In this paper we propose admission control and multipath routing algorithm for differentiated services (DiffServ) based networks (ACMRA). The basic DiffServ architecture lacks the admission control mechanism thus injecting more QoS sensitive traffic into the network can cause congestion at the core of the network. ACMRA combines the admission control with route finding phase and our routing protocol...
Wireless mesh networks (WMNs) have recently gained a lot of popularity due to their rapid deployment and instant communication capabilities. However, as a key technology for next-generation wireless networking, WMNs lack suitable routing metrics and protocol for new features. Currently, AODV is the routing protocol used in WMNs. This paper proposes an ants-in-mesh (AIM) routing protocol for wireless...
A Mobile Ad hoc NETwork (MANET) consists of a collection of mobile nodes. As MANETs are gaining popularity day-by-day, new developments in the area of real time and multimedia applications are rising as well. Such applications require Quality of Service (QoS) evolving in terms of the constraints such as bandwidth, end-to-end delay, jitter and energy. QoS provisioning for MANET can be achieved over...
Ad hoc networks are collection of mobile nodes which communicate using wireless media without any fixed infrastructure. Each mobile host acts both as a network router and an end point as packets are forwarded over multiple hops. Node mobility being the distinguishing feature of the mobile ad hoc network, makes routing an important challenge. Hence, Quality of Service (QoS) is not easily achieved in...
We propose a novel, energy-aware, routing protocol for quality-of-service (QoS) support in an infrastructure-less ad-hoc network. Our stability-based, QoS-capable ad-hoc on-demand distance vector (SQ-AODV) protocol is an enhancement of the well-known ad-hoc on-demand distance vector (AODV) protocol. Our protocol utilizes a cross-layer approach, in which information about residual node energy is used...
Providing high quality communications service among mobile wireless devices is basically a challenging task in wireless ad hoc networks. In this paper, we propose a route stability based multipath quality of service (QoS) routing (SMQR) protocol for mobile ad hoc networks (MANETs) to support throughput and delay sensitive real-time applications in MANETs. Reliability of QoS-aware path is improved...
In this paper an efficient on demand QoS based routing protocol is developed which considers end to end application requirement and energy efficiency together with the route discovery mechanism of DSR to set up QoS route. The proposed QoS aware protocol works as per the user request for a route. If a request comes for QoS route, based on some application requirement (available bandwidth, transmission...
