This paper studies security for data aggregation in sensor networks. Current aggregation schemes were designed without security in mind and there are easy attacks against them. We...
We investigate the preservation of quality of service guarantees to a flow of packets in the presence of flow aggregation. In flow aggregation, multiple flows, known as the consti...
