Wireless sensor networks (WSNs) consist of many sensors working as hosts. These sensors can sense a phenomenon and represent it in a form of data. There are many applications for WSNs such as object tracking and monitoring where the objects need protection. Providing an efficient location privacy solution would be challenging to achieve due to the exposed nature of the WSN. The communication protocol...
The Smart Grid (SG) is one of the latest emerging and rising models for modernizing traditional electrical power grids, and wireless communication is considered as a major building block in realizing SG. SG applications enable electrical devices to be interconnected and communicate with each other, requiring pervasive control of these actors. Therefore, wireless sensor network-based applications are...
The Time Slotted Channel Hopping (TSCH) Medium Access Control (MAC) has been introduced in the recent IEEE 802.15.4e amendment to improve energy efficiency and reliability of short range wireless communications in industrial applications. However the joining phase can take very long time due to the operation of TSCH and beside being a problem in the deployment phase it may become a relevant source...
This paper proposes a new approach to cope with the challenges in sensor localization in an obstructed environment even in the presence of channel noise. In particular, a progressive localization scheme is proposed that does not necessitate the need for any cluster as most existing schemes do. Initialization is done by generating a quadrilateral of sensor nodes where the connectivity weight between...
Using UWB for wireless short range, low rate communication is attracting growing interest due to its low power consumption and very high bandwidth. Regarding these qualities, it is comprehensible that there is an interest in the automation industry to use ultra-wideband-based wireless sensor nodes to replace wired systems, to save energy and to save costs without reducing the reliability of the whole...
Providing data confidentiality for energyconstrained devices has proven to be a hard problem. Over the years many efficient implementations of well-known block ciphers, as well as a large number of new “lightweight” block ciphers, have been introduced. We propose to distribute block ciphers encryption and decryption operations between a subset of “trusted” nodes. Any block cipher, lightweight or not,...
