Abstract:

A voting mechanism based broadcast authentication scheme for the mobile sensor networks is presented. The identity of the broadcast is verified and voted by nodes within the communication range to be authenticated. If the number of pros surpasses threshold <em>T_</em>1, the node passes the authentication and joins the network. When the node moves, the mentioned above is used to assist authenticating. If the number of pros surpasses threshold <em>T_</em>2, the node passes the authentication. Simulation shows that as long as security is assured during the authentication process, the proposed program requires less communication traffic thus consumes less energy than the three compared methods, the proposed method performs well on storage consumption with low-consumption.

Key words: wireless sensor networks, broadcasting authentication, voting mechanism
