Distributed Transmission Resource Allocation for Network Collision Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer networks, as the number of devices increases, the likelihood of network overload and access collisions rises, leading to slowed performance and increased transmission latencies, particularly when devices access the network in an unscheduled manner, which also decreases the power efficiency of low-power devices.
Innovation Solution
Implementing a distributed transmission resource allocation protocol that allows neighboring network nodes to negotiate and reserve network resources independently, reducing the need for central node management and minimizing collisions by selecting alternative transmission resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If greater numbers of devices are networked together using a common medium, then network connectivity and information distribution capability are improved, but the probabilities for overloading the medium bandwidth and generating access collisions are increased
Solution Approach 1:
The patent segments the network medium access into distinct time slots and frequency channels, dividing the common medium into multiple transmission resources. This segmentation allows multiple devices to share the medium simultaneously without collision by assigning different time-frequency resources to different transmissions.
Solution Approach 2:
The patent implements preliminary resource reservation where devices negotiate and reserve transmission resources before actual data transmission. This preliminary action prevents bandwidth overload by ensuring that resource allocation is decided in advance, avoiding contention during actual transmission.
2Ease of operation
If devices access the network in an unscheduled manner, then ease of operation is improved, but access collisions increase and performance slows down
Solution Approach 1:
The patent enables devices to autonomously negotiate and allocate transmission resources through distributed communication protocols. Each device can independently select and reserve resources without central coordination, maintaining ease of operation while preventing collisions through self-organized resource management.
Solution Approach 2:
The patent incorporates feedback mechanisms where devices monitor medium usage and adjust their resource selection based on observed transmissions. This feedback allows devices to adapt their access patterns dynamically, maintaining simple operation while improving overall network performance by avoiding collisions.
3Use of energy by moving object
If unaddressed transmissions are sent to reduce power consumption, then energy efficiency is improved, but collision probability increases
Solution Approach 1:
The patent uses preliminary resource reservation where devices secure transmission resources in advance through negotiation. This allows devices to transmit at predetermined times and frequencies without needing to continuously monitor the medium, reducing power consumption while ensuring collision-free transmission through pre-coordinated resource allocation.

AI summary
A selected network element is arranged for distributed transmission resource allocation conflict reduction. The selected network element receives a transmission from one of a first other network element and a second other network element and identifies at least one transmission resource indicated by the received transmission as being reserved by the first other network element and the second other network element. The selected network element stores an indication of each of the at least one identified transmission resource. In response to reading the stored indications, the selected network element selects a different transmission resource that is different from the transmission resource indicated by the stored indications. The selected network element transmits a transmission from the selected network element using the selected different transmission resource.
