Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networks incorporating both single-radio and multi-radio nodes face inefficiencies in bandwidth utilization and require complex synchronization techniques, leading to either suboptimal bandwidth use or time-consuming synchronization processes.
Innovation Solution
Implementing a method where multi-radio nodes keep one radio tuned to the control channel and all nodes release control and data channels at predetermined times, allowing single-radio nodes to tune to the control channel for synchronization and enabling efficient channel access, thereby enhancing bandwidth utilization and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional synchronization techniques are used in networks with both single-radio and multi-radio nodes, then all nodes can access channels, but bandwidth utilization decreases and synchronization becomes time-consuming
Solution Approach 1:
The patent segments the network into two distinct node types with specialized functions: single-radio nodes that release channels at predetermined times and multi-radio nodes that maintain continuous control channel access. This segmentation allows each node type to operate optimally without requiring complex synchronization between all nodes, thereby increasing bandwidth utilization while reducing synchronization overhead.
Solution Approach 2:
Single-radio nodes periodically release control and data channels at predetermined times, creating a rhythmic pattern of channel access. This periodic action allows multi-radio nodes to continuously occupy channels for data transmission while single-radio nodes periodically gain access for control channel communication, eliminating the need for continuous synchronization and improving overall bandwidth efficiency.
2Productivity
If multi-radio nodes continuously occupy data channels, then bandwidth utilization increases, but single-radio nodes cannot access channels without complex synchronization
Solution Approach 1:
The patent divides network functionality between two node types: multi-radio nodes handle continuous data transmission on data channels, while single-radio nodes handle periodic control channel access. This functional segmentation eliminates the need for complex inter-node synchronization, as each type operates independently according to its designated role.
Solution Approach 2:
The control channel serves as an intermediary resource that single-radio nodes access periodically at predetermined times. This intermediary approach allows single-radio nodes to communicate control information without requiring simultaneous access to data channels, thereby maintaining simple operation while enabling multi-radio nodes to continuously utilize data channels for high-speed data transmission.
3Reliability
If single-radio nodes access control channel continuously, then synchronization is maintained, but bandwidth utilization decreases due to idle time
Solution Approach 1:
Single-radio nodes access the control channel periodically at predetermined times rather than continuously. This periodic access maintains sufficient synchronization reliability for control functions while allowing data channels to remain continuously occupied by multi-radio nodes, thereby maximizing bandwidth utilization without compromising synchronization needs.
Solution Approach 2:
The patent ensures continuous useful action on data channels by allowing multi-radio nodes to occupy them without interruption. Meanwhile, control channel access by single-radio nodes is scheduled at predetermined times that do not interfere with data channel continuity, maintaining both synchronization reliability and maximum bandwidth utilization.

AI summary
A method, apparatus and computer program product for using a single-radio node and a multi-radio node in a wireless network having a control channel and at least one data channel is presented. One radio of the multi-radio node is kept tuned to the control channel. The single-radio node and the multi-radio node release the control channel at a predetermined time. Further, the data channels used by the single-radio nodes are released at the predetermined time. In such a manner single-radio and multi-radio nodes can co-exist harmoniously in wireless networks with increased bandwidth utilization and efficiency.
