Load balancing with offloading algoritm for xG heterogeneous wireless cellular network

摘要

The ever growing mobile data traffic, due to increasing data demand of increasing number of users, has motivated researchers to analyze performance of next generation heterogeneous wireless network (xGHWnet). The xGHWnet consists of micro base station (mBS) of Long Term Evolution (LTE) or Long Term Evolution-Advanced (LTE-advanced) mobile cellular network and pico hotpot(s) to cover dead zone or number of coverage zone. A handoff algorithm has been proposed to balance the traffic load of LTE and LTE-Advanced and then improving the overall capacity. An offloading algorithm has also been introduced to reduce computation latency and power consumption. Fractional Frequency Reuse (FFR) is used to improve the channel utilization and reduce interference. The performance of the proposed system has been evaluated using MATLAB Simulation. It has been found that the proposed system outperforms traditional system.
