— In this paper, we propose multiuser multiple-input multiple-ouput (MIMO) one- and two-way relaying protocols. Several wireless MIMO node pairs are establishing either unidirect...
—In this paper, we propose a new user authentication (UA) scheme based on one-time password (OTP) protocol using smart cards for home networks. The proposed scheme is to authenti...
Sensor network applications are generally characterized by long idle durations and intermittent communication patterns. The traffic loads are typically so low that overall idle d...
In this paper we investigate a practical routing solution for a new class of wireless sensor networks where any node can be mobile anytime. Assuming GPS-enabled sensor nodes we pro...
—The hot spot problem is a typical byproduct of the many-to-one traffic pattern that characterizes most wireless sensor networks: the nodes with the best channel to the sink are ...
