Abstract— This paper considers designing in the minimax sense complementary low-pass/high-pass approximately linear-phase recursive filters with variable magnitude characteristi...
— In this paper, we investigate the adaptive resource allocation problem in multiuser multihop OFDM systems. Assuming that base station(BS) knows all channel information, we form...
The continuing miniaturization of technology coupled with wireless networks has made it feasible to physically embed sensor network systems into the environment. Sensor net proces...
Recent years have witnessed a growing interest in the application of wireless sensor networks in unattended environments. Nodes in such applications are equipped with limited ener...
Trust management model that we present is adapted for ubiquitous devices cooperation, rather than for classic client-supplier relationship. We use fuzzy numbers to represent trust...
