However, FL is vulnerable to model-poisoning attacks where malicious clients tamper with their local models to manipulate the global model. In this work, we investigate the resilience of the partial-sharing online FL (PSO-Fed) algorithm against such attacks. PSO-Fed reduces communication overhead by allowing clients to share only a fraction of their model updates with the server. We demonstrate that this partial sharing mechanism has the added advantage of enhancing PSO-Fed's robustness to model-poisoning attacks. Through theoretical analysis, we show that PSO-Fed maintains convergence even under Byzantine attacks, where malicious clients inject noise into their updates. Furthermore, we derive a formula for PSO-Fed's mean square error, considering factors like stepsize, attack probability, and the number of malicious clients. Interestingly, we find a non-trivial optimal stepsize that maximizes PSO-Fed's resistance to these attacks. Extensive numerical experiments confirm our theoretical findings and showcase PSO-Fed's superior performance against model-poisoning attacks compared to other leading FL algorithms.","PeriodicalId":56268,"journal":{"name":"IEEE Transactions on Signal and Information Processing over Networks","volume":"11 ","pages":"388-400"},"PeriodicalIF":3.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two main challenges associated with the delay in this area. One is that it causes the networks to oscillate close to the equilibrium. The other is that it causes the synchronization criterion to be very conservative, particularly when the impulses contain large (exceeding impulsive intervals) delays. To overcome these challenges, we propose the concept of equivalent impulsive sequence and the method of delayed impulsive sequence decomposition, respectively. Meanwhile, we establish a framework that equivalently transforms the networks with large delays into a collection of networks with small (shorter than impulsive intervals) delays. Particularly, this transformation is a sufficient and necessary condition, and thus does not induce any conservatism. Following this, we delineate the FxTS criteria for the networks containing synchronizing and desynchronizing impulses. Interestingly, it is shown that under some conditions, the large delay has no effect on the FxTS criterion of networks with synchronizing impulses, but destroys those of networks with desynchronizing impulses. Furthermore, we prove the necessity and rationality of the FxTS criterion. Finally, the conclusions are substantiated through numerical demonstrations.","PeriodicalId":56268,"journal":{"name":"IEEE Transactions on Signal and Information Processing over Networks","volume":"11 ","pages":"439-449"},"PeriodicalIF":3.0,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143913409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, we develop a modified version of DDAR with delayed information (DDARD), which considers the delays of both network communication and gradient calculation, enhancing the algorithm's flexibility in communication and iteration.

To address this game, we develop a distributed proportional-integral algorithm based on the coalition estimate strategy and the proportional-integral principle. Furthermore, when the communication resource is concretely quantified by bit rates in communication channels, we propose a coding-decoding-based distributed proportional-integral algorithm based on the distributed proportional-integral algorithm and coding-decoding rules for seeking the Nash equilibrium of multiple coalition games. It proves that both algorithms linearly and precisely converge to the Nash equilibrium in spite of limited communication resources. Then, the necessary and sufficient condition for the linear convergence of the proposed algorithm about the requirement of bit rates is presented. Moreover, the relationship between the bit rate and the convergence speed of the proposed algorithm is also theoretically explained. Lastly, the simulation in formation problems of unmanned vehicle swarms is presented to demonstrate the effectiveness of proposed algorithms.","PeriodicalId":56268,"journal":{"name":"IEEE Transactions on Signal and Information Processing over Networks","volume":"11 ","pages":"450-459"},"PeriodicalIF":3.0,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144090763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We discuss three different categories of consensus algorithms: leaderless algorithms of first and second orders, and first-order leader-follower algorithm. Firstly, we derive exact solutions for leaderless network coherence in the first and second orders. Secondly, we design various leader allocation schemes for the first-order leader-follower networks, obtaining expressions correlated with the network scale <inline-formula><tex-math>$N$</tex-math></inline-formula>, the double-ring cardinalities <inline-formula><tex-math>$p$</tex-math></inline-formula> and <inline-formula><tex-math>$q$</tex-math></inline-formula>, and the number of leaders <inline-formula><tex-math>$k$</tex-math></inline-formula>. Thirdly, we conduct numerical simulations and robustness analyses to explore the impact of leader quantity and topology structure on network coherence. Specifically, the conclusions are as follows: (1) When <inline-formula><tex-math>$N$</tex-math></inline-formula> decreases, an increase in <inline-formula><tex-math>$k$</tex-math></inline-formula> demonstrates improved network coherence. (2) The smaller the difference between <inline-formula><tex-math>$p$</tex-math></inline-formula> and <inline-formula><tex-math>$q$</tex-math></inline-formula>, the better the coherence.

(4) Uniform distribution of <inline-formula><tex-math>$k_{1}$</tex-math></inline-formula> and <inline-formula><tex-math>$k_{2}$</tex-math></inline-formula> leads to optimal coherence.

We propose a distributed normalized least mean square (LMS) algorithm, where each node updates its own estimate by the least mean square term, and sums the differences between its own estimate and the estimates of its neighbors with additive and multiplicative communication noises by the consensus term. By the algebraic graph theory and the stochastic analysis techniques, we obtain sufficient conditions for the boundedness of the tracking error. For a sequence of general random graphs, if the random graphs and the regression matrices satisfy the stochastic spatio-temporal persistence of excitation condition, then the mean-square tracking error is bounded by choosing appropriate constant gains. Furthermore, for conditional balanced graphs and Markovian switching graphs, we give sufficient conditions such that the persistence of excitation condition holds.
