Abstract

This work presents a tightly-coupled packet scheduling and routing algorithm to effectively transmit delay-sensitive media over mobile ad hoc network. First, packet urgency, node urgency, and route urgency are defined based on the end-to-end delay requirement of each packet and the number of hops over a route. Packet scheduling algorithm and packet drop policy are designed to maximize the number of packets delivered in the tolerable delay bound and minimize their node urgency at each node simultaneously. Finally, the routing algorithm is implemented to search for a route with the minimum route urgency.
