CLUSTER HEAD ELECTION IN AN AD-HOC NETWORK

摘要

The ad-hoc network includes a plurality of mobile nodes including atleast one group of mobile nodes operating as a cluster with a currentlyelected clusterhead node. The mobile nodes include a controller and a wireless communicationsdevice cooperating therewith to determine whether the currently electedcluster headnode appears inactive and then initiate a token-based cluster head nodeelection basedthereon. During the token-based cluster head node election, the cluster mobilenodesgenerate and transmit tokens having respective token weights, receive tokensfromneighboring nodes, selectively retransmit the tokens based upon the tokenweights,and elect a new cluster head node based upon the token weights.
