This paper proposes a solution for throughput and stringent delay problems of VoIP in Ad-Hoc mode of IEEE 802.11 WLAN standards. This paper analyses the behaviour different codecs and schemes of WLAN running on VoIP traffic and draws a conclusion on the performance of network based on the criteria of different QOS parameters. Later the suitability of different routing protocols like AODV, DSR, OLSR...
IEEE 802.11 protocol has found wide acceptability in the past few years, especially in embedded devices. Some of the embedded devices supporting 802.11 interfaces are voice and video-based devices like cordless phones, music players, camcorders, etc. These devices work in ad-hoc mode of operation for a number of applications. Such applications have some mandatory requirements that require one to determine...
Congestion bottlenecks at nodes where flows cross can severely limit the number of simultaneous flows in ad hoc wireless networks using 802.11 media access. We show how routing protocols and packet generation parameters can be modified to reduce congestion at such bottlenecks. We also present results of implementation tests which show dramatic reduction of packet error rate and delay, and increase...
