Context-Aware Content Delivery through a Mobile Ad Hoc Network Using the Publish/Subscribe System

Due to the highly dynamic nature of a mobile ad hoc network (MANET) and the node mobility, as well as the possibility of short- and long-term disconnections, the most important point is subscriber routing and information delivery in a short period of time. Therefore, in this study, we proposed the geographic zone routing (GZR) protocol which used the publish/subscribe system for receiving and sending information, a positioning system for determining the node location, and the zoning to structure a MANET in order to achieve the high packet delivery rates. The GZR can increase the rate of successful packet delivery and reduce the end-to-end delay and it performs well in large-scale dynamic networks.
