Performance analysis of opportunistic broadcast for delay-tolerant wireless sensor networks
This paper investigates a class of mobile wireless sensor networks that are unconnected most of the times; we refer to them as delay–tolerant wireless sensor networks (DTWSN). T...

On neighbor discovery in wireless networks with directional antennas
We consider the problem of neighbor discovery in static wireless ad hoc networks with directional antennas. We propose several probabilistic algorithms in which nodes perform rand...

Revisiting neighbor discovery with interferences consideration
In wireless multi-hop networks, hello protocols for neighbor discovery are a basic service offered by the networking stack. However, their study usually rely on rather simplistic...
