Analysis of TTL-Based Consistency in Unstructured Peer-to-Peer Networks
TL;DR: A tradeoff between search performance and freshness is indicated: the search cost decreases sublinearly with decreasing freshness of P2P content sharing under TTL-based consistency.
Journal ArticleDOI
An overview of pervasive computing
TL;DR: The importance of pervasive computing is rapidly increasing with the current trend toward universal presence of mobile computing, computer networks, and wireless communications ineveryday life.

On Social-Temporal Group Query with Acquaintance Constraint
TL;DR: Two efficient algorithms are proposed, SGSelect and STGSelect, which include effective pruning techniques and employ the idea of pivot time slots to substantially reduce the running time, for finding the optimal solutions to the social-temporal group query.
