Towards Self Healing Publish/Subscribe System on MANET

This paper presents a novel approach for Quality of Service aware publish/subscribe systems on Mobile Adhoc 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.
