Wireless sensor networks are often used to monitor and report the locations of moving objects. In light of storage in sensors, the wireless sensor network can be viewed as a distributed database for storing and retrieving the location information of objects. Many methods for the construction of the message-pruning trees have been studied to reduce the cost of updating databases and querying objects...
In this paper, we first propose a method, ABVCap, to construct a virtual coordinate system in a wireless sensor network. ABVCap assigns each node multiple 5-tuple virtual coordinates. Subsequently, we introduce a protocol, ABVCap routing, to route packets based on the ABVCap virtual coordinate system. ABVCap routing guarantees packet delivery without the computation and storage of the global topological...
