A Framework for Multi-Hop Ad-Hoc Networking over Wi-Fi Direct with Android Smart Devices

引用

Communications and Network 2021年第4期13卷 143-158页

作者： Rémy Maxime Mbala Jean michel Nlong Jean-robert Kala Kamdjoug Department of Mathematics and Computer Science Faculty of Science The University of Ngaoundéré Ngaoundéré Cameroon Laboratory of Mathematics Computer Science and Applications Faculty of Science The University of Ngaoundéré Ngaoundéré Cameroon GRIAGES Catholic University of Central Africa Yaoundé Cameroon

The wide diffusion of mobile devices that natively support ad hoc communication technologies has led to several protocols for enabling and optimizing Mobile Ad Hoc Networks (MANETs). Nevertheless, the actual utilization of MANETs in real life seems limited due to the lack of protocols for the automatic creation and evolution of ad hoc networks. Recently, a novel P2P protocol named Wi-Fi Direct has been proposed and standardized by the Wi-Fi Alliance to facilitate nearby devices’ interconnection. Wi-Fi Direct provides high-performance direct communication among devices, includes different energy management mechanisms, and is now available in most Android mobile devices. However, the current implementation of Wi-Fi Direct on Android has several limitations, making the Wi-Fi Direct network only be a one-hop ad-hoc network. This paper aims to develop a new framework for multi-hop ad hoc networking using Wi-Fi Direct in Android smart devices. The framework includes a connection establishment protocol and a group management protocol. Simulations validate the proposed framework on the OMNeT++ simulator. We analyzed the framework by varying transmission range, number of hops, and buffer size. The results indicate that the framework provides an eventual 100% packet delivery for different transmission ranges and hop count values. The buffer size has enough space for all packets. However, as buffer size decreases, the packet delivery decreases proportionally.

Improve Image Decoding in Lightweight Environment Using a Coroutines Based Approach

引用

Journal of Computer and Communications 2020年第10期8卷 60-74页

作者： Rodrigue Saoungoumi-Sourpele Jean michel Nlong Jean-robert Kala Kamdjoug Glen Vernyuy Yufui Department of Mathematics and Computer Science ENSAI University of Ngaoundere Ngaoundere Cameroon Department of Mathematics and Computer Science FS University of Ngaoundere Ngaoundere Cameroon GRIAGES Catholic University of Central Africa Yaounde Cameroon Department of Computer Engineering IUT University of Ngaoundere Ngaoundere Cameroon

The JPEG2000 still image compression standard, while providing a remedy for the many shortcomings of its predecessor JPEG, is still slow to establish itself on the Internet. This problem is mainly due to the complexity of the COder-DECoder (CODEC) which implies its non-adoption by large firms and platforms in the field of image acquisition, processing and transmission. Indeed, the encoding and decoding process consumes a lot of CPU, memory and energy resources and takes a lot of computing time. The objective of this paper is to propose a model for decoding jpeg2000 on lightweight devices running on the Android mobile operating system. This implementation uses coroutines, which are a lightweight process model with reduced resource consumption costs compared to conventional AsyncTask threadsets. The model minimizes decoding time while minimizing CPU and memory usage, resulting in a fast and energetically economical decoded image. The results of integrating the coroutines from the main thread into the decoding process instead of the AsyncTask from the main thread produced better performance in terms of computation time, CPU and memory utilization. Indeed, the use of our model has led to a gain of around 23.41% in execution time, 9.8% in CPU utilization rate and 18.56% in memory utilization rate, compared to the model proposed in the literature which uses the threads.

In a context marked by the proliferation of smartphones and multimedia applications, the processing and transmission of images have become a real problem. Image compression is the first approach to address this problem, it nevertheless suffers from its inability to adapt to the dynamics of limited environments, consisting mainly of mobile equipment and wireless networks. In this work, we propose a stochastic model to gradually estimate an image upon information on its pixels that are transmitted progressively. We consider this transmission as a dynamical process, where the sender pushes the data in decreasing significance order. In order to adapt to network conditions and performances, instead of truncating the pixels, we suggest a new method called Fast Reconstruction Method by Kalman Filtering (FRM-KF) consisting of<

作者： michel Durand-Delga 8 rue Charles-Lefebvre F 77210 Avon France.

The Algiers Congress came between the one held in London in 1948 （see Triimpy, 2004） and the one in Mexico （1956）. It was the second in Africa, after the one in Pretoria, South Africa （1929）. The plenary meeting was held in Algiers between 8 and 15 September, 1952. It brought together 1,129 participants （from the 2,910 who registered）, coming ,from 82 countries. The Presidency was held by Professor Charles Jacob, a Member of the Academie des Sciences （Paris）. The position of Secretary-General was in the safe hands of robert Laffitte, Professor in the Faculty of Science at the University of Algiers. The scientific sessions had 17 sections. In addition to a cruise excursion held before the Congress there was a total of 44 excursions held before and after the Algiers meeting in the territories then under French administration： Algeria, Morocco, Tunisia, and the dependencies of the Sahara region and West Africa.

Structural analogues of bicyclic peroxides belonging to the G factors family have been synthesised under Mannieh type conditions, followed by an autoxidation step furnishing exclusively the peroxide. As electron transfer from heine or free iron to peroxide is the first step in the mode of action ofartemisinin -like compound, Fe（fl） induced reduction was studied and the reactivity of the intermediate C-centered radical formed was correlated to the antimalarial activity. Dissociative electron transfer was studied by electrochemistry and allowed the evaluation of the standard reduction potentials and other pertinent thermochemical information. These bicyclic peroxides were evaluated in vitro against Plasmodium falciparum and revealed moderate to good activity.
