MANET is a continuously self-configuring, infrastructure less networks consisting of mobile devices which are connected by no any wired connection. Mobile devices are always in moving state. While transmission of data from one node to another the nodes establish a path with the help of intermediate nodes. Due to the mobility of nodes in the network the malicious nodes can be easily introduced in the...
As mobile devices have become more powerful and ubiquitous in our daily life, sharing content objects among mobile platforms has become increasingly popular. Without the help of server infrastructures, clients usually form a mobile peer-to-peer (P2P) system as an ad-hoc network, and discover content objects by flooding query to neighboring peers. Such a flooding-based query method consumes communication...
Mobile ad hoc Networks refers to the infrastructure less, resource poor wireless networks whose interaction is unplanned in such a way that location of participating nodes and parties can not be identifiable. The mobile devices are used by people to access services in various environments. Before two or more mobile networks ready to interact, they must trust that each will satisfy the security and...
A mobile ad hoc network (MANET) is characterized by its dynamic and decentralized topology, which allows exchanging information between mobile nodes without any pre-existing telecommunications infrastructure. However, mobile devices have constrained resources like memory, energy, bandwidth, etc., that must be optimally used in situations where a MANET is needed. For that reason, we propose a greener...
Emerging multimedia applications over mobile devices are becoming very popular, especially over infrastructure wireless networks such as cellular and WLANs. However, providing this kind of services over infrastructure-less networks like ad hoc networks presents many additional problems. One of these problems is how to share resources fairly among the users involved. In this article we propose a QoS...
To deal with the challenges posed by device capacity and capability, and also the nature of ad hoc networks, service discovery model is needed that can resolve security and privacy issues with simple solutions. The use of complex algorithms and powerful fixed infrastructure is infeasible due to the volatile nature of mobile ad hoc environment and mobile devices. This paper presents a Secure and Lightweight...
The mobile ad hoc networks (MANET) is autonomous, infrastructureless network. Unlike the common Web service used in wired applications, the web service applications based on MANET have so many differences in data transmission, service registration and service discovery. All components of web service of MANET need to consider the features of mobile devices and mobile environment. Considering the characters...
This paper describes middleware that establishes a MANET environment with mobile devices and exchanges contents in the devices. The middleware also provides a sharing function as a common service among mobile devices.
Three data communication methods can be provided in a MANET: data broadcast, data query, and peer-to-peer messaging. The formation of heterogeneous distributed mobile databases within a MANET that allows people to submit queries or transactions is becoming a reality. Previously, the DD3M data communication protocol (distributed database with 3 communication modes) has been proposed for providing all...
New social networks are born each day, at a formal conference, at informal social gathering, at family reunions etc. Internet has already been playing an important role in modern way of socialising. But it is still not the optimal way of interaction as one has to be very active updating profiles. With the easy access to mobile devices, modern technologies have now started to adopt to new ways of socialising...
This paper proposes a novel IPv6 address autoconfiguration that works with multiple types of mobile networks, such as MANET, NEMO, MANEMO, as well as regular IPv6 networks. Our proposed algorithm assigns unique addresses to mobile devices without performing duplicate address detection. As a result, an address autoconfiguration can be done rapidly. This is suitable for system that requires dynamic...
Mobile ad hoc network is a self-organized network made up of mobile devices. It is also often termed an infrastructure-less, spontaneous and dynamic network. Due to the temporary cooperation among nodes, and no enough knowledge between each node in advance, it is difficult to establish trust in ad hoc network. In this paper, a novel cluster-based trust model for ad hoc networks was presented and an...
The Mobile Ad-Hoc Networks (MANET) are more and more important due to their increasing use. At the same time, the Trusted Computing Group (TCG) approach in using TPM based hardware root of trust is increasingly used in mobile devices providing a trustable source of knowledge about software composition of devices. In this paper, we develop a new approach to evaluate trust among peers in an Ad Hoc network,...
