Survey and Performance Analysis of Routing Protocols in MANET

2014

A Mobile Ad-hoc Network (MANET) consists of several mobile wireless nodes. It is infrastructure-less, self organized and self configurable network in which the mobile nodes move arbitrarily. A routing protocol establishes correct and efficient route between mobile nodes and find the routes to facilitate communication within the network. Route should be discovered and maintained with minimum overhead and bandwidth consumption. Here topology based routing protocols, both proactive and reactive protocols have been considered for study. The performance of routing protocols (DSDV, AODV, OLSR, DSR, TORA, ZRP) is analyzed in terms of their packet delivery ratio, throughput, end-to-end delay, bandwidth, control overhead and energy consumption. We analyze the solution of routing in MANET and evaluate its performance using Network Simulator-2 (NS-2) under different network parameters.

Comparative study and performance analysis of Routing protocols for MANET

Abstract: Wireless communication between mobile users is becoming more popular than ever before. This is due to recent technological advances in laptop computers and wireless data communication devices, such as wireless modems and wireless LANs. This has lead to lower prices and higher data rates, which are the two main reasons why mobile computing continues to enjoy rapid growth. With current advances in technology, wireless networks are increasing in popularity. Wireless networks allow users the freedom to travel from one location to another without interruption of their computing services. However, wireless networks require the existence of a wired base station (BS) in order for the wireless user to send/receive messages. Ad-hoc networks, a subset of wireless networks, allow the formation of a wireless network without the need for a BS. All participating users in an Ad-hoc network agree to accept and forward messages, to and from each other. With this flexibility, wireless networks have the ability to form anywhere, at any time, as long as two or more wireless users are willing to communicate. This chapter will introduce the mobile ad hoc networking in general, provide background on the nature and problems of this type of networking and give an overview of the current state of research. Mobile networking is one of the most important technologies supporting pervasive computing. During the last decade, advances in both hardware and software techniques have resulted in mobile hosts and wireless networking common and miscellaneous. Generally there are two distinct approaches for enabling wireless mobile units to communicate with each other. Keywords: Mobile ad hoc networks (MANETS) , Quality of services (QoS) , AODV, ZRP, DSDV routing.

Comparison of Various Routing Protocols & Brief of MANET

An aim of this paper is to analyze the performance of traditional topology based protocols in mobile ad hoc networks. A Mobile Ad-hoc network (MANET) is a self-configuring infrastructure less network of mobile devices connected by radio links and has dynamic topology. MANETs consist of mobile nodes that can freely move in and out of the network at any instant. This ad-hoc topology may change with time as the nodes move or adjust their transmission and reception parameters. Routing is considered to be one of the major challenging tasks in MANET's due to this dynamic network topology and also due to the absence of a centralized control. In this paper comparison of various traditional routing protocols like DSDV (Destination Sequence Distance Vector), DSR (Dynamic Source Routing) and AODV (Ad-hoc On Demand Distance Vector) are summarized.

The wireless links in this network are highly error prone and can go down frequently due to mobility of nodes. Therefore, routing in MANET is a critical task due to highly dynamic environment. In recent years, several routing protocols for mobile ad hoc networks are DSR, AODV and DSDV. Efficient routing protocols will make MANET reliable. Mainly protocols are of three kind i.e. proactive, reactive and hybrid. But, we will discuss proactive and reactive protocols. This paper provides an overview of these protocols by presenting their characteristics, functionality, benefits and limitations and then makes their comparative analysis so to analyze their performance. The objective is to make observation about the working and performance metrics of these protocols. This paper presents the survey of routing protocols in MANET.

Comparative Study on Performance Evaluation of Routing Protocols in MANETs

A mobile ad hoc network (MANET) is a collection of wireless mobile nodes communicating with each other using multi-hop wireless links without any existing network infrastructure or centralized administration. Due to varying network topology the most common challenging factor in MANET is routing [1][2]. The purpose of this paper is to study, understand, analyze and to evaluate the performance between four mobile ad-hoc routing protocols: Ad-hoc On-demand Distance Vector (AODV), Destination sequenced distance vector (DSDV), Dynamic Source Routing (DSR) and Zone Routing Protocol (ZRP). DSR has the optimum performance in terms of mobility and speed in small scale networks but it loses its performance when the network size is increased. AODV is best suited when the load of the network is increased. ZRP is hybrid nature and comparable performance in average end-to-end delay and average throughput; but it is the worst performance in packet delivery ratio. This simulation results were analyzed by graphical manner and trace file based on different metrics; such as average throughput, packet delivery ratio (PDR) and average end to end delay.

Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile hosts forming a temporary network without the aid of any stand-alone infrastructure or centralized administration. Due to the mobility of the nodes in the network, these nodes are self-organizing and self-configuring. Not only they act as hosts, but also they function as routers. They direct data to or from other nodes in the network. In MANETs, routing protocols are necessary to find specific paths between the source and the destination. The primary goal of any ad-hoc network routing protocol is to meet the challenges of the dynamically changing topology. Therefore, an efficient route between any two nodes with minimum routing overhead and bandwidth consumption should be established. The design of these routing protocols is challenging due to the mobility and the dynamic nature of the mobile ad-hoc networks. MANET routing protocols are categorized into two types: proactive and reactive. In this paper, the MANET characteristics and challenges are highlighted. In addition, the previously mentioned categories of routing protocols, proactive and reactive, are explored. Moreover, a comparison is conducted between three protocols; namely, DSDV, DSR and AODV in terms of both properties and performance. Finally, a critical analysis is performed on some papers that discussed routing in MANET.

Comparative Evaluation of Mobile Ad Hoc Network (Manet) Protocols Routing

Wireless Ad Hoc networks are relatively new and are gaining ground in research due to promises they offer. Wireless Ad hoc networks do not require predefined configuration and have no fixed infrastructure. They are self-organizing and self-configuring networks. Several protocols have been developed that vary in the performance and complexity. Most routing protocols for mobile ad hoc networks, such as: Ad Hoc On Demand Distance Vector Protocol (AODV), Dynamic Source Routing (DSR) are designed without explicity considering quality of service of the generated route. These routing protocols provide the capability for establishing minimum hop paths between nodes on a best effort basis regardless of QoS. In our work, we analyze the performance of these protocols and we present an efficient scheme for support QoS over MANET named Hierarchical Dynamic Source Routing protocol (HDSR). The performance aspects we study are fraction of routing overhead, end-to-end delay and throughput. It was shown via computer simulations that (HDSR) improves these performance aspects in wireless mobile ad hoc networks compare to other protocols.

Performance Analysis of MANET Routing Protocols A Comparative Study

International Journal of Computer Applications, 2013

Ad Hoc Networks are multi -hop wireless networks with dynamically changing network connectivity owing to mobility. The protocol suite includes several routing protocols specifically designed for ad-hoc routing. The conventional routing protocols such as shortest-path routing algorithms are not particularly well suited for operation in ad-hoc networking environment. The most widely used ad hoc routing protocols are Ad-hoc On-Demand Distance Vector Routing (AODV), Destination Sequenced Distance Vector (DSDV), Dynamic Source Routing (DSR) and Temporally -Ordered Routing Algorithm (TORA). In this paper, the three random based mobility models such as Random waypoint, Random walk and Random Directions were implemented. The two different parameter constraints like packet-delivery fraction and End-toend packet delivery delay are compared with respect to mobility speed, Traffic and Network size. The simulation results shows that the AODV protocols in Random Waypoint mobility model performs better than DSDV, TORA and DSR in Random walk and random Direction mobility model. . Based on the observations, it is to suggest that AODV routing protocol can be used under high mobility since it outperforms DSDV, TORA and DSR protocols.

The mobile node communicates with each other without centralized control or existing infrastructure. Mobile nodes that are not within the direct transmission require intermediate nodes to transfer the data. Therefore, routing in mobile ad hoc network is a difficult one due to dynamic environment. This paper provides a survey of several routing protocols such as Optimized link state routing (OLSR), Dynamic source routing (DSR), Ad hoc on demand distance vector routing (AODV), Destination sequenced distance-vector routing (DSDV) and Proactive source routing protocol (PSR). This paper gives characteristics, functionality, benefits and limitations of these baseline routing protocols. The performance of these baseline protocols are analyzed by using various network parameters.
