In order to guarantee the QoS for wireless ad hoc network

the QoS deterministic upper bounds need to be ac-curately calculated.The data flow entering the node was regulated by leaky bucket

and the node provided rate-latency service for the flow.The node’s backlog upper bound

the end-to-end upper delay bound and the end-to-end upper delay jitter bound had been derived for wireless ad hoc network based on the existing link throughput model using network calculus theory.For grid topology wireless ad hoc network

all simulated results for different data flows were bounded by theoretical results.These show the QoS performance upper bounds model perform well.
