	abstract        = {Large path losses of millimeter waves restrain the acceptance of 60
	GHz technology in future networks. Directional antennas can be exploited
	in 60 GHz networks to mitigate the detrimental impact of fading.
	Employing fully directional antennas complicates the neighbor discovery
	process where each sector must be probed individually to discover
	neighbors located in that sector. In random scanning strategy, nodes
	select to-be-scanned sector randomly. In this letter, we analyze
	the minimum number of random sector scanning attempts during neighbor
	discovery process to have a non-isolated network. We present an analytical
	model to study the isolation probability defined as probability of
	having at least one isolated node in the network. Based on the isolation
	probability, we derive the minimum number of sector scanning attempts
	in a 60 GHz ad hoc network with arbitrary number of nodes. Although
	60 GHz directional network is studied, this analysis is applicable
	to any directional wireless network.}
