The Fast Handover for Mobile IPv6 (FMIPv6) [2] aims at reducing the long handover latency in Mobile IPv6 [1] by fast movement detection and fast binding update. Furthermore, it al...
The GSM network with the greatest worldwide number of users, succumbs to several security vulnerabilities. The Short Message Service (SMS) is one of its superior and well-tried se...
The present paper presents a Markov Chain model of polling in noisy multi-hop systems typical of Power Line Communications (PLC) as well as of other systems. The model includes the...
With MBMS, a mobile Terminal (MT) that is on the move and receive an MBMS service may have to handover from a Common to a Dedicated Channel when crossing the cell’s edge. In pre...
Wireless IEEE 802.11 networks are typically deployed as a convenient and flexible way to access wired backbones. However, due to the inherently shared nature and physical propert...
