MANET (mobile ad hoc network) technology has become increasingly attractive for real-world applications in the past decade. Dynamic and intermittent connectivity caused by node mobility poses a huge challenge to the operation of MANETs that require end-to-end paths for communication. The attacks against critical nodes could result in a more degraded network service. In this paper, we evaluate the...
With the rapid advancement of wireless technology and the exponential increase of wireless devices in the past decades, there are more consumer applications for MANETs (mobile ad hoc networks) in addition to the traditional military uses. A resilient and robust MANET is essential to high service quality for applications. The dynamically changing topologies of MANETs pose a huge challenge to normal...
In order to understand the role of critical nodes in mobile ad hoc networks (MANETs), dynamic topologies are modelled as time-varying graphs and network topologies within a certain time window are aggregated as a weighted static graph. Critical node behaviour has been previously studied by evaluating how end-to-end throughput is impacted by the removal of high centrality nodes. However, different...
The application of complex network models to communication systems has led to several important results: nonetheless, previous research has often neglected to take into account their temporal properties, which in many real scenarios play a pivotal role. At the same time, network robustness has come extensively under scrutiny. Understanding whether networked systems can undergo structural damage and...
This paper presents a summary of work aimed at making current multihop routing in mobile ad hoc networks more sensitive to node mobility and ultimately improve routing performance in the face of node mobility. We discuss the various existing mobility tracking parameters, how they capture node mobility and also their shortfalls. We propose some mobility tracking schemes(heuristics) based on one of...
This work is focused on explore different heuristics that may be applied to provide a link-based cost for energy-aware multihop routing for wireless environments which integrate heterogeneous devices that are carried or owned by Internet end-users. We propose to analyze based on simulations of the different heuristics when applied to both distance-vector and link-state approaches, namely the AODV...
We investigate the performance of a new distributed protocol for setting up and maintaining a backbone for multi-hop mobile networks with multiple radio interfaces. Our solution, termed MM-Backs, is effective in producing backbones with limited size, while being robust and reliable in the face of node mobility. We compare our protocol with a solution for mobile backbones running in single-radio networks...
Intelligent Transportation Systems (ITS) aggregate, analyze and display geographic- and temporal-specific sensor information to reduce congestion while promoting safety. Until now, the coverage and potential of ITS have been restricted by the excessive cost of deploying the required road sensor and communications infrastructure. Our solution to this problem is focused on a novel integrated ITS Network...
The application of complex network theory to communication systems has led to several important results. Nonetheless, previous research has often neglected to take into account their temporal properties, which in many real scenarios play a pivotal role. Mainly because of mobility, transmission delays or protocol design, a communication network should not be considered only as a static entity. At the...
Mobile tactical networks are characterized by their extremely low bandwidth and require performance optimisations in order to support both voice and data traffic. In this paper, we propose a cross-layer architecture to achieve this. The proposed architecture maintains a clean horizontal interface between layers to maintain interoperability while also allowing layers to share their operational state...
