Distributed Synchronization for OFDMA - Based Wireless Mesh Networks
© 2014 Jihyung Kim et al. 1 http://dx.doi.org/10.4218/etrij.14.0113/0223 In this paper, we propose a distributed synchronization algorithm for wireless mesh networks based on orthogonal frequency division multiple access. For time and frequency synchronization, a node requests its neighbor nodes for a change of fast Fourier transform starting points, transmission times, and carrier frequencies ...
متن کاملDistributed Synchronization Technique for OFDMA-Based Wireless Mesh Networks Using a Bio-Inspired Algorithm
In this paper, a distributed synchronization technique based on a bio-inspired algorithm is proposed for an orthogonal frequency division multiple access (OFDMA)-based wireless mesh network (WMN) with a time difference of arrival. The proposed time- and frequency-synchronization technique uses only the signals received from the neighbor nodes, by considering the effect of the propagation delay ...
متن کاملDistributed Frequency Synchronization for Global Synchronization in Wireless Mesh Networks
In this paper, our focus is to assure a global frequency synchronization in OFDMA-based wireless mesh networks with local information. To acquire the global synchronization in distributed manner, we propose a novel distributed frequency synchronization (DFS) method. DFS is a method that carrier frequencies of distributed nodes converge to a common value by repetitive estimation and averaging st...
متن کاملDistributed Event Synchronization for Diagnosing Wireless Mesh Networks
The possibility for connecting mobile end-devices and mobile automation facilities leads to fast deployment of Wireless LANs in factory automation, for instance to connect hand-scanners, mobile operation-terminals, automated guided vehicles. In these applications, WLAN is currently used for transparently prolonging a wired connection at the end of a control line (e.g. for controlling a mobile r...
متن کاملA New Method based on Intelligent Water Drops for Multicast Routing in Wireless Mesh Networks
In recent years a new type of wireless networks named wireless mesh networks has drawn the attention of researchers. In order to increase the capacity of mesh network, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi channel wireless mesh networks. Therefore, the main challenge of these networks is how to properly assign the channels to the radios. O...
