We present the design and implementation of UDAE, a universal data access engine for wireless sensor networks. The UDAE allows developers to access data both locally and over the network from a variety of sources, such as sensors, communications links and platform components in a unified manner. It is also fully extensible, allowing data sources and users to be added flexibly at run-time. This enables...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
