Tiivistelmä (eng): | The past decade has seen a vast growth in wireless communication, continuously fuelled by the users' ever-increasing demand for higher data rates. Various technologies are constantly competing with each other, trying to establish supremacy over other concurrent technologies and desperately vying to make its own space in the field of telecommunication. With the advent of 4G systems, we are at a crucial juncture. The all-important question has become: how to provide ubiquitous coverage for all the users in the network in a cost-efficient manner while at the same time satisfy high data rates and the Quality of Service (QoS) requirements proposed by ITU-R for IMT-Advanced systems? One technology which can provide an answer to the above question is low power home base stations called femtocells used for local area deployments such as residences, apartment complexes, offices, business centres and outdoor hotspot scenarios. Through this work, we propose a scalable and fully distributed solution called the Distributed Capacity Based Channel Allocation Algorithm to overcome the problem of interference management and efficient system operation in a local area environment. The proposed scheme is simple yet robust and helps Home eNodeBs select the best available radio resources which minimizes interference to the neighbouring nodes. Further, the scheme is subjected to various mitigating circumstances and interference-limited scenarios. The performance evaluation of the scheme is done under such conditions to ensure that it is scalable, flexible and can be considered as a practically viable option. Through this work, we try to not just improve the throughput experienced by the average user in a cell, but also the ones at the cell-edge who su_ers the most due to interference from the neighboring cells. The scheme proposed aims to be energy-e_cient as well by reducing the total number of component carriers used by each HeNB without compromising the average cell throughput values. |
