As wireless networks become more prevalent, users will demand the same applications that are currently available in wired networks. Further, they will expect to receive a quality of service similar to that obtained in a wired network. Included in these applications are real-time applications such as voice over IP and multimedia streams. To enable the support of applications that require real-time communication in ad hoc networks, congestion must be prevented so that the needed quality of service can be provided. An admission control mechanism is an essential component of the quality of service solution. Unfortunately, current admission control solutions encounter problems during mobility, often resulting in unacceptable disruptions in communication. To solve this problem, we apply multi-path routing mechanisms that maintain alternate paths to the destination and propose a new admission control protocol. We show through simulation that our solution is able to prevent communication disruptions and meet the QoS needs of applications better than previous solutions.
