Due to mobility features of Ad Hoc networks, it becomes too difficult to guarantee delay requirements for real time applications across such networks. However, such real time guarantees can be optimally achieved with a reasonable presumption on node mobility, network traffic and reliability with predictable features. In this paper, we present a routing algorithm to achieve the guarantees for Hard real time network traffic, based on Dynamic Source Routing (DSR). It implements a node resource reservation policy along each traffic path. Admission control is performed with preservation of reserved node resources and is adapted to node mobility ultimately preventing path breaking. Our routing protocol is implemented under network simulator ns2 and simulation results are demonstrated with performance evaluation.
