A Review of the Energy Efficient and Secure Multicast Routing Protocols for Mobile Ad hoc Networks

This paper presents a thorough survey of recent work addressing energy efficient multicast routing protocols and secure multicast routing protocols in Mobile Ad hoc Networks (MANETs). There are so many issues and solutions which witness the need of energy management and security in ad hoc wireless networks. The objective of a multicast routing protocol for MANETs is to support the propagation of data from a sender to all the receivers of a multicast group while trying to use the available bandwidth efficiently in the presence of frequent topology changes. Multicasting can improve the efficiency of the wireless link when sending multiple copies of messages by exploiting the inherent broadcast property of wireless transmission. Secure multicast routing plays a significant role in MANETs. However, offering energy efficient and secure multicast routing is a difficult and challenging task. In recent years, various multicast routing protocols have been proposed for MANETs. These protocols have distinguishing features and use different mechanismsComment: 15 page

Review of multicast QoS routing protocols for mobile ad hoc networks

A Mobile Ad hoc NETwork (MANET) is consisting of a collection of wireless mobile nodes, which form a temporary network without relying on any existing infrastructure or centralized administration. Since the bandwidth of MANETs is limited and shared between the participating nodes in the network, it is important to efficiently utilize the network bandwidth. Multicasting can minimize the link bandwidth consumption and reduce the communication cost by sending the same data to multiple participants. Multicast service is critical for applications that need collaboration of team of users. Multicasting in MANETs becomes a hot research area due to the increasing popularity of group communication applications such as video conferencing and interactive television. Recently, multimedia and group-oriented computing gains more popularity for users of ad hoc networks. So, effective Quality of Service (QoS) multicasting protocol plays significant role in MANETs. In this paper, we are presenting an overview of set of the most recent QoS multicast routing protocols that have been proposed in order to provide the researchers with a clear view of what has been done in this field

Xcast Based Routing Protocol For Push To Talk Application In Mobile Ad Hoc Networks

Mobile ad-hoc networks comprise a type of wireless network that can be easily created without the need for network infrastructure or administration. These networks are organized and administered into temporary and dynamic network topologies. Unfortunately, mobile ad-hoc networks suffer from some limitations related to insufficient bandwidth. The proliferation of new IP Multimedia subsystem services (IMs), such as Push-to-talk (PTT) applications consume large amounts of bandwidth, resulting in degraded QoS performance of mobile ad-hoc networks. In this thesis, a Priority XCAST based routing protocol (P-XCAST) is proposed for mobile ad-hoc networks to minimize bandwidth consumption. P-XCAST is based on demand route requests and route reply mechanisms for every destination in the PXCAST layer. To build the network topology and fill up the route table for nodes, the information in the route table is used to classify the XCAST list of destinations according to similarities on their next hop. Furthermore, P-XCAST is merged with a proposed Group Management algorithm to handle node mobility by classifying nodes into two types: group head and member. The proposed protocol was tested using the GloMoSim network simulator under different network scenarios to investigate Quality of Service (QoS) performance network metrics. P-XCAST performance was better by about 20% than those of other tested routing protocols by supporting of group size up to twenty receivers with an acceptable QoS. Therefore, it can be applied under different network scenarios (static or dynamic). In addition Link throughput and average delay was calculated using queuing network model; as this model is suitable for evaluating the IEEE 802.11 MAC that is used for push to talk applications. The analytical results for link throughput and average delay were used to validate the simulated results

Research on Quality of Service Based Routing Protocols for Mobile Ad Hoc Networks

Quality of service (QoS) based routing protocols play a significant role in MANETs to maintain proper flow of data with efficient power consumption and without data loss. However, several network resource based technical challenges or issues are encountered in the design and implementation of QoS routing protocols that perform their routing function by considering the shortest route or the lowest cost. Furthermore, a secondary route is not reserved and alternative routes are not searched unless the established route is broken. The current structures of the state-of-the-art protocols for MANETs are not appropriate for today's high bandwidth and mobility requirements. Therefore, research on new routing protocols is needed, considering energy level, coverage, location, speed, movement, and link stability instead of only shortest path and lowest cost. This paper summarizes the main characteristics of QoS-based routing protocols to facilitate researchers to design and select QoS-based routing protocols. In this study, a wide range of protocols with their characteristics were classified according to QoS routing strategy, routing information update mechanism, interaction between network and MAC layer, QoS constraints, QoS guarantee type and number of discovered routes. In addition, the protocols were compared in terms of properties, design features, challenges and QoS metrics

Performance Enhancement of Routing in MANETs by using EOMD

Usually large scale of network applications requires communication of the single copy of same information packets simultaneously to many destinations. Applying the infrastructure- based multicast routing protocols in Mobile Ad hoc wireless Networks (MANETs) is a big challenge task. The circumstances that make Multicasting in ad hoc networks is extra intricate than in wired networks are node mobility, Interference of Wi-Fi alerts and broadcast nature of the communication. Tree based Protocols aren't suitable for common topology modifications as an excessive amount of overhead for updating the filter information and additionally no longer suitable for partition or isolation. The major impact of routing for multi-hop MANETs comes due to mobility of the node, as performance is prone to modifications in network topology. When any link breaks, the direction should be repaired or changed, similar to direction preservation or route discovery, respectively. The rerouting process charges in radio bandwidth and battery energy, and the extra routing latency can also affect QoS for community packages, degrading communication performance. The ODMRP is more robust to mobility and unreliable wireless links as its core layout relies on periodic floods of path discovery and renovation. ODMRP periodically reconstructs the ?forwarding mesh? on a fixed quick interval. The path refresh is the most essential parameter because it has the important effect at the protocol overhead. We proposed an Extended - On Demand Multicast Routing Protocol with motion detection (EOMD), which reduces communication overhead and performance improvisation in mobile Ad-Hoc Network in Mobility

Vulnerability Analysis of the Simple Multicast Forwarding (SMF) Protocol for Mobile Ad Hoc Networks

If deployments of Mobile Ad Hoc Networks (MANETs) are to become common outside of purely experimental settings, protocols operating such MANETs must be able to preserve network integrity, even when faced with careless or malicious participants. A first step towards protecting a MANET is to analyze the vulnerabilities of the routing protocol(s), managing the connectivity. Understanding how these routing protocols can be exploited by those with ill intent, countermeasures can be developed, readying MANETs for wider deployment and use. One routing protocol for MANETs, developed by the Internet Engineering Task Force (IETF) as a multicast routing protocol for efficient data dissemination, is denoted "Simplified Multicast Forwarding" (SMF). This protocol is analyzed, and its vulnerabilities described, in this memorandum. SMF consists of two independent components: (i) duplicate packet detection and (ii) relay set selection, each of which presents its own set of vulnerabilities that an attacker may exploit to compromise network integrity. This memorandum explores vulnerabilities in each of these, with the aim of identifying attack vectors and thus enabling development of countermeasures.Afin d'augmenter le nombre de déploiements de réseaux ad hoc dehors des "testbeds" purement expérimentals, des protocoles de routage des réseaux ad hoc doivent être en mesure de préserver l'intégrité du réseau, même lorsqu'ils sont confrontés avec des participants imprudents ou malicieux. Un premier pas vers la protection d'un réseau ad hoc est d'analyser les vulnérabilités du protocole de routage qui gère la connectivité du réseau. En comprenant comment ces protocoles de routage peuvent être exploités par des personnes ayant de mauvaises intentions, des contre-mesures peuvent être développées. Un protocole de routage pour des réseaux ad hoc, développé par l'Internet Engineering Task Force (IETF) comme protocole de routage de multicast pour la diffusion efficace des données, est appelé "Simplified Multicast Forwarding" (SMF). Ce protocole est analysé, et ses vulnérabilités décrites dans ce rapport. SMF est constitué de deux composantes indépendantes: (i) la détection des paquets dupliqués et (ii) la sélection des relais, dont chacun présente son propre ensemble de vulnérabilités qu'un attaquant peut exploiter pour compromettre l'intégrité du réseau. Ce rapport explore des vulnérabilités dans chacune des deux composantes, afin d'identifier les vecteurs d'attaque, ainsi de permettre de développer des contre-mesures

Hybrid Wireless Network Approach for QoS

Fast improvement of wireless networks has stimulated variety of wireless applications that have been used in number of areas such as commerce, emergency services, military, education, and entertainment. As wireless communication capture popularity, specific research has been devoted to supporting real-time transmission with Quality of Service (QoS) requirements for wireless network applications. At the same time, a wireless hybrid network that combines a mobile wireless ad hoc network (MANET) and a wireless infrastructure network has been considered to be a better option for the next generation wireless networks. By directly implementing resource reservation-based QoS routing for MANETs, hybrids networks inherit invalid reservation and race condition problems in MANETs
