The autonomous nature of Mobile Ad hoc Networks (MANETs) makes them suitable for the support of extreme emergency rescuer IP communications for next generation networks. A major hurdle towards the deployment of emergency MANETs (eMANETs) is the design of a distributed routing protocol that can adapt to its highly dynamic topology where the number of nodes in the network frequently varies. This paper...
A mobile agent is a particular type of agent with the ability to migrate from one host to another where it can resume its execution. Mobile agents can be used in applications for wireless network to save bandwidth and time. In this paper we consider dependability aspect, especially reliability issues that need to be addressed before the mobile agents can be used for a broad range of commercial applications...
Many protocols for distributed systems employ leasing mechanisms to recover from failures, where a leaseholder is granted access to data or services for a limited time (lease period. In such cases, choosing an appropriate lease period that is to be granted plays a crucial part in the fair and efficient access of data or services by the leaseholders. Existing algorithms vary lease periods with system...
With the growth of the Internet services, voice over IP (VoIP) has been playing a key role in cutting the costs of telephone calls. It can be seen that since the demand of VoIP over wireless network is growing, the use of VoIP over mobile ad-hoc network (MANET) is expected to grow as well. We have identified some of the challenging issues to ensure robust and secure voice communication over MANET...
Vehicle-to-vehicle/vehicle-to-infrastructure (V2X) communication systems are envisioned to greatly improve road safety, traffic efficiency, and driver convenience. However, many V2X applications rely on continuous and detailed location information, which raises location privacy concerns. A multitude of privacy-protection mechanisms have been proposed in recent years. However, few efforts have been...
Mobile ad-hoc network (MANET) is an appealing technology that has attracted lots of research efforts. Due to frequent communication failures, multipath routing is preferred than single-path routing in many applications such as multimedia streaming over MANET as the former can provide robustness, load balancing and reduce end-to-end delay. However, a security remains important factor that hinders the...
A very large number of simulation models have been developed to study ad hoc network architectures and protocols. Evaluating and deploying all sorts of protocols and applications designed for wireless ad hoc networks in a real environment is an important and urgent task. In recognition of this need, and to further our research objectives in the area of wireless ad hoc networks, we have built the E...
Mobile Ad hoc Networks (MANETs) are self configuring and self healing networks that do not require any existing infrastructure. As the nodes constituting the network are mobile, the network topology can be very dynamic. Hence, special routing protocols are designed to cater to the dynamic nature of MANETs. Optimized Link State Routing (OLSR) is once such protocol that has proven to be a potent routing...
To increase the availability of mission critical services and information in sparse MANETs with frequent and/or long term network partitions, we aim to develop efficient replication and placement algorithms. The prediction of the neighborhood of a node is one core element in these algorithms. In this paper we present a neighborhood prediction algorithm based on the Sequential Monte Carlo framework,...
Trying to provide safer and more efficient transportation solutions, the need for reliable and efficient communications is increasing in ITS (Intelligent Transportation Systems) use cases such as collaborative road data collection, driver information systems, infotainment or fully driverless vehicles. Applications that rely on vehicle-infrastructure (V2I) and vehicle-vehicle (V2V) communications have...
