In this paper, a new scheme is proposed to allow the correspondent node to recognize the handover situation of the mobile node for vertical handovers using Mobile IPv6 signaling. The proposed scheme might be helpful for quick adjusting real-time traffics between two nodes when a drastic change in a bandwidth occurs due to vertical handovers in heterogeneous access networks that have a quite dif...

Laser-induced ultrafast demagnetization has puzzled researchers around the world for over two decades. Intrinsic complexity in electronic, magnetic, and phononic subsystems is difficult to understand microscopically. So far it not possible explain using a single mechanism, which suggests crucial piece of information still missing. In this paper, we return fundamental aspect physics: spin its ch...
