“…While FIFO queueing might be exceedingly predominant in wired system foundations today, restricting data transmission estimation to such systems does not completely misuse the capability of system testing procedures. This propels the production of another establishment for data transfer capacity estimation for system situations, where FIFO suppositions are hard to legitimize, for example, remote or multi-get to systems [7].…”

Majority of the wireless ad hoc routing protocols are proposed to find feasible routes without considering the network load, end-to-end link quality and bandwidth requirements of the application. Therefore, protocol may not provide sufficient quality of service (QoS) to a high speed traffic such as multimedia. In this paper, we propose a path-quality and bandwidth-estimation based routing protocol (PBBR) for the high quality multimedia stream that can meet the application's bandwidth requirements and find the best reliable route. The novelty of this protocol is to select a reliable path to respond the application's requirements based on available bandwidth at each intermediate node and end-to-end path loss ratio. Obtained results from the simulation demonstrates that our protocol can achieve sufficient performance in terms of throughput and end-to-end delay.Key Words : Ad hoc network, Bandwidth, MANET, QoS, Video Stream. Ⅰ. IntroductionThe rapid advancement of wireless technology has gained much attention to the research community for high quality multimedia applications such as video telephony, video games, voice over IP, and emergency rescue systems [1] . Performance of some real world test-bed have persuaded the researcher to investigate There are few routing protocols in the literature that considered available bandwidth estimation to provide QoS [6] [7] . However, they did not consider the end-to-end path quality such as end-to-end path loss ratio which is essential to provide sufficient QoS. This motivates us to design the path-quality and bandwidth-estimation based routing protocol (PBBR).In our protocol, total consumed bandwidth is estimated at each node and disseminates the information to the neighbors through periodic "Hello" message. Each host estimates the available bandwidth using the neighbor's overall consumed bandwidth information and updates periodically. End-to- II. Path-quality and Bandwidthestimation Routing ProtocolQuality of service (QoS) is a overall performance of a network such as required bandwidth, packet delivery ratio and delay constraints to the applications. We consider the required bandwidth constraints and end-to-end path loss ratio for supporting the QoS of real time multimedia transmission.We propose PBBR protocol that satisfy the required bandwidth and best available route termed as 'reliable route' in the network. We focus on estimating the available bandwidth at each node, integrating PBBR scheme into the route discovery process.

WLAN devices based on CSMA/CA access schemes have become a fundamental component of network deployments. In such wireless scenarios, traditional networking applications, tools, and protocols, with their built-in measurement techniques, are usually run unchanged. However, their actual interaction with the dynamics of underlying wireless systems is not yet fully understood. A relevant example of such built-in techniques is bandwidth measurement. When considering WLAN environments, various preliminary studies have shown that the application of results obtained in wired setups is not straightforward. Indeed, the contention for medium sharing among multiple users inherent to CSMA/CA access schemes has remarkable consequences on the behavior of and results obtained by bandwidth measurement techniques. In this paper, we focus on evaluating the effect of CSMA/CA-based contention on active bandwidth measurement techniques. As a result, it presents the rate response curve in steady state of a system with both FIFO and CSMA/CA-based contending cross-traffic. We also find out that the distribution of access delay shows a transient regime before reaching a stationary state. The duration of such transient regime is characterized and bounded. We also show how dispersion-based measurements that use a short number of probing packets are biased measurements of the achievable throughput, the origin of this bias lying on the transient detected in the access delay of probing packets. Overall, the results presented in this paper have several consequences that are expected to influence the design of
