Survey on Mobile Ad Hoc Network Routing Protocols

Abstract: mobile ad-hoc network is characterized as network without any physical connections. In this network there is no fixed topology due to the mobility of nodes, interference, multipath propagation and path loss. Many Routing protocols have been developed to overcome these characteristics. The purpose of this paper is to review existing mobile ad-hoc proactive and reactive routing protocols depending on their proactive and reactive nature respectively. This review paper provides an overview of these protocols by presenting their characteristics, functionality, benefits and limitations and then makes their comparative analysis so to analyze their performance. The objective of this review paper is to provide analysis about improvement of these existing protocols.

Adhoc On-demand Distance Vector - Energy Efficient Approach

Abstract: nodes of Mobile Adhoc Network (MANET) are mobile in nature, overall network lifetime is one of the key challenges in MANET. To improve overall network lifetime along with packet delivery fraction and normalized routing load, this paper proposed an optimised multihop routing protocol (OMR-AODV) as an extension of Adhoc On-demand Distance Vector (AODV) by introducing threshold limit on residual battery of mobile node during route establishment phase. AODV and OMR-AODV are simulated with various parameters using network simulator and results shows that OMR-AODV performs better than AODV for overall network lifetime along with packet delivery ratio and normalized routing load.

A Survey on DHT-Based Routing for Large-Scale Mobile Ad Hoc Networks

Abstract: Mobile ad hoc networks (MANETs) are infrastructureless and distributed communication systems that require sophisticated approaches to routing to cope with node mobility and heterogeneous application requirements. In the past few years, distributed hash table (DHT) has come forth as a useful additional technique to the design and specification of spontaneous and self-organized networks. Researchers have exploited its advantages by implementing it at the network layer and developing scalable routing protocols for MANETs. The implementation of DHT-based routing in a MANET requires different algorithms and specifications compared to routing in the Internet because a MANET has its unique characteristics, such as node mobility, spontaneous networking, decentralized architecture, limited transmission range, dynamic topology, and frequent network partitioning/merging.In this article, we present a comprehensive survey of research related to DHT-based routing that aims at enhancing the scalability of MANETs. We present a vivid taxonomy of DHT-based routing protocols and the guidelines to design such protocols for MANETs. We compare the features, strengths, and weaknesses of existing DHT-based routing protocols and highlight key research challenges that are vital to address. The outcome of the analysis serves as a guide for anyone willing to delve into research on DHT-based routing in MANETs.

MANET routing protocols taxonomy

Abstract: This paper provides researchers many structures for mobile Ad hoc protocol that also could be implemented in VANET protocols. In the literature, there are numerous mobile Ad hoc network (MANET) routing protocols aiming to find the most suitable path from source to destination. Therefore these protocols should be categorized and classified. This classification helps in understanding, analyzing, comparing, and evaluating the routing protocols. Also, the classification can assist researchers and designers to differentiate the characteristics of the routing protocols and to find the relationships between them. The routing protocols cannot be included under one category or one classification, therefore, the known characteristics should be listed and the MANET routing protocols classified according to these attributes. In this paper, varies routing protocol classifications are presented that depend on design philosophy, on network structure, or on the routing protocol characteristic (packet casting and network routing metrics).

Beyond Opportunistic Networking Protocols: a Disruption-Tolerant Application Suite for Disconnected MANETs

Abstract: Delay/disruption-tolerant networking and opportunistic networking have emerged as promising solutions to support communication between people in environments devoid of any infrastructure network. Although many protocols have been proposed in the literature to support message forwarding or message dissemination in such conditions, a very few of these protocols have been implemented in fully-functional communication systems, and can thus be used to conduct experiments with real applications and real users. In this paper we present an application suite we designed in order to provide people with opportunistic communication means such as email, text and voice messaging, file sharing, etc. We also present some results of a preliminary experimentation campaign we conducted in order to evaluate these applications in a real setting.
