—It is well known that IEEE 802.11 provides a physical layer multirate capability and, hence, MAC layer mechanisms are needed to exploit this capability. Several solutions have b...
—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 ...
In this paper, we discuss key management challenges for seamless handovers across heterogeneous wireless networks. We focus on utilizing existing keying material from previous acc...
