ZAFAR, H. et al. An Effective Capacity Estimation Scheme in IEEE802.11-based Ad Hoc Networks. J. appl. res. technol [online]. 2012, vol.10, n.6, pp.865-870. ISSN 2448-6736.

Capacity estimation is a key component of any admission control scheme required to support quality of service provision in mobile ad hoc networks. A range of schemes have been previously proposed to estimate residual capacity that is derived from window-based measurements of channel estimation. In this paper a simple and improved mechanism to estimate residual capacity in IEEE802.11-based ad hoc networks is presented. The scheme proposes the use of a ‘forgiveness’ factor to weight these previous measurements and is shown through simulation-based evaluation to provide accurate utilizations estimation and improved residual capacity based admission control.

Palavras-chave : admission control; capacity estimation; mobile ad hoc networks; quality of service.
