Abstract :
A Framework for Integrated Routing, Scheduling and Traffic Management (FIRST) in Ad Hoc Networks is introduced. Unicast and multicast routes are established in coordination with the scheduling of transmissions and bandwidth reservations in a way that bandwidth and delay guarantees can be enforced on a per-hop and end-to-end basis. Results from detailed simulation experiments show that, compared to a protocol stack consisting of 802.11 DCF for channel access, AODV or OLSR for unicast routing, and ODMRP for multicast routing, FIRST attains similar or better performance for elastic traffic, and up to two orders of magnitude improvement in end-to-end delays, with twice the amount of data delivery for real-time traffic.
