ADAPTIVE, ASYNCHRONOUS RENDEZVOUS PROTOCOL FOR OPPORTUNISTIC NETWORKS, AND PORTABLE COMMUNICATION DEVICE USING IT

摘要

The present invention relates to a method for discovering a neighbor node using an adaptive and asynchronous rendezvous protocol in an opportunistic network and a portable communication device using the same, the method for discovering a neighbor node includes: a step that each of nodes in the opportunistic network selects a primary number (p) greater than 2; a step that the each of nodes generates a wake-up pattern using the selected primary number; and a step that the each of nodes discovers a neighbor node according to the generated wake-up pattern. According to the present invention, the method is adaptive to requirements such as its own energy state and delay, has no necessity to be synchronized with neighbor nodes, is capable of discovering a neighbor node with the minimum discovery energy and is capable of saving energy for discovering.
