A Dissemination Protocol to Guarantee Data Accessibility within N-Hops for Wireless Sensor Networks
One of the major challenges of designing a dissemination protocol for Wireless Sensor Networks (WSNs) is energy efficiency. Flooding and SPIN, which are very well-known proactive ...

Fundamental scaling laws for energy-efficient storage and querying in wireless sensor networks
We use a constrained optimization framework to derive fundamental scaling laws for both unstructured sensor networks (which use blind sequential search for querying) and structure...

Cooperation Enforcement and Learning for Optimizing Packet Forwarding in Autonomous Wireless Networks
In wireless ad hoc networks, autonomous nodes are reluctant to forward others' packets because of the nodes' limited energy. However, such selfishness and noncooperation ...

Federated Search of Text-Based Digital Libraries in Hierarchical Peer-to-Peer Networks
Abstract. Peer-to-peer architectures are a potentially powerful model for developing large-scale networks of text-based digital libraries, but peer-to-peer networks have so far pro...
