“…When a path is required the corresponding QoS parameter values associated with each path are calculated, and the path with the best value is chosen. The commonly used QoS parameters in early QoS routing protocols, such as QoS-AODV (Quality of Service AODV) and on-demand QoS routing (OQR) [5], are end-to-end delay and bandwidth. Other protocols, e.g., Reliable AODV and AODV Backup Routing [5], are designed to optimize packet delivery reliability in the presence of network dynamics, so they use packet delivery reliability, or loss ratio, as their QoS parameters.…”

Abstract-Security and quality of service (QoS) are two areas of mobile ad hoc network (MANET) research which have so far been largely carried out separately. Some of the unique characteristics of MANETs make them extremely vulnerable to security attacks, and these attacks have a direct impact on QoS provisioning. We therefore argue that integrating security and QoS may be the most effective way of providing QoS in MANETs that contain malicious nodes, and hypothesize that contextaware adaptive multi-path routing may mitigate the damaging effects of denial of availability (DoA) attacks, thus bettering QoS provisioning. As our first step towards validating this hypothesis, this paper investigates whether a single path should be sought using a reservation-based or a non-reservation-based approach.We compare INSIGNIA, a reservation-based approach to QoS in MANETs, with Dynamic Source Routing (DSR), a best-effort MANET routing protocol, using simulation. The performance of these two approaches is evaluated in the presence of a variable number of malicious nodes executing blackhole and grayhole data packet forwarding attacks and a denial of QoS attack. The simulation results show that INSIGNIA outperforms DSR when the traffic load is at a medium-to-high level and the threat level is at a low-to-medium level. This performance enhancement brought by INSIGNIA under these particular conditions is because of its single-path adaptation capability. These findings indicate that under certain conditions, e.g., when the network traffic level is low but the threat level is high, the single-path adaptation mechanism is no longer sufficient, and adaptive multipath routing may help to better QoS support.

“…If path gets failed while data packet transmission, source node repairs path or restarts the route selection procedure towards destination which results in control packet overhead in network and leads bandwidth wastage [2]. Along with this many other challenging factors and problems such as Chanel Capacity Constraints, Unpredictable Channel Access Delay, Inaccurate Bandwidth Estimation, and Network Heterogeneity are available for providing QOS in MANET [3][4][5][6][7][8][9]. To address such challenges number of design philosophy and routing protocols are available.…”

“…To address such challenges number of design philosophy and routing protocols are available. Based on how the information is acquired and maintained, MANET's routing protocols are categorized in to proactive, reactive, and hybrid [3]. Brief information about these categories is given in the following paragraphs.…”

Mobile Ad hoc Networks (MANETs) are used for providing Quality of Service (QoS) where nodes are having mobility and can travel in any random direction. There are several reactive protocols (DSDV, AODV, EBAODV, etc.) available in literatures which are suitable for MANETs based on single and multiple paths. Among these, AOMDV protocol is the most suitable for finding multiple paths to the destination. However, in its basic version does not consider mobility of intermediate nodes which causes packet loss in traveling. In this work to enhance the path stability, mobility of an intermediate node and exclude the selection of high mobility node is introduced. Mobility of nodes is calculated by using RREQ packet retransmission strategy. The intermediate results are stored in routing table and this information is forwarded to source node for path selection process. Finally, intermediate node having least mobility is selected by the source for data packet transmission towards destination. For this we used AOMDV protocol with three different mobility models (Random way point, Random Walk, and Gauss Markov). All the models are investigated using network simulator and their comparisons are presented and found satisfactory. General TermsMobile Ad hoc Networks, AOMDV, Routing.

“…In [6] OLSR enhanced by Multi-Constrained Path (MCP) QoS Routing, this method based on nonlinear cost function which is the combination of multiple additive QoS parameters, simulation demonstrates the important improvement over the standard protocol. Issues involved with QoS routing is studies in [7], then the authors presents an overview and comparison of existing QoS based revisions done on AODV protocol. In [8] the impact of scalability on three different Ad-hoc (Destination-Sequenced Distance Vector (DSDV), AODV and DSR) are analyzed, the result show that the performance of DSR decrease when the size of network increase and the overall performance of DSDV is less than AODV and DSR whereas AODV is QoS-aware routing protocol under the effect of scalability in terms of variation in number of nodes, mobility rate and packet intervals.…”

Simplified the QoS Factor for the Ad-Hoc Network Using Fuzzy Technique

Quality of Service (QoS) is a tool to measure the efficiency of the Ad-hoc network. QoS is a complex function because it depends mainly on four factors (throughput, packet delivery ratio, end-to-end delay and jitter). These four factors are functions of internal factors and are variables with the time. In the result the QoS is an ambiguous tool. This paper proposes a brand-new method to solve this ambiguity, it will use the fuzzy technique to simplify the QoS factor and summarize it in a simple form or in a single value for each application. So it will summarize all factors of the QoS in a single value for the network if the applications share is defined. This paper will apply the propose method on Mobile Ad-hoc NETwork (MANET) with different protocols. The new algorithm will summarize the efficiency of each protocol in a single (crisp) value for all applications. Finally, an important conclusion is proved, by experimental result, implying that higher throughput does not usually mean high QoS supported by the protocols.
