Qos and Security in Energy-Harvesting Wireless Sensor Networks

Free registration required

Executive Summary

Wireless sensor networks are composed of small nodes that might be used for a variety of purposes. Nodes communicate together through a wireless connection that might be subject to different attacks when the network is placed in hostile environments. Furthermore, the nodes are usually equipped with very small batteries providing limited battery life, therefore limited power consumption is of utmost importance for nodes. This is in clear opposition with the requirement of providing security to communications as security might be very expensive from the power consumption stand point.
