In Ad-hoc networks, routing is complex as nodes are mobile due to which paths are destroyed and generated again and again. The difficulty in MANET is to find a feasible path between communicating nodes as routing is non-deterministic polynomial hard which is due to mobile nature of nodes. Many past works focused on finding a feasible path from a source to destination by considering only a single parameter...
Quality of Service (QoS) ensures the quality of the network. The proficiency of multiple path formula surmounts the problems of single path routing protocol while transferring the data. But the speedy outgrowth of real time application considers the QoS requirement such as packet delivery ratio, end to end delay, throughput and residual energy. The proposed routing technique ensure that it contributes...
Mobile Ad hoc network (MANET) is a special type of network that supports connectivity without any infrastructure and it faces many challenges such as high mobility rate of the nodes, resource constraint and the nodes work without any central administration. In Mobile Adhoc Network (MANET), the mobile devices have restricted resources such as limited battery power, so it is difficult for traditional...
We present in this paper a multi-layer scheme for QoS Management in MANETs. Our proposal is to combine multiple communication protocols of different layers, to provide an adapted QoS to a different traffic classes. Protocols are modified to improve their awareness of the quality of service, so that new extensions with QoS support are developed. We model QoS service at routing layer, via a QoS extension...
A mobile ad hoc network (MANET) is a collection of wireless mobile nodes that can communicate without any centralized administration or fixed infrastructure. Because of limited wireless link capabilities, nodes with heavy traffic will reduce their energy rapidly and increases the possibility of congestion and path disconnection. Hence, load balancing and congestion is necessary in MANET. Thus, this...
The network topology in Mobile Ad hoc Networks (MANETs) dynamically changes due to mobility of nodes and power constrained, hence routing is a challenging issue in these networks. QoS aware routing is needed to provide optimal routes as a function of parameters like bandwidth, delay, packet loss etc. Our approach is focused on QoS enabled route discovery procedure which involves estimation of node...
Mobile ad hoc networks (MANETs) are spontaneously deployed over a geographically limited area without well-established infrastructure. In a distributed Mobile Ad Hoc Network (MANET), collaboration and cooperation is critical concern to managing trust. The networks work well only if the mobile nodes are trusty and behave cooperatively. Due to the openness in network topology and absence of a centralized...
In Mobile Ad Hoc Networks (MANET), delays and bandwidth limitations of the wireless network system adversely affect the performance of the Voice over IP (VoIP). The calls setup time and the voice Quality of service (QoS) of VoIP calls depend on the routing protocol, the mobility model, and the number of hops between the call parties. Number of research efforts used to study the performance metrics...
Most of the Future Internet users will be wirelessly connected to IP clouds through different types of wireless networks. Thus, the number of applications and devices will be increased, and IPv6 insists to be applied. Voice over IP (VoIP) is one of the most popular Internet applications which provide real time voice communications between different parties and network systems. The Quality of Service...
Mobile ad hoc network (MANET) is a multi-hop temporary autonomous system of mobile nodes with wireless transmitters and receivers without the aid of pre-established network infrastructure. With the development of network and demand of users, QoS has become one of the focus issues. A new routing protocol is proposed in this paper, which can provide QoS guarantee. In the route discovery phase, it finds...
The task of finding and sustaining routes in mobile ad-hoc networks (MANETS) is an important factor in determining the efficiency of any MANET protocol. MANET characteristically comprises of wireless mobile hosts whose communication with each other is devoid of any fixed infrastructure. Absence of fixed infrastructures and host mobility thus constitute frequent unpredictable topological views. Positional...
The presence of delay-sensitive traffic in QoS-aware MANETs (mobile ad-hoc networks) results into increased TCP spurious timeouts, thus wasting their scarce bandwidth. Furthermore, the different dynamics used by a routing protocol in discovering and maintaining routes have a significant impact on TCP and MANETs in general. In this paper, we investigate the combined effect of contention- induced spurious...
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...
