Analytical modelling solution of producer mobility support scheme for named data networking

Abstract

Named Data Networking (NDN) is a clean-slate future Internet architecture proposed to support content mobility. However, content producer mobility is not supported fundamentally and faces many challenges such as, high handoff latency, signaling overhead cost and unnecessary Interest packet losses. Hence, many approaches indirection-based approach, mapping-based approach, locator-based approach and control/data plane-based approach were proposed to address these problems. Mapping-based and control/data plane-based approach deployed servers for name resolution serveces to provide optimal data path after handoff, but introduces high handoff latency and signalling overhead cost. Indirection-based and locator-based approach schemes provide normal handoff delay, but introduces sub-optimal or tiangular routing path. Therefore, there is needs to provide substantial producer mobility support that minimizes the handoff latency, signaling cost and improve data packets delivery via optimal path once a content producer relocates to new location. This paper proposed a scheme that provides optimal data path using mobility Interest packets and broadcasting strategy. Analytical investigation result shows that our proposed scheme outperforms existing approaches in terms of handoff latency, signaling cost and path optimization.

A Conceptual model of mixed-integer linear programming water distribution system

“…Traditionally, ideas can be developed into mathematical formulation to represents a model as proposed in [11], [12], [10] which is called a conceptual model. Moreover, as previous research used MILP to model WDS and combined it with DE to obtain the optimal solution, though they consider pipe size and inlet pressure as objective function [14].In this study, the MILP of WDS is formulated as a multiobjective optimization (MOO) problem to minimize pipe-line cost and the total head loss of the system, also maximize reliability of water production.…”

OPMSS: Optimal Producer Mobility Support Solution for Named Data Networking

“…Numerical evaluation is used, as in [49][50][51], for the handoff performance evaluation. However, the numerical evaluation only is not enough to cover the peculiarities of producer mobility.…”
