 MHz and 433 MHz); (ii) P2P or MESH topology; (iii) ultra-low-power (sleep mode--hundreds of nA; transmission--based on mode, average hundreds of [mu]A); (iv) low throughput (19.836 kb/s or 19.2 kb/s); (v) byte oriented protocol DPA for services and peripherals control; (vi) low to medium range (considering small antennas--tens of meters in buildings, hundreds of meters in open space); (vii) security (nodes are bound to the network via password, network encryption via AES-128 with self-distribution of the keys, optional user encryption via AES-128, message checksum CRC-16, and block checksums).
7 is the experiment results taken under a mesh topology of 20 switches and varying out degrees.
The chief drawback of the mesh topology is expense, because of the large number of cables and connections required.
The mesh topology portion of the RFI is interesting, as the assumption might be that military engagements overseas would be used to create temporary mesh networks spanning large portions of the battlefield where no compatible cellular technologies exist.
It consists of a series of genes where each gene corresponds to a tile in the mesh topology. For M x N mesh topology, the length of a chromosome is MxN genes.
Secondly, mesh topology with multihop keeps linking information between sensor nodes and is connected with other nodes.
- an adaptive Smart Mesh topology system that self-organizes, self-optimizes and self-heals to maximize system-level resilience and network performance without manual antenna aiming and topology tuning.
Presenting current research by computer scientists at institutions worldwide, the proceedings features such topics as adaptive cache memories for SMT processors, simulation of high-performance memory allocators, designing efficient source routing for mesh topology network on chip platforms, and design of trace-based split array caches for embedded applications.
At the core of the University's wired network is 10 Gigabit Ethernet, in mesh topology, with around 450 switched distributed over 180 wiring closers with single or dual 1 Gigabit Ethernet links.
The mesh topology (e.g., IEEE 802.15.4) provides reliability.
High-capacity wireless throughput is sustained while aggregating hundreds of video streams across the mesh topology. The business case improves most dramatically in large multisite deployments encompassing many buildings in campuses, business parks, even entire metro areas.
