Mobile Ad Hoc Networks: An Overview (original) (raw)

Review of Various Routing Protocols in Mobile Ad-Hoc Networks (MANETs

Mobile Ad-hoc Network (MANET) is a wireless network and is a collection of independent mobile nodes which dynamically forms a temporary network. Nodes of a MANET move without any fixed infrastructure and do not have a centralized administration mechanism. These nodes know the self-aware architecture of MANET and can move in any direction, which render its topology. The wireless connections in this system are highly sensitive and can go down because of limited energy, portability of nodes, obstructions and less foundation. Consequently, routing in MANET is the most challenging issue due to the dynamic topology of ad hoc networks. There are different routing protocols proposed for MANETs which makes it quite difficult to determine which protocol is suitable for different network conditions as proposed by their Quality of service offerings. This paper provides an overview of different routing protocols proposed in literature and also provides a comparison between them Due to moving element nature Mobile Ad-hoc wireless networks are used in Military scenarios, Sensor Networks, Rescue operations etc.

A State-of-The-Art of Routing Protocols for Mobile Ad-Hoc Networks (MANET)

International Journal of Computer Applications, 2015

Mobile Ad Hoc network (MANET) is a collection of two or more devices, nodes or terminals with wireless communication and networking ability that can communicate with each other without the assistance of any centralized administrator, centralized control or established infrastructure. It's called infrastructureless. A network can be formed dynamically by the wireless nodes to exchange information without using any fixed existing network infrastructure. Each node plays a role of router in the MANET as it must forward the traffic to other nodes. In this paper, discuss in details the main characteristics, applications, advantages, disadvantages and challenges of Mobile Ad Hoc Networks. Several routing protocols have recently been proposed for Mobile Ad Hoc Networks, In order to facilitate communication within the network, a routing protocol is used to discover route between nodes. On other hand, also this paper provides a survey of the type of routing protocols. These protocols can be classified into three main categories: proactive(Table-Driven), Reactive (On-Demand),and Hybrid Routing Protocols.

International Journal of Advanced Research in Computer Science, 2017

The expansion in accessibility and popularity of versatile wireless mobile devices have lead scientists to build up a wide range of Mobile Ad-hoc Network (MANET) Protocols. Mobile ad-hoc networks (MANETs) are a subclass of wireless ad-hoc network having extraordinary qualities of dynamic network topology and moving nodes. Mobile ad-hoc networks (MANETs) are foundation less self arranging systems intended to support portability. Mobile Ad Hoc Network (MANET) is accumulation of multi-bounce wireless portable nodes that speak with each other without incorporated control or set up framework. The wireless connections in this system are highly sensitive and can go down much of the time because of portability of nodes, obstruction and less foundation. Consequently, routing in MANET is a basic assignment because of dynamic environment.

Performance Analysis of Routing Protocols in Mobile AD-HOC Networks (MANETs)

IOSR Journal of Computer Engineering, 2014

A mobile ad-hoc network (MANET) is a self starting dynamic network comprising of mobile nodes, where each and every participation node voluntarily transmit the packets destined to some remote node using wireless (radio signal) transmission. The main aim behind the developing of ad hoc networking is multi-hop relaying. Wireless Ad hoc networks or infrastructure less networks are very easy to establish by using radio waves as transmitting medium without the requirements of any other equipment or infrastructure. An ad hoc network doesn't have any centralized arbitrator or server. In MANET, all networking functions such as routing and packet forwarding, are performed by nodes themselves in a self-organizing manner. For these reasons, securing a mobile ad-hoc network is very challenging in many areas such as routing, bandwidth, security, power consumption, collisions, simulations, and topology control due to moving nodes. This paper provides an overview of AODV, DSR, and TORA. The comparisons among three routing protocols are based on the various protocol property parameters such as Route Discovery, Network Overhead, Periodic Broadcast, Node overhead etc. different routing protocols proposed in literature and also provide a comparison between them.

A comparative study of MANET routing protocols

The Third International Conference on e-Technologies and Networks for Development (ICeND2014), 2014

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.

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.

A Review on Routing Protocol in MANET

IJSRD, 2014

A Mobile Ad-Hoc Network (MANET) is a self-configuring network and the nodes are connected through wireless link. It is an infrastructure less network. The wireless network topology may change rapidly. Each node in the network act as router and it communicate other nodes. There is no centralized administration. Nodes in ad hoc networks are differentiated by their limited resources like power, memory and mobility. Due to the limited transmission range of the nodes, multiple hops may be needed for a node to send data to any other node in the network. Thus each node acts as a host and router. If a node needs to communicate with another that is outside its transmission range, an intermediate node acts as a router to relay or forward packets from the source to the destination. For this purpose, a routing protocol is needed. This paper presents a survey on various routing protocols.

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.
