Analisis Pengaruh Metode LET Pada Protokol Routing Proaktif dan Reaktif Pada Jaringan MANET

Destination-Sequenced Distance Vector Protocol (DSDV) is a proactive protocols available in Ad-Hoc mobile network where this protocol is not suitable for use on networks with high mobility because DSDV needs to update routing tables regularly if there is a link between nodes that is disconnected because there are nodes that move out of the transmission signal range and the AODV protocol is a protocol that matches high mobility because it is reactive. So that in a stable route search can be done by selecting a route that has a small chance of being interrupted. LET algorithm is used in the DSDV protocol to find the most stable route by knowing the estimated time between two nodes to remain connected based on the position, speed and range of the transmission signal then compared with the AODV routing protocol based on parameters such as throughput, packet delivery ratio and delay. The results showed that the S-DSDV routing protocol has better performance than the standard DSDV routing protocol.

A Relative Study of Various Routing Protocols in Mobile Ad Hoc Network

Mobile Ad hoc Network (MANET) is an infrastructure fewer networks built on a multihop conveying idea. It transmits data from base node to end node. Because MANETS don’t have any fixed infrastructure and it works in a distributed manner. For efficient communication, many routing protocols are used in MANET. Routing protocols are to find a new route to transmit data from base to accurate end through the midway nodes. Every in-between node is act as a router. So, this paper is covers the routing protocols AODV, DSR, DSDV and OLSR to keep current routing information from every node to each other nodes. The purpose of this paper to offers a relative study of routing protocols in MANET and energy aware performance metrics are analyzed on two routing protocols of AODV and DSDV.

Comparative Analysis of Clustering using AODV DSDV and CBRP

In a network whether wireless or wired, a set of protocols which are used to distribute the information through various routes between the nodes are said to be the routing protocols which serves as a majorly vital part of the computer networks. They specify the particular and specific path of information exchange by the sending and receiving of packets. Vehicular ad- hoc networks are quite emerging technologies of today’s era presenting the provision of seamless and uninterrupted communication in the network of mobile nodes in dynamic environment. Routing itself proves to be quite a considerable and crucial challenge where the routing protocol named AODV performs its best by proving itself considerably more efficient. The stated paper focuses on the Performance comparison of the conventional protocols AODV and DSDV where AODV outperforms DSDV and offers better QoS but such conventional protocol proves to be inauspicious in VANET. This paper gives verification of better QoS of cluster based routing protocol CBR over the conventional routing protocols. The Simulation and comparison results have been carried out in Network Simulator NS-2 to briefly elaborate the impact of AODV DSDV and CBR routing protocols on the bases of Throughput, Normalized Routing Load, Control overheads, delay, Jitter and Packet drop ratio as performance metrics.

A Clustering-Based Fast and Stable Routing Protocol for Vehicular Ad Hoc Networks

For the sake of improving network performances, i.e. end-to-end delay and packet drop ratio (PDR), in vehicular ad hoc networks (VANET), we propose a clustering-based fast and stable routing (CFSR) protocol. The CFSR protocol introduces a link quality assessment mechanism that evaluates the link quality on road segments between intersections and adopts the end-to-end delay as an evaluation metrics to assign a weight to the link corresponding to each road segment. The delay-sensitive application can directly use this weight as the link quality indicator to directly establish the routing path in the sub-zone by using Dijkstra algorithm. At the same time, the concept of local coordinator (LC) is introduced into the routing protocol to help construct the routing path conveniently and quickly. In addition, it can also avoid the local optimum problem caused by single-step decision and reduce the network transmission delay. In this paper, the Simulation of Urban Mobility (SUMO) and Network Simulation 3 (NS3) are used to simulate this protocol. Simulation results reveal that CFSR protocol can obtain lower end-to-end delay and PDR than those of the AODV and DSDV protocols.

Equal And Unequal Distribution of Nodes based Simulation of Routing Protocols in MANET

One important aspect of mobile ad-hoc networks is the group mobility of nodes in topological area, since any node can enter or leave the topological area at any time. The resources are limited with mobile ad-hoc networks, so increasing number of node cannot generate more resources, but they can use and share existing resources with pre-existing nodes in the topological area. An important aspect of group mobility is mobility of nodes inside the group with reference to their leader. Inthis paper we analyze the two protocols AODV and DSDV with equal and unequal distribution of nodes in group.

Quantitative Comparative Study of Selected Routing Protocols in MANET based on Security

Mobile ad-hoc network (MANET) is a sub class of ad-hoc network and it dynamically forms a temporary network without any support of central administration. Ad hoc network is a collection of wireless mobile nodes without any fixed infrastructure. The network is ad hoc because it does not rely on any pre-existing network infrastructure like routers in wired networks. Such networks have no fixed topology due to the high degree of node mobility. Node mobility may cause the routes change. Hence, routing in MANET is a critical task due to its highly dynamic environment. To accomplish this task, a variety of routing algorithms have been proposed and also the number remains increasing day by day. These protocols fall in to mainly three categories---Proactive, Reactive and Hybrid. But, it is difficult to determine which protocol performs best under a number of different scenarios. This paper presents the qualitative comparison of selected proactive routing protocols DSDV, OLSR and CGSR based on security. General Terms MANET Protocols, Comparative Study

Performance Analysis of AODV and DSDV Routing Protocol in MANET and Modifications in AODV against Black Hole Attack

MANET stands for Mobile ad hoc network and is an infrastructure-less network and it is having ability to configure itself. The topology of network changes dynamically. It consists of wireless mobile nodes which communicate with each other without any centralized administration. In MANET different types of routing protocols are introduced. These protocols can be categorized into reactive, proactive and hybrid routing protocols. In this paper, AODV and DSDV protocols are analyzed in terms of routing overhead, packet delivery ratio, throughput and end to end delay. The performance of AODV is better than DSDV in terms of throughput, packet delivery ratio and routing overhead. As the DSDV is a proactive routing protocol, it is having a less end to end delay as compare to AODV. The performance of AODV gets affected by black hole attack. This paper gives the modification in AODV which helps to improve the performance of AODV in presence of black hole attack.

Communication Framework for Jointly Addressing Issues of Routing Overhead and Energy Drainage in MANET

The advancement into smart mobile devices has accelerated the adoption of various pervasive computing based ubiquitous applications, where Mobile Adhoc Network (MANET) has extended its usability from hard core military applications to civil society applications. The success for routing requires a robust computational mechanism of routing based on the collaborative framework of energy (i.e. battery power), signal strength and zonal routings. The paper presents a framework of novel routing technique in order to jointly address the problem pertaining to routing overhead and energy drainage among the mobile nodes. Different from conventional simulation mechanism, the paper presents a communication district with inclusion of auxiliary nodes for minimizing the overhead during the routing process. The outcome of the proposed study shows significant reduction in routing overhead along with energy efficiency as compared to existing AODV and DSDV protocols.
