Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in data throughput and reliable data delivery due to limitations in media access protocols, particularly in ad hoc networks where channel assignments are not always necessary for data transmission, leading to inefficiencies in energy consumption and adaptability to varying environments.
Innovation Solution
The implementation of an adaptive connectionless scheduling protocol (CSP) that uses pseudorandom scheduling to determine wireless media locations without pre-assigning channels, allowing nodes to transmit data directly based on pseudorandom sequences, thereby optimizing data rate and latency across a wide range of traffic scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional media access protocols are used with pre-assigned channels, then channel organization is simplified, but data throughput and energy efficiency deteriorate due to unnecessary channel assignment overhead and inability to adapt to varying traffic scenarios
Solution Approach 1:
The patent extracts and removes the channel assignment mechanism from the media access protocol, allowing nodes to transmit data directly using pseudorandom sequences without requiring pre-assigned channels. This eliminates the overhead and complexity associated with channel management while maintaining organized communication through the use of unique pseudorandom codes for each node.
Solution Approach 2:
The patent introduces dynamic adaptability by allowing nodes to adjust their transmission parameters and pseudorandom sequences based on varying traffic scenarios and network conditions. This enables the system to optimize performance for different traffic types and loads without requiring reconfiguration of channel assignments.
2Use of energy by moving object
If pre-assigned channel protocols are used, then channel organization is maintained, but energy consumption increases due to waiting for channel assignments and protocol overhead
Solution Approach 1:
The patent applies preliminary action by pre-generating and storing pseudorandom sequences for each node before transmission begins. Nodes have their transmission codes ready in advance, eliminating the need to wait for channel assignments during data transmission. This preliminary preparation of pseudorandom codes allows immediate transmission when data needs to be sent.
Solution Approach 2:
Each node independently generates and manages its own pseudorandom transmission sequences without requiring centralized channel assignment or coordination. This self-service approach allows nodes to autonomously determine their transmission parameters and timing, eliminating waiting time for channel assignments and reducing protocol overhead.
3Use of energy by moving object
If ad hoc networks transmit data without channel assignments, then energy efficiency improves, but data delivery reliability deteriorates due to potential collisions and lack of coordination
Solution Approach 1:
The patent applies local quality by assigning unique pseudorandom sequences to individual nodes or node pairs, creating locally optimized transmission characteristics for each communication link. This allows each node to transmit with its own customized code, reducing collisions through code orthogonality while maintaining energy efficiency by avoiding centralized channel assignment.
Solution Approach 2:
The patent implements feedback mechanisms where nodes monitor transmission success and adjust their pseudorandom sequences or transmission parameters based on detected collisions or interference. This adaptive feedback allows the system to maintain high reliability by dynamically resolving conflicts while preserving energy efficiency through the continued use of connectionless transmission.
