ALZATE, Marco A  e  TAMARA, Leydi J. Control of admission for AD HOC mobile network based on estimates available bandwidth. Tecnura [online]. 2011, vol.15, n.29, pp.24-34. ISSN 0123-921X.

The admission control algorithms in wired networks can monitor traffic on each of the links point-to-point in order to determine the available bandwidth for the flows along different routes and base their decision the difference between the available bandwidth and the bandwidth required. Unfortunately, this is not possible in a mobile ad hoc network (MANET) for several reasons, among which two stands out: (1) In the MANET, a transfer between two adjacent nodes consumes the bandwidth of many neighbors, which difficult to estimate the available bandwidth. (2) A node that supports has an effect on the network that goes far beyond reducing the bandwidth available in a predictable amount, on the contrary, it can affect the spatial distribution of existing flows and the likelihood of collision. In these conditions, it is easy for an admission control algorithm to determine the magnitude of the flows should be admitted to exploit the resources of communication without saturating the network. This is a refection article where we discuss some major issues associated with the interaction between these two fundamental problems and propose a new approach to investigation.
