Quality of service (QoS) of ad hoc network has become a very important research issue in the wireless networks. The ability to adjust the allocated bandwidth of ongoing flows is becoming increasingly significant. In this paper, we describe a fuzzy price-based bandwidth controller for traffic provisioning in ad-hoc network. The transmission rate of source is fuzzily adjusted based on the accumulated...
The ability to adjust the allocated bandwidth of ongoing flows to cope with resource fluctuation of wireless network is becoming increasingly important. In this paper, we describe a price-based bandwidth adaptation scheme for quality-of-service (QoS) provisioning in ad-hoc network. Depending on the network load, the allocated bandwidth of flows is adjusted dynamically such that the QoS of the wireless...
Achieving effective voice communication over mobile ad hoc networks (MANETs) offers both new challenges and opportunities for speech coding. This paper investigates a new 13.6 kb/s subband structure bandwidth scalable (SB-SWS) scheme for MANETs, which is based on a high-quality narrowband speech coder, the 11.8 kb/s G.729 Annex E, with the higher band using a bandwidth extension (BWE) approach to...
