Research on Quality of Service Based Routing Protocols for Mobile Ad Hoc Networks

Quality of service (QoS) based routing protocols play a significant role in MANETs to maintain proper flow of data with efficient power consumption and without data loss. However, several network resource based technical challenges or issues are encountered in the design and implementation of QoS routing protocols that perform their routing function by considering the shortest route or the lowest cost. Furthermore, a secondary route is not reserved and alternative routes are not searched unless the established route is broken. The current structures of the state-of-the-art protocols for MANETs are not appropriate for today's high bandwidth and mobility requirements. Therefore, research on new routing protocols is needed, considering energy level, coverage, location, speed, movement, and link stability instead of only shortest path and lowest cost. This paper summarizes the main characteristics of QoS-based routing protocols to facilitate researchers to design and select QoS-based routing protocols. In this study, a wide range of protocols with their characteristics were classified according to QoS routing strategy, routing information update mechanism, interaction between network and MAC layer, QoS constraints, QoS guarantee type and number of discovered routes. In addition, the protocols were compared in terms of properties, design features, challenges and QoS metrics

An Optimised and Efficient Routing Protocol Application for IoV: A Review

Mobile ad hoc network (MANET) is a wireless network without a centralised administrator, where each node acts as a router forwarding data packets to other nodes. The study compares the performance of three routing protocols (AODV, OLSR, and DSDV) using the NS2 simulator under various mobility models. The proposed work introduces a modified protocol, MAODV, which combines the features of AODV protocols to optimise energy consumption, minimise transmissions, and find an optimum path for data transmission. The proposed method is compared with the standard AODV protocol. It shows better average throughput and packet delivery ratio results in a vehicular ad hoc network (VANET) scenario

Multicast Conventions to Improve Obstacle Detection and Collusion Avoidance in MANET

As of late, it got to be obvious that gathering focused administrations are one of the essential application classes focused by MANETs. In spite of the fact that these conventions perform well under particular versatility situations, movement loads, and system conditions, no single convention has been appeared to be ideal in all situations. The objective of this paper is to describe the execution of multicast conventions over an extensive variety of MANET situations. To this end, we assess the execution of lattice and tree-based multicast steering plans in respect to flooding and prescribe conventions most reasonable for particular MANET situations. In view of the investigation and reproduction results, we likewise propose two varieties of flooding, Perused flooding and hyper flooding, as a way to diminish overhead and expansion unwavering quality, separately. Another commitment of the paper is a recreation based relative investigation of the proposed flooding varieties against plain flooding, work, and tree-based MANET directing. In this paper we researched about various sending technique for GPSR in remote system furthermore discover the issues and their answers. The principle point of our study was to distinguish which directing strategy has better execution in very versatile environment of VANET. In MANET, this depletion of vitality will be more because of its infrastructure less nature and versatility. Because of this, the topology get shifted. This may definitely influence the execution of steering convention furthermore influence the system lifetime. To address this issue another calculation has been created which uses the system parameters identifying with element nature of hubs viz. vitality channel rate, relative versatility estimation to foresee the hub lifetime and connection lifetime. At that point execute this calculation in the DYMO convention environment. This will expand the system lifetime and adaptability. Further enhance the execution, we have actualized another calculation by incorporating course lifetime expectation calculation alongside the molecule swarm enhancement (PSO) calculation

An Overview of Mobile Ad Hoc Networks for the Existing Protocols and Applications

Mobile Ad Hoc Network (MANET) is a collection of two or more devices or nodes or terminals with wireless communications and networking capability that communicate with each other without the aid of any centralized administrator also the wireless nodes that can dynamically form a network to exchange information without using any existing fixed network infrastructure. And it's an autonomous system in which mobile hosts connected by wireless links are free to be dynamically and some time act as routers at the same time, and we discuss in this paper the distinct characteristics of traditional wired networks, including network configuration may change at any time, there is no direction or limit the movement and so on, and thus needed a new optional path Agreement (Routing Protocol) to identify nodes for these actions communicate with each other path, An ideal choice way the agreement should not only be able to find the right path, and the Ad Hoc Network must be able to adapt to changing network of this type at any time. and we talk in details in this paper all the information of Mobile Ad Hoc Network which include the History of ad hoc, wireless ad hoc, wireless mobile approaches and types of mobile ad Hoc networks, and then we present more than 13 types of the routing Ad Hoc Networks protocols have been proposed. In this paper, the more representative of routing protocols, analysis of individual characteristics and advantages and disadvantages to collate and compare, and present the all applications or the Possible Service of Ad Hoc Networks.Comment: 24 Pages, JGraph-Hoc Journa

Supporting Protocols for Structuring and Intelligent Information Dissemination in Vehicular Ad Hoc Networks

The goal of this dissertation is the presentation of supporting protocols for structuring and intelligent data dissemination in vehicular ad hoc networks (VANETs). The protocols are intended to first introduce a structure in VANETs, and thus promote the spatial reuse of network resources. Segmenting a flat VANET in multiple cluster structures allows for more efficient use of the available bandwidth, which can effectively increase the capacity of the network. The cluster structures can also improve the scalability of the underlying communication protocols. The structuring and maintenance of the network introduces additional overhead. The aim is to provide a mechanism for creating stable cluster structures in VANETs, and to minimize this associated overhead. Further a hybrid overlay-based geocast protocol for VANETs is presented. The protocol utilizes a backbone overlay virtual infrastructure on top of the physical network to provide geocast support, which is crucial for intervehicle communications since many applications provide group-oriented and location-oriented services. The final contribution is a structureless information dissemination scheme which creates a layered view of road conditions with a diminishing resolution as the viewing distance increases. Namely, the scheme first provides a high-detail local view of a given vehicle\u27s neighbors and its immediate neighbors, which is further extended when information dissemination is employed. Each vehicle gets aggregated information for road conditions beyond this extended local view. The scheme allows for the preservation of unique reports within aggregated frames, such that safety critical notifications are kept in high detail, all for the benefit of the driver\u27s improved decision making during emergency scenarios

Performance evaluation of dynamic source routing protocol with variation in transmission power and speed

Mobile ad-hoc network (MANET) is a set of mobile wireless nodes (devices) which is not rely on a fixed infrastructure. In MANETs, each device is responsible for routing its data according to a specific routing protocol. The three most common MANET routing protocols are: dynamic source routing protocol (DSR), optimized link state routing protocol (OLSR), and ad-hoc on-demand distance vector (AODV). This paper proposes an efficient evaluation of DSR protocol by testing the MANETs routing protocol with variation in transmission power at different speeds. The performance analysis has been given using optimized network engineering tools (OPNET) modeler simulations and evaluated using metrics of average end to end delay and throughput. The results show that the throughput increases as the transmission power increases up to a certain value after which the throughput decreases, also the network work optimally at a certain transmission power which varied at different speed
