Complex Queries in P2P Networks with Resource-Constrained Devices

Complex Queries in P2P Networks with Resource-Constrained Devices

Structured Peer-to-Peer (P2P) systems are increasingly important for scalable data dissemination and search. At the same time, the importance of mobile devices like smartphones, PDAs, and netbooks for accessing and storing data is rapidly increasing. Current distributed approaches for resolving complex search queries, like multi-attribute and range queries, typically require multiple messages t...

Constrained Consumable Resource Allocation in Uncertain Project Networks with Fuzzy Activity Duration

Answering Constrained k-NN Queries in Unstructured P2P Systems

The processing of k-NN queries has been studied extensively both in a centralized computing environment and in a structured P2P environment. However, the problem over an unstructured P2P system is not well studied despite of their popularity. Communication-efficient processing of k-NN queries in such an environment is a unique challenge due to the distribution, dynamics and large scale of the s...

Complex Event Detection in Extremely Resource-Constrained Wireless Sensor Networks

Complex Events are sequences of sensor measurements indicating interesting or unusual activity in the monitored process. Such events are ubiquitous in a wide range of Wireless Sensor Network (WSN) applications, yet there does not exist a common mechanism that addresses both the considerable constraints of WSNs and the specific properties of Complex Events. We argue that Complex Events cannot be...

A Unified Construction Method of P2P Networks with Lower Bound to Support Complex Queries

The topological properties of overlay networks are critical for the performance of peer-to-peer (P2P) systems. The size of routing table and the diameter are among the most important parameters which measure the autonomy, efficiency, robustness and load balancing of P2Ps. In order to improve the four features for structured P2P networks, researchers have proposed many optimal designs with desir...
