The high vulnerability of the wireless sensor nodes to jamming arises from the low resilience and easy differentiability of protocol control messages, and the high predictability of node wakeup schedules. In this paper, we propose Jam-Buster — a jam-resistant solution for WSN, orthogonal to the existing antijamming solutions, that increases resilience ...

Bounds on the Lifetime of WSNs
2013 IEEE International Conference on Distributed Computing in Sensor Systems, 2013Energy is one of the most important resources in wireless sensor networks (WSN). Energy directly translates to lifetime which is an important ingredient of performance control in WSNs. We use an idealized mathematical model to study the impact of routing on energy consumption.

ZigBee Network Layer, the main purpose of the agreement is to provide reliable and secure transmission. There are three kinds of networks topology in ZigBee Network Layer: Star topology, Tree topology, Mesh topology. This study was used in the experiment of the packet size and speed are not great, postponed plans did not change significantly.

Erlang meets WSNs: A functional approach to WSN programming
2012 IEEE International Conference on Pervasive Computing and Communications Workshops, 2012The scarce diffusion of Wireless Sensor Network systems is due to several factors, among them the complexity in designing, programming and testing applications for this technology. Too often too specialized solutions have been proposed for specific scenarios, impeding code reuse and supporting poorly engineered development methodologies (i.e. “code and

Viticulture Zoning by an Experimental WSN
International Journal of Information Technology and Web Engineering, 2009Biological research in agriculture needs a lot of specialized electronic sensors in order to fulfill different goals, like as: climate monitoring, soil and fruit assessment, control of insects and diseases, chemical pollutants, identification and control of weeds, crop tracking, and so on. That research must be supported by consistent biological models

ES-WSN: Energy Efficient by Switching between Roles of Nodes in WSNs
2015 IEEE Global Communications Conference (GLOBECOM), 2014The objective of our work is to propose a new approach called ES-WSN (Energy Efficiency by Switching between roles in WSNs) for the efficient use of energy in wireless sensor networks (WSN). Our solution ES-WSN extends the lifetime of the nodes in the network and guarantees a fair evolution of their level of energy.

Undervolting in WSNs: Theory and Practice
IEEE Internet of Things Journal, 2015Adapting the voltage level of a processing unit to the actual system load leads to an increased energy efficiency. The aim is to extend the battery lifetime, but existing voltage scaling approaches still act with reserve. To reduce the energy consumption even further, it is possible to power the electric circuits below the specified voltage levels ...

Collaborative authentication in unattended WSNs
Proceedings of the second ACM conference on Wireless network security, 2009An unattended wireless sensor network (UWSN) might collect valuable data representing an attractive target for the adversary. Since a sink visits the network infrequently, unattended sensors cannot immediately off-load data to some safe external entity.
