Applying real time applications with deadline guarantee for Ad Hoc network seems to be a difficult
challenge and to be an impossibility in general. This is due to the features of such networks.
However, if we make an assumption on node mobility, traffics and reliability with predictable
features, we can get real time guarantee. That is the goal of our present work.
In this paper, we present a new routing algorithm based on DSR to get the guarantee of Hard real
Time traffics. This algorithm is based on a node resource reservation for each traffic path. An
admission control is made to preserve the reserved node resources and is adapted to node
mobility by preventing path breaking. Our routing protocol is implemented under NS2 and
simulation results perform more stable time features than classical routing.
