Adaptive Load Balancing Handoff Scheme for Heterogeneous Wireless Network

Recent day development of wireless technology integrates to communicate with each other. A handoff scheme is essential to continue connections whenever a mobile node moves from one coverage area of network to another. The handoff management issues consist of finding the appropriate time to perform the handoff, velocity, channel conditions, cost, bandwidth and RSS etc., In this paper, we propose a vertical handoff decision algorithm for heterogeneous wireless network based on the Velocity of mobile node and the Adaptive traffic load balanced handoff management scheme which adaptively control the handoff time according to the load status of cells. The algorithm considers the number of handoff when the velocity increases with effective reduction of probability of handoff and efficiently manages further overloaded traffic in the system. Simulation result shows that the effectiveness of the proposed algorithm during handover between different wireless networks.
