{"title":"An energy-optimization topology control for three-dimensional wireless sensor networks","authors":"Mason Thammawichai;Thiansiri Luangwilai","doi":"10.23919/JCN.2023.000050","DOIUrl":"https://doi.org/10.23919/JCN.2023.000050","url":null,"abstract":"Energy optimization routing protocol is considered an essential problem in wireless sensor networks (WSNs) as it can affect the network lifetime. Most of the existing routing algorithms are designed for two-dimensional networks, which cannot be transferred to three-dimensional WSNs. Due to a lack of knowledge about the third dimension, 2D routing algorithms perform badly in a real-life 3D environment such as a hill, an urban area, an underground area, an underwater area, and so forth. These networks also suffer from problems such as routing stretch, energy efficiency, and load balancing. Therefore, in this paper, a mixed integer linear programming is formulated as an optimal WSN topology control problem to address the energy optimization routing problem in 3D terrain. The proposed method is a self-organized network that uses clustering and sleep/wake-up schemes to maximize the network lifetime and minimize energy consumption. Simulations revealed that our algorithm is robust to various terrains and significantly increases the network lifetime when compared to a well-known protocol, i.e., the multi-hop low energy adaptive clustering hierarchy (LEACH), with an improved average of 44.94 %. The results also suggested that the energy balancing strategy provided better solutions than the minimizing total energy scheme due to the optimal load balancing scheme of the cluster head selection at each decision round. Furthermore, our global optimal solutions can serve as a benchmark for all heuristic algorithms. Though the number of variables in our optimization problem grows nonlinearly with the number of sensor nodes, the computation time is rather practical as the problem is linear.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"25 6","pages":"778-788"},"PeriodicalIF":3.6,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10387278","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139406648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The centralized max-weight policy is known to be nearly optimal in this setting; hence, our goal is to design a distributed carrier sense multiple access (CSMA) scheme that can mimic its performance. To that end, we propose a distributed protocol called Fresh-CSMA and show that in an idealized setting, Fresh-CSMA can match the scheduling decisions of the max-weight policy with high probability in each frame, and also match the theoretical performance guarantees of the max-weight policy over the entire time horizon. We then consider a more realistic setting and study the impact of protocol parameters on the probability of collisions and the overhead caused by the distributed nature of the protocol. We also consider the monitoring of Markov sources and extend our approach to CSMA protocols that incorporate age of incorrect information (AoII) instead of AoI. Finally, we provide simulations that support our theoretical results and show that the performance gap between the ideal and realistic versions of Fresh-CSMA is small.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"25 5","pages":"556-569"},"PeriodicalIF":3.6,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10323421","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138431110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the control-aware design of the wireless resource management for wireless networked control systems (WNCSs) is shown to be more effective from the application perspective than the conventional approaches. In WNCS, the controller monitors and actuates the plant through the status updates received from the sensor over the network. This work focuses on application-aware transmission scheduling over multi-hop networks for WNCSs. As an intermediate metric, we use age of information (AoI) that captures the freshness of the data on the controller. Being a widely adopted metric for real-time applications, AoI does not consider the particular goal of control applications. Nevertheless, AoI is tightly coupled with the estimation error at the controller that, in turn, directly impacts control performance. We derive the distribution of AoI in the multi-hop network that exploits a time-varying transmission schedule. Using this distribution, we express the expected estimation error to formulate a minimization objective for the scheduling. We propose exact and heuristic methods for solving the optimization and compare different approaches to resource allocation with respect to estimation error and control costs. The proposed scheduling algorithm improves the control performance by at least 15% compared to the scheduling minimizing AoI. Introducing the schedule variability over time allows for further performance improvement by 30% in scenarios with scarce network resources.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"25 5","pages":"688-698"},"PeriodicalIF":3.6,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10323430","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138431264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The BS has η discrete transmission power levels to communicate with the users and the adversary has m discrete blocking power levels to block the communication channels. The probability of successful transmission of an update packet depends on these power levels. The BS and the adversary have a transmission and blocking average power constraint, respectively. We provide a universal lower bound for the average age of information for this communication network.

In the PS queueing discipline, all the updates are served simultaneously and, therefore, none of of the jobs wait in the queue to get service. While AoI has been well studied for various queuing models and policies, less attention has been given so far to the PS discipline. We first consider the M/M/1/2 queue with and without preemption and provide closed-form expressions for the average AoI in this case. We overcome the challenges of deriving the AoI expression by employing the stochastic hybrid systems (SHS) tool. We then extend the analysis to the M/M/1 queue with one and two sources and provide numerical results for these cases.

The sampler generates a sample upon receiving a request from the controller and the sample requires further processing before transmission, hence is computation-intensive. This is mathematically modeled by a server called process server. After processing the sample, the status update packet is generated and sent to the transmitter for delivery to the sink. This is mathematically modeled by a server called transmit server. The service time of each packet at the transmit and process servers follow geometric distributions. Moreover, we consider that the servers serve packets under the blocking policy, i.e., whenever a server is busy at the arrival time of a new packet, the new arriving packet is blocked and discarded. We analyze the average age of information (AoI) for two fixed policies, namely, 1) zero-wait-one policy and 2) zero-wait-blocking policy. According to the former policy, the controller requests sampling when there is no packet in the system. According to the zero-wait-blocking policy, the controller requests a sample whenever the process server is idle. Furthermore, we develop an optimal control policy to minimize the average AoI using the tools of Markov decision process (MDP). In numerical results, we evaluate the performance of the policies under different system parameters. Moreover, we analyze the structure of the optimal policy.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"25 5","pages":"585-597"},"PeriodicalIF":3.6,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10323423","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138431263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A transmitter sends samples from an observed information source to a remote monitor over an unreliable wireless channel. The receiver, in turn, performs an action according to the state of the reconstructed source. We propose a state-aware randomized stationary sampling and transmission policy which accounts for the importance of different states of the information source, and their impact on the goal of the communication process. We then analyze the performance of the proposed policy, and compare it with existing goal-oriented joint sampling and transmission policies, with respect to a set of performance metrics. Specifically, we study the real-time reconstruction error, the cost of actuation error, the consecutive error, and a new metric, coined importance-aware consecutive error. In addition, we formulate and solve a constrained optimization problem that aims to obtain the optimal sampling probabilities that minimize the average cost of actuation error. Our results show that in the scenario of constrained sampling generation, the optimal state-aware randomized stationary policy outperforms all other sampling policies for fast evolving sources, and, under certain conditions, for slowly varying sources. Otherwise, a semantics-aware policy performs better only when the source is slowly varying.","PeriodicalId":54864,"journal":{"name":"Journal of Communications and Networks","volume":"25 5","pages":"657-669"},"PeriodicalIF":3.6,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10323428","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138431267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
