We solve the problem of localizing and tracking household objects using a depth-camera sensor network. We design and implement Kinsight that tracks household objects indirectly - by tracking human figures, and detecting and recognizing objects from human-object interactions. We devise two novel algorithms: (1) Depth Sweep - that uses depth information to efficiently extract objects from an image, and (2) Context Oriented Object Recognition - that uses location history and activity context along with an RGB image to recognize objects at home. We thoroughly evaluate Kinsight's performance with a rich set of controlled experiments. We also deploy Kinsight in real-world scenarios and show that it achieves an average localization error of about 13 cm.

In this work, we present the process of identifying potential vulnerabilities in 6LoWPAN enabled networks through fuzzing. the 6LowPAN protocol has been designed by the IETF as an adaptation layer of IPv6 for Low power and lossy networks. the fuzzing process is build upon the Scapy packets manipulation library. It provides different mutation algorithms to be applied on 6LoWPAN protocol messages to assess its implementations security and robustness. the protocol behaviors are described using an XML format to define different testing scenarios.

In this paper, we propose an efficient planarization algorithm and a routing algorithm dedicated to Unit Disk Graphs whose nodes are localized using the Virtual Raw Anchor Coordinate system (VRAC). Our first algorithm computes a planar 2-spanner under light constraints on the edge lengths and induces a total exchange of at most 6n node identifiers. Its total computational complexity is O(n Delta), with Delta the maximum degree of the communication graph. the second algorithm that we present is a simple and efficient algorithm to route messages in this planar graph that requires routing tables with only three entries. We support these theoretical results by simulations showing the robustness of our algorithms when the coordinates are inaccurate.

In this paper, we develop a new power-efficient algorithm for Wireless sensor Networks (WSN) in order to obtain, in a distributed manner, the Projection of an observed sampled spatial field on a subspace of lower dimension. this is an important problem that is motivated in various applications where there are well defined subspaces of interest (e. g. spectral maps in cognitive radios). As opposed to traditional Gossip Algorithms used for subspace projection assuming separation of channel coding and computation, our algorithm combines Computational Coding and a modification of existing Gossip Algorithms, achieving important savings in convergence time and yielding an exponential decrease in energy consumption as the size of the network increases.

Embedded devices connected to the Internet will start an increasing growth of the Internet in near future. Wireless sensor Networks (WSN) will play a major role in that growth. In the past several solutions were proposed to make sensor networks IP capable. Today there are IPv6-Stacks available including web servers running on sensor nodes. However, a gateway is always needed to convert the routing protocols and MAC-Layer Protocols including compression of IP packets to run on these devices. the overhead using IPv6 on the nodes is very high in respect of code size and message overhead. therefore, in our approach we design and implement a system based on simple protocols target for sensor network nodes and a flexible gateway working in a hybrid fashion for our sensor network testbed. We successfully integrated this non-IP WSN in the Internet and our testbed is productive available from any computer connected to the Internet for reference. In this paper we present the architecture of our solution and present the implementation details of a standard WSN application that can be used for evaluation.
