Privacy, in particular anonymity, is required to increase the acceptance of users for the Internet of Things (IoT). The IoT is built upon sensors that encompass us in each step we take. Hence, they can collect sensitive, privacy-invading data that can be used to establish complete user profiles. For this reason, sensing in the IoT needs to provide means of privacy-protection. In this paper, we discuss...
In this paper, we consider the use of an electric-supplied coordinator exploiting much higher transmission power than battery-supplied nodes in low power and lossy networks (LLNs). Since the coordinator can transmit via one hop instead of multiple hops over downlink, it is possible to reduce the communication overhead significantly. To take this advantage, we propose a single hop downlink protocol...
The medium access control being the main source of energy wastage in wireless sensor networks, energy-efficiency is always kept in mind while designing the communication stack. Especially, versatile preamble-sampling MAC protocols emerged to offer a suitable solution over multiple deployment characteristics. For instance, some works have targeted burst transmissions while others have focused on long-term...
Disruption Tolerant Networks (DTNs) are characterized by frequent network partitioning. This causes network connectivity to be opportunistic. In recent years, many collaborative applications have been envisioned for DTNs. These applications rely on the availability of reliable group communication protocols. To address this challenge in DTNs, we propose a scalable multicasting scheme that deterministically...
Most of the proposed communication protocols for wireless sensor networks focus on the energy efficiency. However, it often brings poor latency performance. In this paper, we develop a novel cross-layer designed asynchronous protocol EEFF (Energy Efficient and Fast Forwarding) for wireless sensor networks regarding low latency and energy efficiency. EEFF improves low power listening approach and introduces...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
Cheap programmable sensor devices are becoming commercially available. They offer the possibility of transforming existing enterprise applications and enabling entirely new ones. The merging of sensor networks into the enterprise network poses some distinct problems. In particular, information from theses devices must be obtained in a way which minimizes their energy use and must be aggregated and...
