Evaluation of the BRuIT protocol

In [C. Chaudet et al., Feb. 2002], BRuIT, a bandwidth reservation protocol for ad hoc networks that takes into account the influence of distant emitters on medium availability, has been described in broad outline. This article presents enhancements and evaluations of BRuIT. We justify the choices made in BRuIT, especially on the range of available resources information, with a stochastic geometry analysis. The simulation results show that this protocol enhances the network usage by not overloading the medium at the cost of longer routes and a larger establishment time. Nevertheless, the load is better balanced in the network, therefore network capacity is not overloaded. This results in more stable routes and less control traffic as almost no reconstructions are needed.
