“…The application of smart antennas in wireless network has also been widely investigated. However most work related to traffic load balancing only focuses on different radio channel allocation schemes and most work on smart antennas [1] only consider the radio propagation channels within one cell. These severely limit their efficiency.…”

“…It can be used to improve performance for any distributed system containing nonuniformly distributed traffic, especially for resolving the traffic hot spots. Studies on dynamic sectorisation, use of tilted antennas [1] and dynamic cell size control (cell breathing) [2] [4] have shown that the system performance can be improved by balancing non-uniformly distributed load. Increasingly, web services are provided by massive, geographically diverse "Internet-scale" distributed systems, some having several data centers each with hundreds of thousands of servers.…”

Energy consumption in an efficient way for data centers and mobile network is an important social, economical problem. This paper concentrates on the feasibility energy consumption in mobile network system by improving the load calculation, resource allocation and access techniques. We perform a efficiency based study to evaluate three issues related with energy consumption: the impact of hot spot load balancing, role of signal switch on-off system and proper resource allocation. Our results highlight that hot spot load balancing can significantly reduce the required energy more efficiently with the help of resource allocation and access in an efficient manner. Further, our results show that signal transmitter switch on-off can be useful, especially in combination with hot spot load balancing, and an optimized coverage area calculation. This paper proposes a new Load Balancing technique in congested area through appropriate access point selection and proper cell shaping. This paper proposes new Access Point Architecture with two types of access points; one is programmable Intelligent Access Point (IAP) that can control multiple Conventional Access Point (CAP). This paper will also minimize the no service area problem. The proposed approach is evaluated with repulsion factors which occur due to un served area in a cell area. This paper also proposes solutions for different types of load, e.g. static load, dynamic load. Static load is fixed but Dynamic load is due to some moving user concentrations. The proposed algorithm is co operative in nature, so that the neighboring access points of a particular access point will get information from their neighbors. Through this new concept we have seen performance improvement as well as efficient resource utilization.

“…Furthermore, in [8][9][10], optimum tilting was treated in view of the BS antenna characteristics, the cells sectorization, the site spacing, the number of signal paths, and the traffic volume showing that optimum tilting depends on various network parameters. Finally, in [11], an adaptive tilting method was proposed for interference mitigation and capacity enhancement in WCDMA systems, revealing the importance of beam tilting in wireless communications.…”

Recommended by A. PanagopoulosBase station antenna downtilt mitigates interference and improves the downlink performance of wireless systems. A semistochastic propagation model is presented and applied to the study of the impact of the base station beam tilting in cellular communications. The two-ray approximation of the proposed model is described analytically. Beam tilting is evaluated in relation to the base station antenna radiation pattern, the antennas height, the propagation environment, the bit error rate, and the signalto-noise ratio at the receiver front end. Analytically derived expressions for the fading envelopes, the error probability, the optimum tilting angle, and the downlink capacity of a WCDMA system are derived. Theoretical analysis and simulation results are provided to show the characteristics of the model. Comparisons with data in the literature confirm its validity. Furthermore, the effect of beam tilting on system downlink performance in terms of bit error rate and capacity is investigated.

This article surveys the literature over the period of the last decade on the emerging field of self organisation as applied to wireless cellular communication networks. Self organisation has been extensively studied and applied in adhoc networks, wireless sensor networks and autonomic computer networks; however in the context of wireless cellular networks, this is the first attempt to put in perspective the various efforts in form of a tutorial/survey. We provide a comprehensive survey of the existing literature, projects and standards in self organising cellular networks. Additionally, we also aim to present a clear understanding of this active research area, identifying a clear taxonomy and guidelines for design of self organising mechanisms. We compare strength and weakness of existing solutions and highlight the key research areas for further development. This paper serves as a guide and a starting point for anyone willing to delve into research on self organisation in wireless cellular communication networks.
