Abstract
In this paper, we propose an analytical framework for monitoring and analyzing QoS of publish/subscribe systems on MANET. Our framework copes with intermittent connectivity frequently occurring in MANET and provides statistical methods allowing detecting QoS degradations affecting links between brokers at the middleware layer. Besides, our analytical framework identifies QoS degradation source which enables to repair the system. The proposed framework is extensively evaluated with simulation experiments. Simulations results show its efficiency.

Abstract
This paper aims at designing of adaptive framework for supporting collaborative work of different actors in public safety and disaster recovery missions. In such scenarios, firemen and robots interact to each other to reach a common goal; firemen team is equipped with smart devices and robots team is supplied with communication technologies, and should carry on specific tasks. Here, reliable connection is mandatory to ensure the interaction between actors. But wireless access network and communication resources are vulnerable in the event of a sudden unexpected change in the environment. Also, the continuous change in the mission requirements such as inclusion/exclusion of new actor, changing the actor's priority and the limitations of smart devices need to be monitored. To perform dynamically in such case, the presented framework is based on a generic multi-level modeling approach that ensures adaptation handled by semantic modeling. Automated self-configuration is driven by rule-based reconfiguration policies through ontology.

Abstract
In group-wide collaborative environment, managing the adaptive communication is a challenging task. It implies the monitoring of sudden change in the activities while providing a solution to maintain the connection with the available resources. In this work, we design a software agent that supports autonomic computing to ensure reliable communications among the mobile devices and Autonomous Ground vehicles (AAV). This issue is addressed in the context of save and rescue missions carried out during natural disasters such as floods and forest fires by human and voluntary operators within the framework of wireless environment. The paper focuses the autonomic functionalities of the components used to monitor, analyze, plan, and execute the adaptive mechanisms in case of evolution (mission/environment). We distribute this agent among devices and vehicles to ensure the adaptive task and it is tackled by using appropriate policies used to select the decision and executed without manual intervention. This research is applied to a Crisis Management System (CMS) within the context of the French RTRA project (ROSACE).

Abstract
This paper presents a novel approach for Quality of Service aware publish/subscribe systems on Mobile Ad-hoc Network. Crisis management application seems to be a relevant case study to our approach. On the one hand, our proposed solution monitor the system and analyzes his state towards predicting Quality of Service degradations. Real time prediction is based on the Auto Regressive Integrated Moving Average Formula. On the other hand, our solution defines new reconfiguration actions to be applied once Quality of Service degradation are predicted. In order to evaluate the proposed reparation actions, we define a protocol describing different transformation rules for adaptation using graphs and graph grammar. The Graph Matching and Transformation Engine (GMTE) is used to apply rules to the publish/subscribe system.
