Consequently, this study proposes a novel anti-interference LoRa physical layer communication model to reduce the Bit Error Rate (BER) under extremely low Signal-to-Noise Ratio (SNR) conditions in LoRa communication. The model incorporates Low-Density Parity-Check (LDPC) codes as the channel coding scheme and integrates soft Chirp Spread Spectrum (CSS) demodulation with the Log-Likelihood Ratios Belief Propagation (LLR-BP) decoding algorithm. A key component of the model is the Enhanced LLR-BP (ELLR-BP) algorithm, which dynamically adjusts LLR values during iterative decoding based on variations in SNR and Spreading Factor (SF), enabling enhanced BER performance in challenging environments. Additionally, the model introduces realistic channel effects, including fading and Co-SF interference, into the simulation framework. MATLAB simulations demonstrate the model’s effectiveness: LDPC coding improves the SNR threshold by approximately 1 dB and reduces the BER by more than 3% compared to traditional Hamming coding. When BER <inline-formula> <tex-math>${=} ,, 10{^{-}4 }$ </tex-math></inline-formula>, the proposed ELLR-BP algorithm achieves a gain of 0.4097 dB and reduces the BER by 0.54% to 0.81% compared with the LLR-BP algorithm. Similarly, the proposed anti-interference model significantly improves performance under Rayleigh channels and provides better resistance to Co-SF interference than standard LoRa.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"9 3","pages":"889-899"},"PeriodicalIF":6.7,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Addressing the lack of dynamism in decision-making during communications counter operations, in this paper, we customize the confrontation process between the communicator and the jammer as a Stackelberg game, where the communicator is the leader and the jammer is the follower. The game process is partitioned into time slots, and to obtain the best strategies of both in each time slot, we propose metrics to evaluate their utilities. The optimization problem is then constructed with the objective function of maximizing their utility metrics. Intelligent reflecting surface (IRS) is introduced to the communication process in order to improve the leader’s immunity to interference. A new optimization method is proposed in this paper to decompose and transform the optimization problem to finally obtain an asymptotic optimal solution. In addition, this paper proves that at least one Stackelberg equation exists, and the communicating party can always make the best decision after the interfering party makes the best decision. Finally, the empirical findings presented in this paper further substantiate that the gaming process ultimately reaches equilibrium. With the assistance of IRS, the communication pair saves power consumption while enhancing its anti-jamming capability.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"9 3","pages":"1280-1293"},"PeriodicalIF":6.7,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144880610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the distributed detection problem in WSN, the censoring technique has been proposed as an energy-efficient transmission strategy. However, most current detection schemes with censoring do not consider the quantization operations in actual communication systems to further save the transmission energy in actual communication systems. In this paper, we propose two energy-efficient detection schemes including a common censoring-quantization strategy and two different detectors. This censoring-quantization strategy aims to reduce the energy consumption of transmitting observations. It is modeled as a three-state equivalent transmission strategy at sensors, with the states being keeping silent, transmitting “1”, and transmitting “−1”. To fully explore the advantage of this strategy, we design two detectors, namely the Censoring-Quantization Maximum-Likelihood (CQ-ML) detector and the Censoring-Quantization Locally Most Powerful Test (CQ-LMPT) detector, respectively for two scenarios, which correspond to whether the fusion center (FC) knows the parameters of the Phenomenon of Interest (POI). We further analyze the theoretical performance of our schemes to provide the optimal censoring-quantization thresholds. Finally, experimental results demonstrate the effectiveness of our schemes and highlight the significant energy consumption reduction with negligible performance loss.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"9 3","pages":"1079-1091"},"PeriodicalIF":6.7,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144880560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimal beamwidth and receiver Field of View (FOV) values are identified to maximize energy and minimize SER.

Additionally, the proliferation of Internet of Things (IoT) has facilitated the development of complex multi-user, multi-edge server environments. In these settings, the interdependence of application tasks makes computational offloading and resource allocation decision-making challenging, but crucial for optimizing energy efficiency. As a response, in this paper, we propose an Energy-Aware Multi-user Dependent Task Offloading and Resource Allocation (EMDTORA) scheme for IoT-MEC infrastructures. First, we formulate an offline, task offloading, multi-objective optimization problem that aims to minimize the user devices’ energy consumption and experienced delay under given constraints. Given the NP-hardness of the problem, we devise an online framework that combines a Graph Attention Networks (GAT)-based mechanism, which captures the in-depth dependency structure of the applications, with an actor-critic off-policy Deep Reinforcement Learning (DRL) algorithm to approximate the optimal solution. Through extensive simulation we highlight the potency of the proposed scheme, as EMDTORA outperforms various baselines by successfully balancing the trade-off between energy consumption and delay minimization, under dynamic network conditions.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"9 3","pages":"1453-1469"},"PeriodicalIF":6.7,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed technique optimizes the precoding at the multi-LED transmitter, RIS tuning parameters, and time-slot allocation parameters for each cluster to maximize the system’s energy efficiency (EE). The EE optimization problem is solved through the block coordinate descent (BCD) framework, which splits the optimization problem into two blocks. An alternating optimization (AO) framework is used in the first block to optimize the transmit precoding through conic quadratic programming (CQP) and RIS tuning parameters through a semidefinite programming (SDP) technique based on the surrogate optimization method.

Traditional approaches either neglect gateway energy consumption or struggle to balance energy efficiency with delay requirements. To address this, we introduce the Dual-interface Gateway Activation (DGA) scheme, a significant advancement enhancing IoT gateway energy management via interactive cooperation between ZigBee and Wi-Fi. DGA’s core innovation lies in its dual-interface design and heterogeneity-aware activation strategy. By leveraging coexisting low-power ZigBee communications, DGA dynamically activates the gateway’s high-power Wi-Fi interface only when necessary for data reception, effectively decoupling power consumption from continuous Wi-Fi operation. Meanwhile, DGA conservatively schedules high-reliability Wi-Fi sessions to augment unreliable ZigBee communications, thereby ensuring prompt gateway activation for delay-bounded data delivery under varying network conditions. This innovative approach not only guarantees high energy efficiency but also low latency, overcoming the limitations of single-interface gateways. Experimental validation of our prototype system demonstrates DGA’s superior performance, achieving up to 62.1% and 45.9% reductions in gateway energy consumption compared to state-of-the-art single-interface and dual-interface solutions, respectively. Additionally, DGA attains lower node energy consumption, further highlighting its potential to enable more energy-efficient IoT networks.","PeriodicalId":13052,"journal":{"name":"IEEE Transactions on Green Communications and Networking","volume":"9 3","pages":"1064-1078"},"PeriodicalIF":6.7,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144880561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
