Adaptive Aggregation of Voice over IP in Wireless Mesh Networks
not my own work has been identified and no material is included for which a degree has previously been conferred. Abstract When using Voice over IP (VoIP) in Wireless Mesh Networks the overhead induced by the IEEE 802.11 PHY and MAC layer accounts for more than 80% of the channel utilization time, while the actual payload only uses 20% of the time. As a consequence, the Voice over IP capacity i...
متن کاملCapacity Increase for Voice over IP Traffic through Packet Aggregation in Wireless Mesh Networks
Recently, Voice over IP (VoIP) has become an important service for the future internet. However, for ubiquitous wireless VoIP services, greater coverage will be necessary as promised by the advent of e.g. 802.11 WLAN based wireless meshed networks. Unfortunately, the transmission of small (voice) packets imposes high overhead which leads to low capacity for VoIP over 802.11 based multihop meshe...
متن کاملScalable video transport over wireless IP networks
Recently, there has been great interest in transporting real-time video over wireless IP networks from both industry and academia. Real-time video applications have quality-of-service (QoS) requirements. However, fluctuations of wireless channel conditions pose many challenges t o provide QoS for video transmission over wireless I P networks. It has been shown that scalable video coding and ada...
متن کاملCross-Layer Optimization of Voice over IP in Wireless Mesh Networks
Optimizing the operation of IEEE 802.11 networks requires estimatingthe load of the wireless channel. The channel busy fraction, which is thefraction of time in which the wireless channel is sensed busy due to suc-cessful or unsuccessful transmissions, can be used as indicator for this pur-pose. It can be obtained from e.g. the IEEE 802.11k channel load reportor hardware-spe...
متن کاملRural Telemedicine Networks Using Store-and-Forward Voice-over-IP
Store and forward Voice-over-IP is a suggested solution for supporting Telemedicine at rural health clinics in developing countries. Solutions described to date are designed to support communication by establishing point-to-point connectivity between two sites. In this paper we present an approach for creating scalable Telemedicine networks based on Delay Tolerant Networking. This holds potenti...
