Performance evaluation of mobile IPv6 handover extensions in an IEEE 802.11b wireless network environment
(2006)In order to support mobile users, the basic Internet protocols have been extended with protocols (e.g., Mobile IPv6) for intercepting and forwarding packets to a mobile and possibly roaming node. Seamless roaming requires ...

Stochastic differential equations for modeling, estimation and identification of mobile-to-mobile communication channels
(2009)Mobile-to-mobile networks are characterized by node mobility that makes the propagation environment time varying and subject to fading. As a consequence, the statistical characteristics of the received signal vary continuously, ...

The wireless control network: Monitoring for malicious behavior
(2010)We consider the problem of stabilizing a plant with a network of resource constrained wireless nodes. In a companion paper, we developed a protocol where each node repeatedly transmits an appropriate (stabilizing) linear ...
