Autonomous Access Control among Nodes in Sensor Networks with Security Policies

摘要

This paper describes a new framework of policy control sensor networks. Sensor networks are shared by various applications, and have many nodes. Hence, sensor networks need to have ability to accept various applications, and to deploy application modules to nodes easily. Sensor nodes should have appropriate application modules. A framework that is based on VPC on KODAMA enables sensor nodes to have appropriate modules by assignment rules in a policy. When users only put application policies to sensor networks, sensor nodes propagate the policies and perform appropriate roles in the applications. This paper also shows that sensor networks with policies change behavior corresponding to detected active RFID tags as an example.
