Problem of Standardization of Configuration Data in Wireless Sensor Networks: The Case of Routing Protocols

Wireless Sensor Network 2012年第7期4卷 177-184页

作者： thomas djotio ndie Judith Soulamite Nouho Noutat Management and Security of Network and System Services University of Yaoundé Yaoundé Cameroon

The exploitation of Wireless Sensor Networks (WSN) is constrained by limited power, low computing power and storage and short-range radio transmission. Many routing protocols respecting these constraints were developed but, it still lacks formal and standardized solutions being able to help in their configuration. The configuration management that responds to this concern is very important in this type of network. It consists of the definition of data models to configure and is very necessary for the good network performance. Tangible results were obtained in traditional networks with the emergence of NETCONF and YANG standards, but on the best of our humble knowledge there are none yet in WSNs. We propose in this paper wsn-routing-protocol, a YANG data model for routing protocols configuration in WSNs. Following our model, we propose two YANG configuration data models based on the latter: they are respectively aodv for AODV and rpl for RPL.

MDA (Model-Driven Architecture) as a Software Industrialization Pattern: An Approach for a Pragmatic Software Factories

引用

Journal of Software Engineering and Applications 2010年第6期3卷 561-571页

作者： thomas djotio ndie Claude Tangha Fritz Ekwoge Ekwoge 不详

In this paper we show that the MDA can be considered as a software industrialization pattern (or a software factory). Nearly all industries today are haunted with how to reduce costs, improve quality, faster time-to-market and to maximize profits. These challenges are particularly relevant to the software industry, because it still lags behind other technology sectors as regards industrialization and the timely delivery of software products. Most software are still of poor quality, always finished after deadlines (most don’t finish at all), and are very labour intensive. Here, we discuss the MDA as an approach that may help solving at the same time both problems of industrialization and ever-changing software infrastructures. We propose a MDA Engine based on a real case study in an IT services company. It is a proposal for a framework to create custom MDA tools, based on XMI, XSLT and the Visitor Pattern.

Mobile Applications Provisioning Using Bluetooth Wireless Technology

引用

Journal of Software Engineering and Applications 2011年第2期4卷 95-105页

作者： thomas djotio ndie Claude Tangha Tam Sangbong Armstrong Formenah Kufor 不详

In this paper, we propose a cheap means for propagating mobile application using Bluetooth, a convenient short range wireless technology. Today, one of the main problems about mobile technology is about implementing automatically the software in the multiple and various type of phones devices, irrespective of the phone model (Nokia, Samsung, iPhone, etc.). There are many ways of doing OTA like by SMS. This approach allows providing an http download link by SMS but, we are limited by the maximum size one can have to build an application and send it trough this means. This approach is also expensive because data sources are expensive. Within the context of mobile social networking and proximity marketing, we come up with an original way of provisioning mobile applications using Bluetooth. We use anybody who is already a subscriber of an application to become an ambassador of it. The application is self-replicating and distributing in itself and sending back results. It ethically acts like a virus or a disease. A prototype is built to validate the proposed methodology.

MAMNID: A Load Balance Network Diagnosis Model Based on Mobile Agents

引用

Journal of Information Security 2012年第4期3卷 281-294页

作者： thomas djotio Ndié Claude Tangha Guy Bertrand Fopak Lirima/Aloco University of Yaounde 1 Yaounde Cameroon Lirima/Masecness University of Yaounde 1 Yaounde Cameroon

In this paper, we propose MAMNID, a mobile agent-based model for networks incidents diagnosis. It is a load-balance and resistance to attack model, based on mobile agents to mitigate the weaknesses of centralized systems like that proposed by Mohamed Eid which consists in gathering data to diagnose from their collecting point and sending them back to the main station for analysis. The attack of the main station stops the system and the increase of the amount of information can equally be at the origin of bottlenecks or DDoS in the network. Our model is composed of m diagnostiquors, n sniffers and a multi-agent system (MAS) of diagnosis management of which the manager is elected in a cluster. It has enabled us not only to reduce the response time and the global system load by 1/m, but also make the system more tolerant to attacks targeting the diagnosis system.
