Modified route-maintenance in AODV Routing protocol using static nodes in realistic mobility model

Abstract: One of the popular wireless network architectures is Mobile Ad Hoc Network (MANET). It can be easily deployed in every environment, without any underlying backbone and infrastructure support. MANET is a wireless network that consists of nodes which are mobile in nature. Each node in the network acts as a router which provides the flexibility to the topology of the network. In this paper, an extended AODV routing protocol is proposed for Ad-hoc networks which typically suits to resolve the realistic model problems. This proposed protocol may improve the performance of regular AODV routing protocol. It has all the features of AODV routing protocol, as it follows all the steps of the route discovery algorithm of AODV routing protocol. The main difference arises when it comes to the route maintenance approach. We assume that the network is also consist of the static nodes, which helps to recover the path while route maintenance. An assumption reveals that it may increase the efficiency of regular AODV routing protocol in terms of the metrics: End-to-end delay, Packets dropped, Routing overhead.

CDRA: Cluster-based dynamic routing approach as a development of the AODV in vehicular ad-hoc networks

Abstract: Over the last few decades, the researchers have been fascinated towards vehicular networks. Vehicular ad-hoc network (VANET) is a highly dynamic wheeled network where the on road vehicles and road — side units considered as nodes to allow the wireless communication. Each node acts as the host in VANETs. Due to high dynamic nature of VANETs the mobility pattern and the network topologies change frequently, that make it differ from the other type of ad-hoc network The challenge of this research is a crucial designing for dynamic routing protocol in VANETs. This paper proposes a cluster-based approach for dynamic routing in VANETs. This new routing approach have an aim of increasing the overall network throughput, delivery ratio with less normalized routing load in comparison of AODV Extensive simulations are carried out in NS2 to appraise the efficiency of the proposed cluster-based routing approach.

A Review and Performance Analysis of Reactive and Proactive Routing Protocols on MANET

Abstract: MANET is a spontaneous system of mobile nodes where each node plays the role of router and mobile station. They can join or disconnect from the network any time and transfer packets in peer-to-peer mode or a multicast mode. Nodes are connected by way of wireless links and form a random topology graph. Network topology may change rapidly and erratically, so it can considerably affect packet routing in terms of network throughout, load and delay. Multiple hops can locate between diversity of node’s route as a consequence form the communication as expanded complexity. In this paper the performance of three well-known MANET routing protocols - Ad hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Optimized Link State Routing (OLSR) - has bees been investigated. Furthermore, all above mentioned protocols are compared based on three important performance metrics which are average end-to-end packet delay, network load as well as network throughput.

Performance analysis of aodv, olsr, grp and dsr routing protocols with database load in manet

Abstract: Wireless Technology has an enormous use these days and is still becoming popular from times immemorial . It is at its peak when we talk about research. This is because of the latest technological demands now days arising from Laptops , Wireless devices such as Wireless local area networks (WLANs) etc. Because ofast growing popularity day by day, it has le d wireless technology data rates higher and it has made its price cheaper, which is why wireless Technology is growing so fast. In this paper we have presented some most commonly used routing protocols in MANET and c ompared the performance of AODV, OLSR, GRP and DSR routing protocol by using OPNET simulator 14.5. The performance is e valuated under different parameters like Delay, Loa d, and Media access delay, Network Load, Retransmission and Throughput for Dat abase load.

Abstract—The Internet of Vehicles (IoVs) has become a vital research area in order to enhance passenger and road safety, increasing traffic efficiency and enhanced reliable connectivity. In this regard, for monitoring and controlling the communication between IoVs, routing protocols are deployed. Frequent changes that occur in the topology often leads to major challenges in IoVs, such as dynamic topology changes, shortest routing paths and also scalability. One of the best solutions for such challenges is “clustering”. This study focuses on IoVs’ stability and to create an efficient routing protocol in dynamic environment. In this context, we proposed a novel algorithm called Cluster-based enhanced AODV for IoVs (AODV-CD) to achieve stable and efficient clustering for simplifying routing and ensuring quality of service (QoS). Our proposed protocol enhances the overall network throughput and delivery ratio, with less routing load and less delay compared to AODV. Thus, extensive simulations are carried out in SUMO and NS2 for evaluating the efficiency of the AODV-CD that is superior to the classic AODV and other recent modified AODV algorithms.

Performance evaluation of secure routing in ad-hoc network environment

Abstract: We have considered the problem of incorporating security mechanisms in routing protocols for ad hoc networks. There have been various secure routing protocols proposed for the mobile ad hoc network. Secured Ad hoc On Demand Vector Routing (SAODV) protocol considered as one of the popular existing secure routing protocol which have used digital signature and hash chain techniques to secure Ad hoc On Demand Vector Routing (AODV) protocol. Most of these protocols were analyzed by two standard techniques: simulation and security analysis. We have used simulative approach for the performance comparisons between AODV and SAODV routing protocols using Glomosim simulator. The packet deliver fraction, average end-to-end delay, throughput and number of dropped packets metrics have been chosen for comparison. The results have shown that packet delivery fraction decreased in the case of SOADV. Routing overhead and throughput increased in case of SAODV. The simulation result have shown that network performance degrade when security counter measure are taken. Secure routing protocols available today (such as SAODV) still need further optimizations to minimize the processing overhead, delays and to maximize the routing throughputs.
