Dual-Mode Wireless Devices for Adaptive Pull and Push-Based Communication

2025-07-31

AI Summary

This paper addresses resource contention, high energy consumption, and insufficient real-time performance arising from the coexistence of query-driven (pull) and event-driven (push) communication modes in wireless devices. To resolve these challenges, we propose an adaptive dual-mode communication framework that dynamically coordinates pull-based responses and push-based preemptions within a unified time-frame structure. The framework incorporates a wake-up radio-assisted customized MAC protocol and formulates a system-level joint optimization model to simultaneously minimize control overhead, maximize communication success rate, and improve energy efficiency. Theoretical analysis characterizes the fundamental trade-offs between push and pull traffic under resource constraints. Experimental results demonstrate that the proposed approach reduces energy consumption by up to 30% compared to conventional schemes, while maintaining high transmission success rates for both push and pull traffic—thereby significantly enhancing context awareness and quality of service across diverse application scenarios.

Abstract

This paper introduces a dual-mode communication framework for wireless devices that integrates query-driven (pull) and event-driven (push) transmissions within a unified time-frame structure. Devices typically respond to information requests in pull mode, but if an anomaly is detected, they preempt the regular response to report the critical condition. Additionally, push-based communication is used to proactively send critical data without waiting for a request. This adaptive approach ensures timely, context-aware, and efficient data delivery across different network conditions. To achieve high energy efficiency, we incorporate a wake-up radio mechanism and we design a tailored medium access control (MAC) protocol that supports data traffic belonging to the different communication classes. A comprehensive system-level analysis is conducted, accounting for the wake-up control operation and evaluating three key performance metrics: the success probability of anomaly reports (push traffic), the success probability of query responses (pull traffic) and the total energy consumption. Numerical results characterize the system's behavior and highlight the inherent trade-off in success probabilities between push- and pull-based traffic as a function of allocated communication resources. Our analysis demonstrates that the proposed approach reduces energy consumption by up to 30% compared to a traditional approach, while maintaining reliable support for both communication paradigms.
