This paper describes the Flexible Internetwork Stack (FINS) Framework, an open-source tool to enable implementationbased experimental research in computer networking. The FINS Framework uses a module-based architecture that allows cross-layer behavior and runtime reconfiguration of the protocol stack. The FINS Framework is general enough to enable experimental setups under various network architectures (e.g., MANET, infrastructure, mesh) […]
Development of intelligent transportation system is the need of all the developing countries where urbanization and industrialization is rapidly growing. VANETs are being used as a tool for improving road safety by alarming the drivers about accidents occurred ahead of them or for providing internet access to the passengers via gateways along the road. Due […]
A mobile ad hoc network (MANET) is one consisting of a set of mobile hosts which can operate independently without infrastructure base stations. Power saving is a critical issue for MANET since most mobile hosts will be operated by battery powers. We can apply power conservation methods in all layers; but most of the power control mechanisms […]
In opportunistic networks, it is difficult to predict when a node encounters others and how long it keeps in contact with another. Nodes continually attempt to explore neighbor nodes in the vicinity to transmit data. In battery-operated devices, this persistent exploration consumes a great deal of energy. In this paper, we propose an optimal energy-efficient […]
Opportunistic networks are type of challenged mobile Ad-Hoc Networks (MANETs). In Opportunistic Networks (OppNets), mobile devices send out the messages by exploiting the unswerving contacts, without the requisite of an end-to-end communications. In such a system, nodes are sporadic and there does not subsist an ample path from source to destination customarily. The message forwarding […]
The increased popularity of wireless networks has enabled the development of Location Based Service (LBS) techniques that rely on wireless signal strength. These techniques are being used extensively in military, healthcare, industrial and other environments in Wireless Sensor Networks (WSNs) and Mobile Ad hoc Networks (MANETs). In some networks, it is important to keep track […]
In mobile ad-hoc networks (MANETs), there are selfish nodes, which drop the received data packets, because nodes have limits of their resources. Secure routing protocols are developed as one of security mechanisms. In secure routing, each node can detect selfish nodes and decide secure paths by consulting trust values. Here, trust values express reliability for […]
The use of directional antennae in ad hoc networks can provide high spatial reuse of spectrum and antenna gains. However, employment of directional antennae poses great challenges such as hidden terminal and deafness problems. The existing directional medium access control (DMAC) protocols usually work in a switching mode of omnidirectional listening and directional sending, which, […]
Security is the main concern in today’s wireless network environment. However, cipher algorithms consume a lot of resources to provide the required confidentiality. Ad-Hoc wireless networks are one area where the devices are extremely resource constrained. Therefore computationally simple yet cryptographically strong cipher algorithms are required for such kind of networks. In this paper a […]
With the advent of wireless communication networks and the new generation of smartphones, the access to data transmission networks has become possible anywhere at any time. Today, a group of users can gather in a dynamic manner and set up their own ad hoc communication networks and share geolocalization information thought Global Position System (GPS). […]
