This paper discusses the challenges in developing an IoT platform for registering, discovering and composing heterogeneous services from multiple provider types, viz., Wireless Sensor Networks (WSNs), Web Service Providers (WSPs), and Autonomous Service Providers (ASPs), without human intervention. The platform executes a service composition in a decentralised fashion, with a mechanism to detect service...
Public social environments are hot beds of security leaks, either they are virtual or physical. The nature of social settings allows numerous people to co-exist in the same space. This close un-bounded proximity opens up the possibility of privacy compromise in such environments. In this paper, we explore a novel and practical multi-modal side-channel keystroke recognition system, named ClickLeak,...
We experimentally compare OFDM and Single-carrier modulation in a large-capacity optical-wireless signal delivery system at W-band. We conclude that OFDM is more suitable in a scenario of relatively short wireless distance and limited receiver bandwidth.
This paper presents the magnetic field modeling-based energy efficient routing for WSN which models the routing problem as a current-carrying solenoid and a free to turn magnet put into a uniform magnetic field respectively. The optimal routing is then performed through the path with the maximum generated magnetic field intensity for the solenoid technique and with minimum torque for the magnetic...
Recent advances in ambient energy-harvesting technologies have made it possible to power wireless sensor networks (WSNs) from the environment for long durations. However, the energy availability in an energy-harvesting WSN varies with time and thus may cause the network topology to evolve over time. In this paper, we study the topology design problem in a time-evolving and energy-harvesting WSN where...
Routing in wireless networks has been heavily studied in the last decade and numerous routing protocols were proposed in literature. The packets usually follow the shortest paths between sources and destinations in routing protocols to achieve smallest traveled distance. However, this leads to the uneven distribution of traffic load in a network. For example, wireless nodes in the center of the network...
Topology control in wireless ad hoc and sensor networks has been heavily studied recently. Different geometric topologies were proposed to be the underlying network topologies to achieve the sparseness of the communication networks or to guarantee the package delivery of specific routing methods. However, most of the proposed topology control algorithms were only applied to 2D networks where all nodes...
