Establishing content-based publish/subscribe in the resource constrained and failure prone environment of Mobile Ad-Hoc Networks (MANETs) is a highly challenging task. Movement of nodes and network partitioning can require frequent and possibly expensive reorganizations of the publish/subscribe system. Many approaches towards publish/subscribe in MANETs either rely explicitly on location information, or are characterized by a high subscription and publication overhead. In this paper we present preliminary research on how geographical distribution of subscriptions may help to overcome some shortcomings of both approaches.
