Dynamic Context Networks of Wireless Sensors and RFID tags

Current research on pervasive systems envisions a world where computation is not only everywhere, but is also attached to objects and users moving and interacting with the environment. For these mobile computing entities to communicate, wireless links should be evaluated, built and released in a dynamic, intelligent way. In this paper we analyze the specific case of mobile entities augmented with sensor and radio frequency identification (RFID) information. We propose a set of protocols for intelligent building of dynamic context networks, where node interactions are conditionally granted and a shared context is built with the information provided by collaborating entities.
