Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cell-based mobile ad-hoc networks, the transmission of long ID strings for resource allocation messages is problematic in adversarial or challenging environments, such as during lightning storms, necessitating efficient and robust communication protocols for node-joining and node-to-node communication.
Innovation Solution
A method and system that involve monitoring pilot signals, selecting and optimizing aliases with lower bit counts, and incorporating these aliases into resource allocation messages to ensure efficient and unique identification of nodes within cells, allowing nodes to participate in multiple cells with different aliases, thereby reducing message length and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If long ID strings are transmitted in resource allocation messages, then node identification accuracy is improved, but transmission reliability deteriorates in adversarial environments
Solution Approach 1:
The patent segments the node identification into two parts: a long permanent ID string stored locally at each node, and a short alias transmitted in resource allocation messages. This segmentation allows accurate node identification through the permanent ID while improving transmission reliability by using the shorter alias in messages, thus resolving the contradiction between identification accuracy and transmission reliability in adversarial environments.
Solution Approach 2:
The patent introduces an alias as an intermediary element that substitutes for the long permanent ID string in resource allocation messages. The alias acts as a mediator that maintains the connection between the transmitting node and receiving node without requiring transmission of the full long ID, thereby preserving identification accuracy while enhancing transmission reliability in challenging environments.
2Loss of information
If long ID strings are transmitted in resource allocation messages, then node identification completeness is improved, but transmission efficiency deteriorates
Solution Approach 1:
The patent divides node identification information into a permanent long ID string stored locally and a short alias transmitted in messages. This segmentation enables complete node identification to be maintained through local storage while significantly improving transmission efficiency by sending only the short alias in resource allocation messages, thus resolving the contradiction between identification completeness and transmission efficiency.
Solution Approach 2:
The patent extracts the essential identifying feature (the alias) from the complete node identification (long ID string) and uses only this extracted portion for transmission in resource allocation messages. This extraction maintains sufficient node identification capability while dramatically reducing message length and improving transmission efficiency.
3Productivity
If short aliases are used in resource allocation messages, then transmission efficiency is improved, but node identification uniqueness may deteriorate
Solution Approach 1:
The patent segments identification into a short alias for transmission and a long permanent ID for unique identification. The short alias improves transmission efficiency in resource allocation messages, while the long permanent ID stored locally at each node ensures unique node identification is maintained, thus resolving the contradiction between transmission efficiency and identification uniqueness.
Solution Approach 2:
The alias serves as an intermediary that enables efficient transmission while the permanent ID ensures unique identification. The system maintains the intermediary alias for message transmission efficiency while relying on the permanent ID stored locally to guarantee node identification uniqueness, resolving the apparent conflict between these two requirements.
Data Source
AI summary
A communication system and method for joining a first cell in a network is disclosed. The system includes a plurality of nodes with one node configured as a base station and one or more nodes of the plurality of nodes configured as user equipment. Aliased resource allocation messages are used to send scheduling information to the user equipment, for which proper aliases must be determined. To ensure that proper aliasing is utilized, the base station and user equipment determine that the alias is unique. The base station may also recommend an alias with a smaller bit size. The communication system may also include a second cell that shares user equipment with the first cell, with each shared user equipment having a cell-specific alias.
