Wireless Base Station Network Energy Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-hop routing algorithms for energy-constrained networks are inefficient when nodes must communicate with a cloud server indirectly through a low-energy transmission chain, as they require frequent updates and energy-consuming broadcasts to determine the transmission route.
Innovation Solution
A wireless base station network optimizes energy efficiency by determining an optimal transmission sequence in the form of a linear daisy chain, where each base station only communicates with its predecessor and successor, using RF link attenuation measurements to conserve energy and employing Sequential Interruption Logic for failure detection without direct communication with the server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If each node stores complete routing information of the entire network, then route determination is very fast, but every node must update its routing table and consume energy whenever network topology changes
Solution Approach 1:
The patent segments the network routing information into localized portions. Instead of each node storing complete network routing tables, nodes only store routing information for their local vicinity. The system introduces intermediate anchor nodes that store and manage routing information for larger network segments. This segmentation allows fast local route determination while reducing the frequency and energy cost of routing table updates across the entire network.
2Loss of information
If a single node floods the entire network with route request messages or several nodes broadcast packets, then the transmission route can be determined, but energy is consumed for broadcasting
Solution Approach 1:
The patent introduces anchor nodes as intermediaries in the routing process. Instead of flooding the entire network with route request messages, route requests are directed through these intermediary anchor nodes that maintain knowledge of network topology. This mediator approach enables route discovery without requiring extensive broadcasting, significantly reducing energy consumption while still achieving complete route information discovery.
3Measurement precision
If base stations transmit packets with source identification, then routing accuracy is improved, but power consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing routing paths through anchor nodes before actual data transmission occurs. Route requests with source identification are sent in advance to determine the optimal path, and once the route is established, data packets can be transmitted along this pre-determined path with reduced identification overhead. This preliminary route determination maintains routing accuracy while reducing the power consumption associated with continuous source identification in every packet.

Function Achieved in This Case
This approach significantly reduces energy consumption by minimizing the need for nodes to store complete routing information and reducing the frequency of energy-intensive broadcasts, while maintaining reliability and efficiency in data transmission, even in areas with poor radio signal penetration.
Implementation Method 1
Each base station (of a plurality of base stations) may receive an RF link attenuation measurement, e.g., by performing a received signal strength indication (RSSI)
Data Source
AI summary
The present invention is directed to optimization and failure detection of a wireless base station network. Based on an RF link attenuation measurement, e.g., a Received Signal Strength Indication (RSSI) measurement, a server determines an optimal transmission sequence. For each base station of the optimal transmission sequence, a predecessor and a successor are designated. Each base station of the sequence generates a packet. The most distant base station (relative to the server) transmits its packet to its successor. Each base station of the sequence (in turn) receives the packet from its predecessor, combines the received packet with its own generated packet, transmits the combined packet to its successor, and so on until the combined packet is relayed to a super base station at the end of the sequence. The super base station transmits the packet to the server. Based on the packet size, the server can ascertain which base station (if any) failed.
