In this paper, a routing protocol with (end-to-end) QoS support is proposed by giving routing access to bandwidth information. Topology-transparent scheduling (TTS) is chosen as the medium access control (MAC) in both the control and data channels. Based on the information collected in the control channel, bandwidth estimation and reservation at individual nodes are developed to efficiently utilize...
In the recent years, multipath routing techniques are recognized as an effective approach to improve QoS in Wireless Sensor Networks (WSNs). However, in most of the previously proposed protocols either the effects of inter-path interference are ignored, or establishing low-interference paths is very costly. In this paper, we propose a Low-Interference Energy-efficient Multipath ROuting protocol (LIEMRO)...
Anycast is a new service of IPv6. How to guarantee its quality of service(QoS) has become an important subject. An anycast QoS routing algorithm supporting traffic engineering(ART) in multi-protocol label switching(MPLS) networks is proposed. In order to select a QoS path for client's bandwidth request, information regarding the source-destination pairs is used to reduce the interference between current...
Recently, because of the rising popularity of multimedia applications and potential commercial usage of MANET(Mobile Ad Hoc Network)s, and the limited bandwidth and dynamic topology in MANETs. providing required bandwidth for these applications in MANETs has become an unavoidable and urgent task to achieve sufficient QoS (Quality of Service). Time slot assignment is essential to provide the calculated...
Wireless interference can make a significant impact on the performance of a wireless network. The paper studies TDMA-based timeslot allocation to schedule links efficiently under RTS/CTS interference model of wireless networks, and presents an efficient distributed timeslot assignment algorithm. In addition, the paper presents an effective heuristic algorithm for calculating end-to-end bandwidth on...
