Ad hoc low-power wireless networks are an exciting research direction in sensing and pervasive computing. .. . Prior security work in this area has focused primarily on denial of communication at the routing or medium access control levels. . SINKS. Acknowledgement. Xiujuan. Yi (xyi@uci.edu). . Malini. .
