Abstract
In this paper, we present , an event system designed for mobile ad hoc networks that supports the publish-subscribe model as well as point-to-point and point-to-multipoint message sending. Chapar supports event persistency to resist transient disconnections and network partitioning. Following a cross-layer approach, Chapar is designed as an overlay network that uses the Multipoint Relays (MPRs) defined in OLSR as distributed brokers, and uses the OLSR routing table to disseminate the events. It therefore benefits from the way OLSR handles topology changes. The implementation performance is promising in the sense that no extra signaling is generated by mobility support and the generated overlay traffic is considerably less than the underlying routing protocol.
