“…Their algorithm focussed on the admission control policies and is implementable only on infrastructure-oriented networks. Using the concept of lowest weight first, Varaprasad and Wahidabanu (2011) provided a solution for enhanced QoS to end users in MANETs. Their model provides high throughput and low delay based solution for guaranteed QoS to end users.…”

“…The plot for processing time with varying number of ground nodes and UAVs is shown in Figure 4. Four existing QoS approaches namely, proportional fairness (PF) (Sun et al, 2013), McLaughlin et al (2008, M |M + |1 (Wen et al, 2012), and Weighted Fairness Queue (WFQ) (Varaprasad and Wahidabanu, 2011) were used for comparison with the proposed approach. UAVs provide a relay support to existing ground ad hoc networks with provisioning of efficient data transmission and improved QoS.…”

Hybrid networks provide a vast range of applications in areas of military and civilian activities. One of the examples of hybrid network formations is unmanned aerial vehicles (UAVs) assisted ground ad hoc networks. Efficient coordination in these networks can resolve complex issues such as coverage, proper connectivity, scalability, and QoS. However, reliable data transmission with enhanced QoS is one of the key challenges in these types of hybrid ad hoc formations. In this paper, an efficient queue scheduling approach is proposed that allows improved QoS to end users. The proposed queue scheduling approach is developed in two parts. The first part utilises the Quaternion based Kalman Filter to find the appropriate locations for placement of each UAV. In the second part, satisfied importance analysis (SIA) is used to find the governing rules for the selection of appropriate queue for transmission. The effectiveness of the proposed model is demonstrated using simulations.

“…The bandwidth requirement for the multimedia applications with desired level of Quality of service is one of the major challenges for the future wireless networks generation. Multimedia applications require a greater amount of bandwidth (Varaprasad & Wahidabanu, 2011) therefore a large number of data packet flows require many nodes to participate in the transmission. Hence, communication overhead and delay latency increases.…”

Multimedia applications over Internet are rising day by day hence stringent requirements of bandwidth and delay is an important issue. This paper is focused on QoS aware routing which provides optimal routes as a function of parameters like bandwidth, delay, packet loss etc. Thea authors' approach involves estimation of node bandwidth, delay and link expiration time at every node. The link expiration time metric is also considered for efficient route discovery to determine forecasting of route stability in near future and hence reliable route is identified. Existing link failure strategy involves frequent route discoveries which incurs high routing overhead and increased end-to-end delay. In this paper, efficient link failure strategy is also incorporated by utilizing multiple alternate paths in case of link failure which is determined with the help of signal intensity level to provide prediction before link break up. Performance of proposed approach is analyzed through simulation and validated analytically. Results show that the authors' approach has been found outperforming to existing approaches.

“…Next generation wired and wireless networks are evolving to accommodate a variety of services, including voice, data and real-time or streaming video/audio. Different applications come with diverse Quality of Service requirements, in terms of data loss, delay and throughput [1][2][3]. The "bottleneck" in such networks is the wireless link, not only because wireless resources (bandwidth and power) are more scarce and expensive than their wired counterparts, but also because the overall system performance degrades markedly due to multipath fading and time-dispersive effects introduced by the wireless air interface.…”

In mobile ad hoc network (MANET) the devices are interconnected by wireless manner that are able to ubiquitously retrieve contents such as video and audio streams, still images, and scalar sensor data from the environment. MANET provides low power in hazardous environment where replacement of fault evaluation in the MANET is impossible. Hence, development of an energy efficient network is essential in MANET, where the cost of network depends on the energy consumption of each mobile node. Overutilization of energy by a mobile node cannot contribute to the utility or the network as a whole. Hence to optimize the utilization of energy at each node, we propose an energy efficient multipath routing protocol for MANET for enhancing QoS and QoE metrics (EMRP-QQ), which can eventually minimize the data loss and hence there liability of the mobile nodes and the overall network. In our proposed approach an energy efficient clustering is performed using particle swarm optimization (PSO), where all the nodes are clustered without any residual nodes left in the system. Using the appropriate selection of CH and SCH the overall networks overhead utilization is reduced and hence the QoS of the network is enhanced. The result obtained through NS-2 simulation shows that the proposed algorithm performs better than FQ-MP-OLSR approach in terms of reduced energy consumption of each node without affecting QoS and QoE metrics.
