Sensor Networks will soon become ubiquitous, making them essential tools for monitoring the activity and evolution of our surrounding environment. However such environments are expected to generate vast amounts of temporal ...

Flash memory is the most prevalent storage medium found on modern wireless sensor devices (WSDs). In this article we present two external memory index structures for the efficient retrieval of records stored on the local ...

An important problem in unstructured peer-to-peer (P2P) networks is the efficient content-based retrieval of documents shared by other peers. However, existing searching mechanisms are not scaling well because they are ...

An important challenge in peer-to-peer (P2P) networks is to efficiently search the contents of other peers. The authors survey existing search techniques for information retrieval in P2P networks, including recent techniques ...

We initiate a study on the effect of the network topology on the performance of Peer-to-Peer (P2P) information retrieval systems. The emerging P2P model has become a very powerful and attractive paradigm for developing ...

Overlay networks are application layer systems which facilitate users in performing distributed functions such as searches over the contents of other users. An important problem in such networks is that the connections ...

The advances in wireless communications along with the exponential growth of transistors per integrated circuit lead to a rapid evolution of Wireless Sensor Devices (WSDs), that can be used for monitoring environmental ...
