Performance evaluation of energy consumption for AODV and DSR routing protocols in MANET

Abstract: Proposing energy efficient routing protocols for Mobile Ad hoc Network (MANET) and Wireless Sensor Network is an uphill and challenging task. Many different routing protocols based on different features have been proposed to the IETF. Performances of many of these routing protocols have been evaluated focusing on metrics such as delay, routing overhead, and packet delivery. However, no studies have been done to investigate energy aspect of these routing protocols. Thus, this paper will discuss about the power consumption aspect of the MANET routing protocols. A performance comparison of Dynamic Source Routing (DSR) and Ad hoc On-Demand Distance Vector (AODV) routing protocols with respect to average energy consumption and routing energy consumption are explained thoroughly. Then, an evaluation of how the varying metrics in diverse scenarios affect the power consumption in these two protocols is discussed. A detailed simulation model using Network Simulator 2 (NS2) with different mobility and traffic models are used to study their energy consumption. Finally, an evaluation of these routing protocols based on energy consumption is presented.

Comprehensive Evaluation of AODV, DSR, GRP, OLSR and TORA Routing Protocols with varying number of nodes and traffic applications over MANETs

Abstract: Wireless Technology is at its peak when we talk about research and innovation. This field has become a hub of invention of new theories and structures. Mobile Ad-hoc Network is a special point of focus for the researchers. MANET is a collection of wireless mobile nodes which forms a dynamic temporary network without using any existing infrastructure. In recent time the market of mobile devices, laptops, hand held and portable devices is at its zenith so communication between such devices is an important issue. Routing is an essential part in the success of communication among these mobile structures. Routing protocols play an important role for finding an efficient and reliable route from source to destination. In the literature, there are numerous MANET routing protocols aiming to find the most suitable path from source to destination. In this paper, a comprehensive simulation based performance study and analysis is performed on various types of routing protocols over MANET. Ad Hoc On-Demand Distance Vector (AODV), Dynamic Source Routing (DSR), Temporally-Ordered Routing Algorithm (TORA), Optimized Link State Routing (OLSR) and Geographic Routing Protocol (GRP) has been considered for investigation in this paper based on OPNET simulation. Moreover the performance of these routing protocols will be measured on the basis of throughput, delay, load and data dropped metrics.

Performance Comparison of AODV and DSR Routing Protocols in Mobile Ad- hoc Networks:

Abstract: A mobile Ad-Hoc network is a collection of autonomous wireless nodes without any fixed infrastructure and centralized administration. This paper presents a survey with an objective to compare Ad-Hoc routing protocols AODV and DSR taking into consideration different network parameters performed using simulation, emulation and real world experiments. Various researchers over time have analyzed the performance of AODV and DSR routing protocols based on the different test parameter and environment. AODV and DSR have been mostly studied through simulation, while fewer implementations of these protocols have been done on real network test-bed. The objective of this survey is to review the AODV and DSR protocols based on the performance metrics such as mobility pattern, packet delivery ratio, average end to end delay, throughput, packet drop, node density and in different test environments.

A hybrid intrusion detection system based on different machine learning algorithms

Abstract: Recently, Networks have developed quickly during the last many years, and attacks on network infrastructure presently are main threats against network and information security.With quickly growing unauthorized activities in network Intrusion Detection as a part of defense is extremely necessary because traditional firewall techniques cannot provide complete protection against intrusion. There are numerous study in intrusion detection system (IDS) especially with Genetic algorithms (GA) and Support Vector Machine (SVM) but most of them did not get the potential of hybrid SVM using GA. Hence this study aims to hybrid GA and forbids with high accuracy.The paper illustrates the benefit of hybrid SVM via GA also the paper has proven that by enhancing SVM with GA can reduce false alarms and mean square error (MSE) in detecting intrusion.

An Energy Consumption Evaluation of Reactive and Proactive Routing Protocols in Mobile Ad-Hoc Network

Abstract: In Mobile Ad-hoc NETwork (MANET) each node has the possibility to move freely in the space and communicate with each other over wireless link without any centralized controller or base station These characteristics makes MANET useful and practical in several fields like military scenarios, sensor networks, Rescue operations, students on campus, etc but this kind of network still suffers from a number of problems, power consumption is one of the most crucial design concerns in Mobile Ad-hoc networks as the nodes in MANET have battery limited In this paper, we will discuss about the aspect of energy consumption in MANET's routing protocols A performance comparison of four routing protocols Dynamic Source Routing (DSR), Ad hoc On-Demand Distance Vector (AODV), Destination-Sequenced Distance Vector (DSDV) and Optimized Link State Routing (OLSR) with respect to average energy consumption are explained thoroughly Then, an evaluation of how the varying parameters of network in diverse scenarios affect the power consumption in these four protocols is discussed A detailed simulation model using Network Simulator 2 (NS2) with different mobility and traffic models is used to study their energy consumption

Performance Comparison of Routing Protocols

Abstract: A mobile ad hoc network (MANET) is a collection of wireless mobile nodes dynamically forming a network topology without the use of any existing network infrastructure or centralized administration. MANET is a self configuring network and the topology of the network keeps on changing as the nodes move randomly and organize themselves in an arbitrarily manner. Mobile nodes communicate with each other using multihop wireless links. Each node in the network also acts as a router, forwarding data packets for other nodes. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. Due to higher mobility in nodes and dynamic infrastructure of MANETs, Routing is important issue in ad hoc networks. ‗In this paper three routing protocols AODV (Ad- Hoc on-Demand Distance Vector), DSDV (Destination Sequenced Distance-Vector) and DSR (Dynamic Source Routing) are compared'. The metrics used for performance analysis are Packet Delivery Ratio, Average end-to-end Delay & Number of Packets Dropped.
