Popularity of Mobile ad hoc network in research is  due to their ad hoc nature and effectiveness at the time of disaster management when no infrastructure support is available. Due to the limited transmission range of wireless network interfaces, multiple network hops may be needed for nodes to exchange data across the network. In such a network, each mobile node operates as a router, forwarding packets for other mobile nodes in the network that may not be within the direct reach. Routing protocols developed for wired networks such as the distance vector or link state protocols are inadequate here as they not only assume mostly fixed topology but also have high overheads. This has lead to several routing algorithms specifically targeted for ad hoc networks. In this paper, we include the MANET supported routing protocols and their performance analysis over different performance parameters such as packet delivery ratio, delay, throughput, control overhead and energy etc.

Mobile Ad Hoc Network (MANET) is a set of mobile nodes that communicate with each other to configure an immediate network without utilizing any of infrastructure, the centralized access point or centralized administration in multiple hop manner. There are a lot of routing protocols have been proposed in MANET which are different from each other in the performance and the mechanism. Therefore, the performance study of those protocols in different scenarios is needed. This paper presents the performance comparison between Dynamic Source Routing (DSR), Ad hoc on demand distance Vector Routing (AODV) as reactive routing protocols and Destination Sequenced Distance Vector (DSDV) as a proactive routing protocol to precisely determine which protocol is more effective. Network Simulator (NS) version 2.35 has used to simulate and evaluate the performance of these protocols in terms of the packet delivery ratio, average throughput, average end-to-end delay, and packet loss ratio with respect to the variable number of nodes.

Abstract Mobile Ad-hoc Networks (MANETs) has gained remarkable appreciation during the last decade because of its high flexibility. Due to high mobility and unpredictable topology changes, most of the existing routing protocols are unable to adapt to these changes and efficient route selection becomes a challenging task. The existing routing protocols incur high control overhead during route discovery process, tendency to select an unreliable route and high data packet loss during route maintenance. Therefore, this paper presents A Congestion-aware and Predictive Geo-casting Routing Mechanism (CPGR) for MANET that optimally utilize the constrained network resources and reliably detect high-quality links. CPGR exploits a multi-facet routing strategy that takes into consideration the congestion level, relatively higher signal strength, and hop-counts of neigh- boring nodes while making routing decisions. This strategy not only ensures data dissemination via high quality nodes but also balances out resource consumption among nodes while traversing through shorter paths. Demonstrated by simulation results in NS-2, CPGR achieves improved performance in terms of end-to-end delay, control overhead, and packet delivery ratio as compared to existing solutions.

A Mobile Ad hoc network (MANET) is a network consisting of a set of wireless mobile nodes, in which nodes can communicate with each other without centralized control or established infrastructure. To obtain a better understanding of AODV (Ad hoc On-Demand Distance Vector Routing Protocol) and OLSR (Optimized Link State Routing Protocol) routing protocols, different performances are simulated and analyzed using OPNET modeler 14.5 with the various performance metrics, such as PDR (Packet Delivery Ratio), end-to-end delay and routing overhead. Only effect of mobility is analyzed in the paper. As a conclusion, in mobility case, routing overhead is not greatly affected by mobility speed in AODV and OLSR, and the PDR of OLSR is decreased as the node speed increased, while AODV is not changed. As to delay, AODV is always higher than OLSR in both static and mobility cases.

The Mobile and ad hoc wireless network has a set of nodes and is a low power, wireless infrastructure less, self-organized and limited distance communicating network devices. The nodes are always changing their characteristics over time results into a different network topology. So, it is very difficult to predict the mobile ad hoc network performance. In this research paper we proposed comparative analysis and estimate the performance of network amongst the mobile nodes by reducing the control overhead. Main intention of the paper is to relate and estimate the performance of different network routing protocols under diverse mobility models. The routing protocols performance metrics are examined with varying node speed and node density of network amongst different mobile nodes. NS-3 is used as a network simulator with version 3.25 (NS-3.25) to carry out the research simulation results.

Mobile Ad Hoc

In Mobile Ad-hoc Network (MANET), portable devices like smartphones, or laptop PC can join together to make provisional networks without any infrastructure The objective of multicast or unicast protocols is to ensure an efficient route formation and flow control mechanism which is a very challenging issue for many group computing services in MANETs. MANETs can support several real-time applications like emergency rescue, and disaster relief operations which require minimum Quality of Service (QoS) to handle high traffic. Providing QoS for multimedia and group-oriented computing in MANETs becomes a real challenge due to the wireless medium and the mobility of operating nodes. Therefore, an investigation of routing protocols for one-to-many or many-to-many computing is important that supports acceptable QoS in MANETs. Numerous QoS metrics have been considered for the assessment like packet delivery ratio, latency, packet loss rate, control overhead, and throughput. By considering different network topologies and scenarios with different performance parameters, the primary goal of this study is to explore the challenges and factors for QoS services in MANET’s multicast communication. The outcomes of investigation can be used to design the future MANET protocol for multimedia applications. The performance results indicate that the increasing number of sending/receiving nodes may increase the overhead or latency of the network but capable of providing higher network throughput, carried out in NS-2. The results also indicate although MANETs can induce errors and packets are lost as part of the normal operating context, multicast AODV practice superior to the unicast protocol to various QoS in a wide range of scenarios with less overhead.

This paper considers mobile ad-hoc network (MANET) in which mobile nodes can reach the Internet via stationary gateway node. The gateway works as bridge between MANET and the Internet. Several studies show that location of the gateway inside network topology has a significant effect on overall network performance. Two different scenarios, with varying number of nodes and two gateway locations, have been considered under the assumption that all mobile nodes are connected to Internet through the same gateway. Simulation has been done using NS-2 software, producing a computer model of AODV and DSR routing protocols. Comparison of these routing protocols is performed in terms of Average (end-to-end) delay, Throughput, Normalized routing load and Packet delivery ratio metrics. Simulation results suggest that AODV routing protocol has better performance in both scenarios. In addition, the results suggest that location of gateway at the center gives better results compared to gateway positioned at the edge.

<p>A Mobile Ad-hoc Network (MANET) refers to a dynamic and wireless network, which can be designed without an existing infrastructure as every node serves as a router. A MANET is a self-configuring system of mobile nodes that are connected wirelessly. Every node serves as a sink, as well as a router to send packets. The movement of the nodes is not restricted as they can move in any direction, and they have the ability to get organized into a network. Due to their free and independent movement, they do not have a fixed position; they often change positions. In this study, the Dynamic Source Routing (DSR) and Ad-hoc On Multipath Demand Distance Vector (AOMDV) protocols are compared using Network Simulator NS2.35. DSR is a reactive gateway discovery algorithm whereby the connection of a MANET mobile device is established only on demand. Basically, AOMDV was specially tailored for ad-hoc networks that are highly dynamic to respond to link failures and breakages in the network. It ensures that the paths for destinations are sustained, and it defines the new routing information using destination serial numbers to ensure loop freedom always while avoiding problems. More so, it is a protocol that is based on a timer that can discover ways through which the mobile nodes respond to link breakages and change in topology. A comparison of protocols has been carried out individually and jointly with the aim of evaluating their performance. The performance is measured in terms of End-to-End Delay, Packet Delivery Ratio, Packet Loss Ratio, and Routing Overhead Ratio. The performance of the routing protocols was done using two scenarios; when there is a change in the simulation time and when there is a change in the number of nodes.</p>

Mobile Ad Hoc Network is the centralized communication system which is used for transferring information through a secured mode from one end to another end. However, there is an energy loss that has been noticed in MANET. In this work, an efficient energy based Link Failure State Neighbor Detection Effective Efficient Protocol (LFSNDEEP) is to enhance the energy efficiency of the mobile node, and optimal transmission ratio computes Data, Audio, and Video packets. The proposed research on LFSNDEEP protocol is compared to Effective Efficient Neighbor Detection Protocol (EENDP) and which assigns the channel utilization. In this technique, the hello packet exchanges transmit based height and wavelength of the transmitter with particular distance. The computation of channel utility factor is the best method at link failure without data loss. The vitality utilization mathematical model is illustrated to show the nodes of least consumption by the broad recreation of utilization. The results observed from the proposed scheme shows that the energy level is minimized regarding the packet that loss is improved efficiently. In further, there are two results which can be gained in comparing with EENDP; firstly, packet delivery ratio and throughput get increased. And secondly, the end to end delay is decreased.

This paper evaluates the performance of Reliable Multipath Dynamic Source Routing Protocol (RM-DSR) protocol with different network size compared to DSR protocol. RM-DSR developed in the mobile ad-hoc network to recover from the transient failure quickly and divert the data packets into a new route before the link is disconnected. The performance of RM-DSR protocol is tested in the Network Simulator (NS-2.34) under the random way point mobility model with varying number of mobile nodes. The network size parameter is used to investigate the robustness and the efficiency of RM-DSR protocol compared to DSR protocol. The network size affects the time of the route discovery process during the route establishment and the route maintenance process which could influence the overall performance of the routing protocol. The simulation results indicate that RM-DSR outperforms DSR in terms of the packet delivery ratio, routing overhead, end-to-end delay, normalized routing load and packet drop.
