Clustered Network Inter-Cluster Signaling Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ad hoc wireless communication networks, cluster leaders face difficulties in communicating with neighboring cluster leaders due to the need for coordination and efficient access to radio resources, which is topology-dependent, making inter-cluster signaling inefficient and less frequent.
Innovation Solution
The method employs regular nodes within clusters to relay signaling messages cooperatively using a common channel, allowing cluster leaders to broadcast messages to neighboring clusters without relying on direct visibility or specific radio resource allocation based on network topology, through a distributed cooperative transmission mechanism.

1Productivity
If different communication paths are established depending on network topology to allow cluster leaders to reach neighboring cluster leaders, then inter-cluster communication is possible, but the quantity of radio resources required varies with topology making signaling inefficient
Solution Approach 1:
Regular nodes within clusters serve as intermediary relay nodes to forward signaling messages between cluster leaders. Instead of requiring direct visibility between cluster leaders, the signaling message travels through regular nodes that relay the message to neighboring clusters, eliminating the need for topology-dependent direct paths while maintaining consistent radio resource usage.
Solution Approach 2:
The signaling transmission path is segmented into multiple hops through regular nodes rather than requiring a single direct transmission between cluster leaders. This segmentation allows the signaling to be distributed across multiple relay nodes, each using consistent radio resources, thereby decoupling resource requirements from network topology.
2Reliability
If cluster leaders require direct visibility to exchange signaling information reliably, then communication reliability is improved, but this limits network topology flexibility and increases resource consumption
Solution Approach 1:
Regular nodes act as reliable intermediaries that guarantee message delivery between cluster leaders without requiring direct visibility. The relay mechanism ensures that signaling messages are transmitted through available regular nodes, maintaining reliability while adapting to any network topology where direct cluster leader visibility is not possible.
Solution Approach 2:
The signaling path is made dynamic by allowing regular nodes to adaptively relay messages based on current network conditions and topology. Rather than requiring fixed direct paths, the system dynamically routes signaling through available regular nodes, ensuring both reliability and topology versatility.
3Speed
If inter-cluster signaling is performed frequently to improve communication speed, then signaling responsiveness is improved, but radio resource consumption increases
Solution Approach 1:
Each cluster serves itself by having its regular nodes relay signaling messages to neighboring clusters using the cluster's own dedicated radio channel. This self-service mechanism eliminates the need for additional inter-cluster radio resources, allowing frequent signaling without proportional increases in resource consumption.
Solution Approach 2:
The dedicated radio channel within each cluster serves multiple functions: both intra-cluster communication and inter-cluster signaling relay. This multi-functionality allows the same radio resources to be used for both local cluster operations and external signaling, enabling frequent signaling without additional resource allocation.

AI summary
The invention relates to a method and system for broadcasting one or more signalling messages in a communication network comprising at least two clusters, characterised in that it comprises at least the following steps: at least one cluster leader of a first cluster transmits a signalling message M towards a set of nodes located in the cluster thereof, using a dedicated radio resource; the nodes of the first cluster, having received and decoded the signalling message M, relay said signalling message M towards one or more nodes of other clusters of the network which are within radio reach using a distributed cooperative coherent transmission mechanism, over a radio resource of a dedicated shared channel CS; said node or nodes, having received and decoded the signalling message M, transmit same to the cluster leader thereof using a distributed cooperative transmission method over a dedicated radio resource CHj.
