Patent Searching and Data


Title:
A system and a method of an alternative scan about an ad hoc network
Document Type and Number:
Japanese Patent JP6193394
Kind Code:
B2
Abstract:
Methods, devices, and computer program products for selective scanning of ad-hoc networks are described herein. In one aspect, a method includes receiving a message identifying a number of times the message has been forwarded. The method further includes selectively scanning for other ad-hoc networks based on the identified number. In one aspect, a root device for an ad-hoc network is responsible for generating synchronization messages for nodes of the ad-hoc network. The synchronization message includes a count of the number of times the synchronization message has been forwarded. When the hop count reaches a limit, the synchronization message is no longer retransmitted or forwarded by receiving nodes. Nodes receiving this message may recognize they are positioned near the edge of the ad-hoc network. In at least one embodiment, these nodes may selectively scan for other ad-hoc networks based on the hop count reaching or exceeding a predetermined threshold.
