A Probability-Based Method for Resources Advanced Reservation in Wireless Ad Hoc Networks

Ad hoc networks are wireless networks composed of mobile devices with limited power and transmission range. Advance reservations are a useful method to allocate resources of various kinds in many different environments, and especially be useful for wireless ad hoc networks that require network quality of service, which need advance reservation to support handovers for streaming video. It is key in guaranteeing that enough resources will be available in the wireless ad hoc network when a new flow is to be set between a source and a destination. In this paper, we evaluate several methods for supporting advanced reservation in wireless ad-hoc networks, and propose a probability-based method for resources advanced reservation (PMRAR). This method can provide resource reservation more efficiently and cost-effectively, and make the resource management more powerful and practical for wireless ad-hoc networks.
