Recently, the concept of locality-aware predicates (LAP) has been proposed. A LAP models a predicate within a local region of the whole network in a large-scale locality driven system, such as WSNs and modular robotics. In such systems, the cost of doing a global predicate detection is high, besides which, a predicate over the state of a local region better captures properties of local interactions...
In large-scale networks where a continuously on-going monitoring program is needed, using traditional predicate detection algorithms might cause the system to have a single point of failure. This paper presents an on-line distributed algorithm that detects strong conjunctive predicates and we show that it is resilient to node failures. Our algorithm assumes a pre-constructed spanning tree in the system,...
