A Real Time Subject Routing Protocol for MANETs

Marcelo M. SobralLeandro Buss Becker

Applications using Mobile Ad Hoc Networks (MANETs) and requiring real-time guarantees must rely on predictable communication services. However, due to mobility and topology modifications, it is hard to keep updated the information about resource demands throughout the network. This impacts directly the real-time provisioning, both in the MAC and in the network layers, which must adapt themselves to network changes in a timely manner. Moreover, subject and content-based is widely used in such scenarios. The uncoupling among producers and consumers avoids the overhead in the network from keeping individual routes. This paper introduces the Real-Time Subject Routing Protocol (RTSR), a subject-based routing protocol that uses dynamic resource reservation to implement a timely delivery of messages in MANETs.
