Mobile Adhoc networks are gaining popularity in today’s dynamic environment. These are characterized by high mobility, infrastructureless, self organizing, quick deployability and resource constrained networks. The network depends on cooperation among nodes for any communication. High mobility and dynamic architecture of mobile adhoc network make it vulnerable to security issues. Trust plays an important role […]
A broadcast operation is the fundamental transmission technique in mobile ad-hoc networks (MANETs). Because a broadcast operation can cause a broadcast storm, only selected forwarding nodes have the right to rebroadcast a broadcast message among the one-hop and two-hop neighboring nodes of a sender. This paper proposes a novel algorithm to minimize broadcasting redundancy in […]
Existing narrowband mobile ad-hoc networks (MANETs) used in disaster search and rescue (SAR) missions and tactical communications are specifically designed to enable robust unicast or broadcast voice communications. The increasing demand for add-on data services such as messaging, file and map transfer etc requires those long-range communication systems to provide higher data rates while maintaining […]
Virtual warning system which is an integral component of Intelligent Transportation System (ITS) can be realized through geocasting in vehicular ad-hoc networks (VANETs). It enhances road safety and security by targeting a group of vehicles within a specified geospatial region, called Zone of Interest (ZOI) rather than an individual vehicle. Velocity of the node and […]
Delay Tolerant Networks (DTNs) are sparse mobile ad-hoc networks in which there is typically no complete path between the source and destination. Multicast is an important group communication paradigm that is required by many potential DTN applications, such as data dissemination during military and rescue operations. While multicasting has been studied extensively in the context […]
The outage probability and average bit error rate (BER) of wireless digital systems in a Nakagami-m fading environment have been well analyzed in the literature. Most of the analysis considers static wireless terminals in which the received signal power follows a gamma distribution. However, many mobile and ad-hoc networks (MANETs) comprise of mobile receiving nodes […]
This paper reports experimental results on self-organizing wireless networks carried by small flying robots. Flying ad hoc networks (FANETs) composed of small unmanned aerial vehicles (UAVs) are flexible, inexpensive and fast to deploy. This makes them a very attractive technology for many civilian and military applications. Due to the high mobility of the nodes, maintaining […]
Mobile Opportunistic Network (MON) is characterized by intermittent connectivity where communication largely depends on the mobility pattern of the participating nodes. In MON, a node can take the custody of a packet for a long time and carry it until a new forwarding path has been established, unlike mobile adhoc network (MANET), where a node […]
This paper studies the delay constrained multicast capacity of large scale mobile ad hoc networks (MANETs). We consider a MANET that consists of ns multicast sessions. Each multicast session has one source and p destinations. Each source sends identical information to the p destinations in its multicast session, and the information is required to be delivered to […]
The Virtual Node Layer (VNLayer) is a clusterbased approach to handle communications in mobile ad-hoc networks (MANETs), furnishing an abstraction of fixed geographical regions served by virtual nodes as a means to tackle the challenges raised by the mobility of the physical nodes. Several studies have proved that the VNLayer constructs can be applied to […]
