A survey on opportunistic routing and channel assignment scheme in cognitive radio ad hoc networks
TL;DR
Different routing methods for cognitive sensor networks are looked at, including drop ratio, which will assist in lowering the cost of living and guarantee that the data can be handled by nodes with a low dropping ratio.
Abstract
In terms of Cognitive Radio (CR) technology, Cognitive Sensor Networks (CSNs) vary substantially from conventional WSNs. Modification of transmitter settings is needed for CSNs based on the interaction with the surrounding environment. However, routing is an essential component, and routing methods differ from those used in other networks. On the spectrum-awareness feature the routing system should be able to comprehend the changing spectrum resources in order to create a connection. A trustworthy forwarding path Packet losses and node connection are severely impacted by spectrum unavailability. The buffer is full. The length of time packets are dropped has an effect on the data delivery rate and network lifespan. In terms of routing, phase, this flaw aims to extend the life of a network. Power dissipation and packet loss are calculated based on the spectrum connections. We’ve looked at different routing methods for cognitive sensor networks, including drop ratio. These techniques will assist in lowering the cost of living. Drop ratio and guarantee that the data can be handled by nodes with a low dropping ratio. As a result, the network's lifespan and energy consumption are reduced. The efficiency of the system will improve.
