Studying about wireless networks (WN), the expressions 'collaborative WN' and 'cooperative WN' are common. However, It is no clear for me to understand the difference. Some authors use them as synonymous, others as different concepts. Then, how to understand them?, i.e.
- What is the difference between Collaborative WN and Cooperative WN?,
- How do you understand these concepts?
- How to complete the following statements
- A wireless device collaborates with a wireless network when __________.
- A wireless device cooperates with a wireless network when __________.
I am very interested in your opinion... Thanks
Wireless sensor networks (WSNs) architectures involve many power-limited sensor nodes to enable a large class of applications for monitoring. In most cases, harsh environment and energy constraints represent issues that impede or slow down the deployment of such networks. However, based on collaboration (infrastructure-based and P2P-based), WSNs can organize efficiently or even self-organize, prolong system lifetime, handle dynamics, and detect and correct errors, all with the final goal of eventually executing reliably the user application. In spite of the increasing demand for all kinds of sensing services and applications, we are still lacking a clear understanding of collaborative techniques, as well as best practices, to design collaborative architectures, protocols, algorithms, sensing, query, data processing, localization, and tracking for WSNs. In particular, dynamic spectrum access, machine to machine, cognitive radio, ultrawideband, and cooperative communications, among other techniques like radar identification techniques, will have a profound impact on our ability to flexibly and predictably design collaboration in WSNs.
On the other hand, Cooperative communication has been shown as an effective way of exploiting spatial diversity to improve the quality of wireless links. The key feature of cooperative transmission is to encourage single-antenna devices to
share their antennas cooperatively such that a virtual and distributed antenna array can be constructed and, as a result, reception reliability can be improved and power consumption can be reduced significantly.
Hope this answer will help you to understand cooperative and collaborative terms.
Cooperative and collaborative networks are similar in function generally. However,Collaborative networks may share resources while Cooperative networks are complementary but not necessarily sharing their resources.
They are similar to each other but the name (Cooperative Network) is mostly used to express the collaborative architecture of the wireless networks.
