Reliable Seamless Handoff across Heterogeneous Networks based on Location aware M-PROMETHEE Method

摘要

A Mobile Terminal may undergo signal inconsistencies based on the contextual dependency. Context dependencies include location identification, mobility, rate of change of data in motion, velocity of the mobile device etc.. The frequency reuse is the main feature for augmenting the coverage area of a base station or access point and to improve the capacity of a mobile terminal. These are the main criteria that must support preventing any handoff failures which occur in a mobile terminal. Presently Seamless Mobility is the main concern. For overcoming the signal paucity in certain areas, the option of heterogeneous networks integration is the solution. In this Paper, we have implemented a Reliable Seamless Handoff Solution that comprises of a novel MADM method known as Modified Preference Ranking Organisation Method for Enrichment Evaluations (M-PROMETHEE) which is compared with the traditional Preference Ranking Organisation Method for Enrichment Evaluations (PROMETHEE) method. M-PROMETHEE results show satisfactory improvement over the conventional PROMETHEE method. Parameters used here include Data rates, Packet loss, Velocity, Bandwidth, Dwell Time and Jitter.
