In this paper, we propose a novel packet forwarding scheme based on network coding that is resilient to jamming attack in a tactical area. Wireless communication is necessary in a battlefield, but it is fragile to jamming attacks from an adversary because of the wireless shared medium. Jamming attack is easily achieved by emitting continuous radio signals and it can interfere with other radio communications...
Wireless Sensor Networks (WSN) are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. The sensors themselves can range from small passive micro sensors to larger scale, controllable weather-sensing platforms. In this work, we investigate how the sensor network performs in the...
In this paper, we combine network coding and tomographic techniques for topology inference. Our goal is to infer the topology of a network by sending probes between a given set of multiple sources and multiple receivers and by having intermediate nodes perform network coding operations. We combine and extend two ideas that have been developed independently. On one hand, network coding introduces topology-dependent...
One way to reduce the intercell interference in cellular networks is not to transmit strong signals from the cell borders towards the access points directly but rather to relay such transmissions to other users or relays within the cell by using much lower signal levels. This will produce much less interference in adjacent cells. For this reason, we present an intercell interference aware (IIA) network...
In this paper, we introduce and evaluate ScaleMesh, a scalable miniaturized dual-radio wireless mesh testbed based on IEEE 802.11b/g technology- ScaleMesh can emulate large-scale mesh networks within a miniaturized experimentation area by adaptively shrinking the transmission range of mesh nodes by means of variable signal attenuators. To this end, we derive a theoretical formula for approximating...
