This paper studies the problem of routing in a multilayer (communication and social) network. Network protocols, such as link state routing and its variants, heavily used in mobile ad hoc networks (MANETs) cannot sustain robustness and efficiency as the topological information becomes easily stale with fast network dynamics. Attempts to collect and exchange excessive network information would result...
A Mobile Adhoc Network (MANET) is featured by multi hop wireless connectivity with topology change due to highly mobile stations with autonomous configuration ability. Therefore, it is very challenging to develop vibrant and resourceful routing Protocol for MANET which also performs excellent routig with security feasibility. This paper presents a detailed study and analysis of various routing issues...
This paper presents a novel method of selecting an optimal path between the nodes for data transmission in mobile ad hoc network. Mobile ad hoc network is a temporary, infrastructure-less network that communicates in multi-hop manner. Routing is an important issue in mobile ad hoc networks. Normally, routing protocol may selects the path between two nodes based on multiple metrics like distance between...
Due to their intrinsic characteristics, Ad Hoc mobile networks could be subjects to disturbances or node break-downs. The latter are worsened by the nodes relay and mobility features. A more sophisticated Multihoming integration to MANET networks necessarily increases its robustness: in other words, it improves its performances. That is why we suggest in this article a new extension of the Stream...
Different from previous works that mainly focus on deriving the scaling results for secrecy throughput of mobile ad hoc networks (MANETs), this paper studies the exact secrecy throughput of a cell-partitioned MANET with groupbased scheduling to eliminate interference from simultaneous transmissions. The concept of secrecy guard zone is introduced to allow each transmitter detect the existence of eavesdroppers...
A mobile adhoc network is an independent system of mobile stations associated by wireless link to form a system. This system can be modeled in the form of an uninformed graph. Adhoc networks are peer to peer, multihope networks were data packets are transmitted to a source to destination through intermediate nodes (which serve as router). The infrastructure is not the main issue to setup MANET and...
For the most existing MAODV protocol is only improved by a single performance, there is a problem that the comprehensive performance of the protocol cannot be improved as well. By uses of the routing selection mechanism with the constraints of bandwidth, delay and packet loss rate of the original protocol, a new multi-objective routing protocol RCQ-MAODV of mobile ad hoc network is put forward. Simulations...
The limited capacity of batteries of nodes imposes a constraint on ad hoc networks. Thus, energy efficiency is critical to prolong the network lifetime. Network traffic should be routed such that the energy consumption is minimized. In this paper, we discuss the energy-efficient multicast problem in ad hoc networks with the respect of delay. Multicast routing deals with finding a multicast tree, which...
Delay and capacity (throughput) are two important parameters to route data packets in Mobile Ad Hoc Networks (MANETs). In this paper, a new connectionless routing algorithm has been proposed to overcome the performance limit. The proposed algorithm is an extension of dynamic virtual route (DVR) algorithm. Mobility degree of nodes' neighborhood is used to calculate two mobility metrics. Mobility metrics...
Service discovery is an integral part in establishing an independent and self-organizing mobile ad-hoc network(MANET). In this paper a new distributed semantic service discovery scheme is proposed for MANET consisting of various mobile terminals. The proposed scheme based on the proactive routing protocol, Destination-Sequenced Distance Vector (DSDV), maintains the information on the network in the...
Nodes in Mobile Adhoc Network (MANET) are highly mobile. As a result, network topology and neighbouring nodes of each node vary abruptly which affects the communication. Communication also fails when a node intrude from one network to another. Communication goes well until every node is within its range, else transmission fails. Therefore it is necessary to build an efficient routing to solve this...
A mobile ad hoc network is much more assailable to attacks than a wired network due to its limited physical security, high mobility and lack of centralized administration. Jellyfish is a new denial of service attack. There are three kinds of JellyFish attacks i.e. JF Reorder Attack, JF Periodic Dropping Attack, JF Delay Variance Attack. In JF delay variance attack, intruder node needs to intrude into...
In highly dynamic airborne networks, multi-hop routing becomes increasingly difficult due to high mobility, intermittent links and link quality, and the need to scale. Traditionally, airborne tactical networks have leveraged existing MANET proactive, reactive, and hybrid routing protocols with modifications for cross-layer information, to provide multihop routing. Although there has been some success...
Ad Hoc networks usually consist of mobile nodes, which are characterized by lower computing and energy resources. For real-time streaming applications, choosing the shortest path for these kinds of sessions is insufficient. Such networks must operate energy-efficiently to maximize the lifetime of mobile devices and applications. In this paper we develop a energy-ware and delay-aware routing approach...
In order to ensure a reliable and efficient end-to-end communication among the network nodes in a Mobile Ad Hoc Network (MANET), an appropriate routing protocol is needed. In this paper, we present an extensive simulation-based comparison of three well-known MANET routing protocols (AODV, DSDV and OLSR) evaluating their performance in three real-life scenarios. Considering various performance metrics...
Video streaming is not possible between nodes in different partitions of a Mobile Ad-Hoc Network (MANET). However, ferry nodes can be used to deliver video in this environment. This service is helpful in some application scenarios, like emergencies. An important problem arises when the capacity offered by such a delay-tolerant network is not enough to deliver all the video produced. Then, video adaptation...
Wireless links are often asymmetric due to the heterogeneity in transmission power of devices, the limitation of node energy, different antenna gain among nodes and non-uniform environmental noise. Nevertheless, most of the routing algorithms for ad hoc networks assume that all wireless links are bidirectional, such algorithms are not able to react to or exploit the full connectivity of the network...
A MANET (Mobile Ad Hoc Network) can support large as well as small scale network topology. Based upon our specific small scale MANET requirement, we have taken the combination of horizontal and vertical topology with less number of nodes to check how the various MANET protocols like pro-active (DSDV) and re-active (AODV and DSR) performs in this manner. In this research study, we have observed these...
Research on routing in a network of intelligent, lightweight, micro and nano-technology sensors deployed in or around the body, namely Body Area Network (BAN), has gained great interest in the recent years. In this paper, we present an energy efficient, thermal and power aware routing algorithm for BANs named Energy Efficient Thermal and Power Aware routing (ETPA). ETPA considers a node's temperature,...
Wireless ad hoc routing protocols must employ accurate and rapid link failure detection mechanisms in order to maintain valid multihop routes and provide high data delivery rates. Hello-based failure detection is the predominant failure detection mechanism due to its ease of implementation. Despite its prevalence, no analytical work has been carried out to better understand its fundamental behavior...
