Wireless sensor network applications, similarly to other distributed systems, often require a scalable time synchronization service enabling data consistency and coordination. Thi...
Sketches--data structures for probabilistic, duplicate insensitive counting--are central building blocks of a number of recently proposed network protocols, for example in the con...
Flooding in wireless ad hoc networks is a fundamental and critical operation in supporting various applications and protocols. However, the traditional flooding scheme generates ex...
