Bandwidth Reservation in Mobile Adhoc Networks
In: IEEE Wireless Communications and Networking Conference (WCNC 2012), edited by IEEE, Paris, France.
Bandwidth reservation is one of most adopted solutions to
meet QoS requirements in 802.11 ad hoc networks. The
efficiency of these solutions depends to the accuracy of
their estimations of available bandwidth; otherwise, their
application can be catastrophic on networks. Therefore,
accurate bandwidth estimation is fundamental, where each
network characteristics must be taken into consideration,
including mobility and medium sharing in such networks.
Current solutions do not take into account all network
characteristics, resulting to wrong bandwidth estimations
and QoS violations. In this paper, we present a new
approach for bandwidth reservation -Accurate Bandwidth
Reservation (ABR)- that is embedded with a new available
bandwidth measurement method, where all criteria of such
networks are considered. Evaluation of ABR is performed by
simulations and comparisons with some existing
approaches.
