AN OPTIMIZED VERTICAL HANDOFF DECISION STRATEGY USING GENETIC ALGORITHM IN HETEROGENEOUS WIRELESS NETWORKS

Mrs. Chandralekha and Dr. Prafulla Kumar Behera

Next generation wireless network is envisioned as a convergence of different wireless access technologies that can be transformed into seamless communication environments through application of context-based handovers. Designing of error-free and fast-handoff support techniques in heterogeneous wireless environment is a challenging issue. To manage the ABC (Always best connected) requirement, various vertical handover decision strategies have been proposed in the literature using advanced tools and concepts. In this paper we have proposed a multi criteria vertical handoff decision algorithm which will select the best available network with optimized parameter value in heterogeneous wireless environment. The neural network and genetic algorithm tool has been used to implement and process and optimize the multi-criteria vertical handoff decision metrics.
