چکیده
In this paper, we propose an accurate method to evaluate the available bandwidth in IEEE 802.11-based ad hoc networks. We improve the method described in [12]. We evaluate our solution on different scenarios. We also provide a comparison with different QoS routing protocols, BRuIT, AAC and QoS-AODV, based on different available bandwidth estimation techniques.

Available Bandwidth Estimation and Prediction in Ad hoc Networks
Wireless ad hoc networks provide quick and easy networking in circumstances that require temporary network services or when cabling is difficult. With the widespread use of multimedia applications that require Quality of Service (QoS) guarantees, research in providing QoS support in wireless ad hoc networks has received much attention recently (Nafaa, 2007). The term QoS gathers several concept...
متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...
