Hussain chains revisited

Haider N. Hussain

Proxy Mobile IPv6 (PMIPv6) was proposed by the Internet Engineering Task Force (IETF) as a new network-based mobility protocol which does not require the involvement of MN’s in any form of mobility management. MN can handover relatively faster in PMIPv6 than in host-based mobility protocols (e.g. Mobile IPv6 (MIPv6)) because it actively uses link-layer attachment information which reduces the m...

Value Chains: Production Upstreamness and Downstreamness Revisited

Measures devised to quantify production upstreamness and downstreamness in value chains have been introduced and used increasingly in recent years. While the constructs embodied in these measures are meaningful, this paper identifies an overlooked implementation problem. Specifically, the algorithms have been applied either as though the underlying data represent flows, or under the assumption ...

Niazi & Hussain, Sensing Emergence in Complex Systems

We propose the Sensing of Emergent behavior in a Complex Adaptive System (SECAS), an extension of our previous work Formal Agent Based Simulation Framework (FABS). Using aggregated data from an array of proximity sensors, SECAS allows for the detection of complex behavior such as flocking of mobile robots or life forms. For validation, we develop an agentbased simulation model. Extensive simula...

QUICKSELECT Revisited

We give an overview of the running time analysis of the random divide-and-conquer algorithm FIND or QUICKSELECT. The results concern moments, distribution of FIND’s running time, the limiting distribution, a stochastic bound and the key: a stochastic fixed point equation.
