Distributed sensor networks are a developing technology that promises to revolutionize our ability to sense environments, natural and social, over unprecedented spatial and temporal scales.
Creating autonomous, collaborative, and robust computation across a large set of small computing devices.
Distributed Networks makes use of current models in the areas of:
- artificial intelligence,
- machine learning,
- control theory,
- decision theory, and
- distributed computing.
It also brings to the forefront current topics of research that connect the form and function of complex networks.
A distributed network is a type of computer network that is spread over different networks and provides a single data communication network, which can be managed jointly or separately by each network.
Besides shared communication within the network, a distributed network often also distributes processing.
Distributed networks are part of a distributed computing architecture in which enterprise IT infrastructure resources are divided over a number of networks, processors and intermediary devices. A distributed network is powered by network management software, which manages and monitors data routing, combining and allocating network bandwidth, access control and other core networking processes.
- When a single database is lost, it does not affect all the data.
- User interaction is done with a local database, which results in higher access speeds, faster reporting and queries.
- Cheaper operation results from taking the advantage of off-peak rates of communications between Satellite and Master databases syncing on scheduled access.
- The Satellite databases come with local changes until the Master database acknowledges that it has upgraded these changes. This results in preventing accidental loss of local data amid transmission.
- A major improvement in Master database performance, since it does not need to deal with the Satellite database changes consistently. With this, you simply move your Satellite transactional load to a manageable schedule leave a lot of time for other operations.
Disadvantages of Distributed Network
- The distributed database architecture is more demanding in the form of design, administration and analysis.
- There are issues in accessing Satellite data from the Master database, which is often done according to the scheduled syncs. Indeed, there is often a manual override where syncing can be made to occur.
- Many complex routines need to be developed to ensure that data synchronization is working perfectly.
- Delays will exist between the satellite and master data footprints, where many reports generated by the satellite database are not current with the data of the master .
Understanding the advantages and disadvantages helps to have a clear idea about our needs and where and how to implement the thing. There are other applications using Distributed network, besides the master or Satellite databases.
