The growth of laptops, personal digital assistant (PDA) and 802.11/Wi-Fi wireless networking made mobile ad-hoc network (MANET) a popular research topic recently. However, the flexible deployment nature and the lack of fixed infrastructure make MANETs suffer from a variety of security attacks. We, in this paper, discuss the Misleading Routing Attack (MIRA) in Mobile Ad-hoc Networks and propose a mitigation...
Mobile Ad hoc Network (MANET) is a network comprises of mobile nodes connected without any centralized administration. Each node in the network has the ability to share a large number of objects with other nodes. The nodes are connected with other nodes to forward a message to other nodes until the search for node that desire meets. This paper represents a new replication method to recover the performance...
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...
Recently, mobile devices have become increasingly affordable, reliable and pervasive in contemporary society. Meanwhile, cloud computing is playing an increasingly role in people's daily life. Together with these two promising technologies, Mobile Cloud Computing (MCC) has been introduced as a potential technology in future. However, since the mobility of cloud users in MCC, service availability becomes...
A Mobile Ad-hoc Network (MANET) is composed of Mobile Nodes (MNs) without any fix infrastructure. Currently, It is one of the most attractive research topics in the wireless communication. These MNs dynamically create temporary network and transferring messages from one MN to others in peer to peer fashion. A routing protocol runs on every mobile host and therefore subjected to the limitation of resources...
TCP attacks are the major problem faced by Mobile Ad hoc Networks (MANETs) due to its limited network and host resources. Although the session hijacking is not in the forefront of everyone mind, it still remains a commonly used attack in MANET. Session hijack attacks are defined as taking over an active TCP/IP communication session without their permission or knowledge. When implemented successfully,...
With the development of Mobile Internet, Accessing to the Internet or sharing data with others has become an important integral part of daily life. There exists one kind of networks whichbe calledinfrastructure less mobile network commonly known as mobile Ad Hoc network (MANET) plays a critical role to satisfy the demands above. Classical routing protocols of MANET like AODV, TORA or LAR are widely...
In the disaster-hit area, communication supporting systems using the existing mobile ad hoc network technique could not function as expected and communication would be interrupted from time to time, since they have not taken into consideration the issue of sleep, which is a very frequently used means for users to save their battery consumption. Especially, a phenomenon called sleep thrashing may occur,...
Offloading Technology Metropolitan Advanced Deliver Network (MADNET) which has been developed from several previous studies make the best solution to address the traffic density in a cellular operator. One of them is the implementation of third generation (3G), lately WiFi Offload is being developed, this is in line with the WiFi network in Urban and Metropolitan Networks. MANET is a technology which...
Extensive researches are going on in the area of wireless ad hoc networks focuses on a wide range. Among them, mounting efficient data broadcasting algorithms is considered to be an important research focus because the broadcast method is broadly used in a number of routing protocols and, since the devices in these networks usually have a limited power supply, simply adopting the broadcast methods...
Resource Allocation has been widely used for improving various performance metrics in wireless networks. Applying resource allocation to a Mobile Ad Hoc Network (MANET), however, is a challenging problem because of dynamic network topology. In this paper, we develop a novel resource allocation scheme designed for MANETs that minimizes the communication cost for accessing distributed resources while...
Asymmetric/unequal radio links (ARL) in wireless communication can occur in MANETs/VANETs for many reasons such as hardware limitations, power saving protocols, shadowing effects, dynamic spectrum managements. Although largely overlooked, these ARLs are responsible for problems like hidden stations and exposed stations. This paper presents how Extended Sliding Frame Reservation Aloha (ESFRA) solves...
Mobile Ad hoc Networks are wireless networks without an infrastructure which are set up for a temporary basis to serve a particular purpose with a specific period of time. In this Modern technology the aim of Mobile Ad hoc Networks is to provide seamlessly communication in wireless technology by adopting routing protocol functionality in the mobile nodes. Multimedia real time system like voice, data,...
Mobile Ad Hoc Networks (MANETs) are self organized networks whose nodes are free to move randomly while being able to communicate with each other without the help of an existing network infrastructure. Ad hoc on-demand distance vector routing (AODV) is demand driven one of the best and popular routing algorithm. AODV is severely affected by well-known black hole attack in which a malicious node injects...
Modern communication is containing different types of wireless networks as backbone for various applications used for different users. Mobile Ad-hoc Networks is the type of network which contains many mobile devices and provide good solution for many type communications for different applications military, industry and remote areas (flood hit areas, nuclear hit areas etc). Mobile Ad-hoc Networks prove...
To simulate crowds at mass events, realistic movement data of people is required. Despite their limited capacity for approximating real human mobility, synthetic movement models are traditionally used for this purpose. More realistic simulations can be achieved by using real-life movement data, gathered by observing people in the desired context. This paper presents a method for tracking people at...
This paper reviews task execution reliability in mobile ad hoc grid. We consider resource allocation for mobile ad hoc grids with centralized architecture in the presence of dependent tasks. Allocating appropriate resources for the tasks can avoid uncompleted tasks and ensure the service reliability. With the aim to increase service reliability, resource management can assign the same tasks to different...
Broadcast in mobile ad-hoc networks is a challenging and resource demanding task, due to the effects of dynamic network topology and channel randomness. In this paper, we consider 2D wireless ad-hoc networks where nodes are randomly distributed and move following a random direction mobility model. A piece of information is broadcast from an arbitrary node. Based on an in-depth analysis into the popular...
A mobile ad-hoc network (MANET) is a self-configuring, self-organized, and infrastructureless network of mobile stations, connected by radio links. The challenge to ensure network's operation means to continuously maintain updated information about the network's topology, the characteristics of the radio links and security at all levels. Due to the decentralized nature of the network, this is quite...
The collection of mobile nodes without infrastructure known as the mobile adhoc network has its nodes that moves independently towards all directions in the network thereby changing the network topology frequently. In MANET, whenever the node that is identified as source need to transfer data to the receiving node which resides out of coverage area, source node uses intermediate nodes. We use DOA...
