MTRSRP: Joint Design of Multi-Triangular Ring and Self-Routing Protocol for BLE Networks

Area of Science:

• Computer Science
• Network Engineering
• Wireless Communication

Background:

• Existing multiring scatternet protocols face challenges in optimizing throughput and network efficiency.
• Decentralized strategies are needed to improve data transmission and reduce overhead in complex network topologies.

Purpose of the Study:

• To introduce the multi-triangular ring and self-routing protocol (MTRSRP) for enhanced multiring scatternet performance.
• To establish an effective multi-triangular ring topology through leader election and scatternet formation phases.
• To optimize packet transmission paths and reduce network overhead using a self-routing addressing scheme.

Main Methods:

• Implemented a two-phase approach: leader election for coordinator selection and scatternet formation for topology establishment.
• Utilized broadcast and unicast messaging for neighbor information exchange, coordinator election, and piconet connection.
• Incorporated intra- and inter-bridge nodes for piconet interconnection and a self-routing addressing scheme for efficient packet delivery.

Main Results:

• MTRSRP demonstrated superior performance in transmission rate, packet delay, and delivery ratio compared to cluster-based on-demand routing and Bluetooth low-energy mesh.
• Dual-bridge connectivity in MTRSRP significantly improved key network transmission metrics.
• The self-routing scheme effectively optimized packet transmission paths within the triangular ring architecture.

Conclusions:

• MTRSRP significantly enhances throughput and network efficiency in multiring scatternets.
• The multi-triangular ring topology and self-routing capabilities provide a robust and efficient communication strategy.
• MTRSRP offers a promising solution for improving wireless network performance in scatternet environments.
