SASHA: A Distributed Protocol for Secure Application Deployment in Shared Ad-HocWireless Sensor Networks

Download Now Free registration required

Executive Summary

Wireless ad-hoc sensor networks in industrial settings often consist of multiple independent parties, each owning a subset of the nodes. In order to reduce costs, minimize time to market and increase coverage and functionality, these parties must share the capabilities of their individual sensor nodes; this creates a multi-owner and multi-application environment that requires advanced and secure mechanisms to control the deployment and operation of sensor applications. Although there is clear demand like in transport & logistics, state-of-the-art on secure application deployment in WSNs is lacking support for this sharing of sensor nodes.
