Delay/Disruption‐Tolerant Mobile RFID Networks: Challenges and Opportunities
Hongyi Wu, Zhipeng Yang · 2010
This chapter presents the latest research that deals with a Featherlight Information Network with Delay-Endurable RFID Support (FINDERS), composed of passive RFID tags which are ultra light, durable, and flexible, without power supply for long-lasting applications. It investigates the use of RFID gear for wireless network construction, aiming to find events of interest and gather aggregate information. The chapter remains an open issue to design most appropriate protocols for FINDERS, which faces unprecedented challenges in communication and networking, due to its sporadic wireless links, unique asymmetric communication paradigm, intermittent computation capability, and extremely small memory of tags. Several issues in protocol design including routing metrics, queue management, and duplication control must be carefully addressed. Furthermore, testbed implementation and experiments need to be carried out to investigate practical problems due to unreliable and asymmetric RFID communications and develop corresponding solutions.
