Current Perspectives for Autonomous Sensor Nodes

FLEHAP: A Wind Powered Supply for Autonomous Sensor Nodes

The development of the Internet of Things infrastructure requires the deployment of millions of heterogeneous sensors embedded in the environment. The powering of these sensors cannot be done with wired connections, and the use of batteries is often impracticable. Energy harvesting is the common proposed solution, and many devices have been developed for this purpose, using light, mechanical vi...

Efficient Search Algorithms using Autonomous Mobile Sensor Nodes

In this paper, we propose search algorithms using multiple autonomous and cooperative mobile sensor nodes (MSN). Our goal is to minimize the total search time and the travel distance of MSNs in a given search area while enabling cooperation among the MSNs and tolerating possible failures of one or more MSNs. We first describe a Lane Based Search (LBS) strategy in which each mobile sensor node i...

Software Verification for Sensor Nodes

We look at software written for wireless sensor nodes, and specialize and develop on the state of the art in software verification techniques for standard C programs (CBMC and SatAbs from the CProver suite) in order to locate programming errors in sensor applications before the software’s deployment on motes. Ensuring the reliability of sensor applications is an exemplary difficult problem for ...

A novel key management scheme for heterogeneous sensor networks based on the position of nodes

Wireless sensor networks (WSNs) have many applications in the areas of commercial, military and environmental requirements. Regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. A basic approach for preparing a secure wireless communication in WSNs, is to propose an efficient cryptographic key management protocol be...
