Wireless Sensor Networks (WSNs) have been widely deployed in many fields and commonly adopted in many applications. There are several routing protocols for WSNs, such as Ad hoc On-Demand Distance Vector Routing (AODV) and Sensor Protocols for Information via Negotiation (SPIN). However, one major problem of these routing protocols is that they cannot provide a global view for network topologies, as...
Wireless sensor networks (WSNs) have become widely used because of their low cost and low power consumption. With the IPv6 Low-power Wireless Personal Area Network (6LoWPAN) standard proposed by Internet Engineering Task Force (IETF), WSNs can be seamlessly integrated with Internet devices running IPv6. With 6LoWPAN, it will be easy to manage a lot of sensors via the Internet by many existing network...
The Public Switched Telephone Network (PSTN) is the oldest and largest telecommunications network in existence. The auto call-transfer function is one of the basic services supported by PSTN that switches incoming calls to the subscriber. It is likely for the subscribers to lose incoming calls when they leave the room. Therefore, we propose a ZigBee location-awareness and tag identification technique...
