Abstract - The Third Generation Partnership Project (3GPP) has proposed enhanced Inter-Cell Interference Coordination (eICIC) for the Fourth Generation Cellular Network Standard of the Heterogeneous Networks (HetNets) in order to decrease Cross-Tier Interference. eICIC includes two schemes, Cell Range Expansion (CRE) and Almost Blank Subframe (ABS). The Fourth Cellular Network Standard LTE (Long Term Evolution) and LTE-Advanced have high transmission rate and low delay. They are important standards of current cellular networks. In areas that have bad wireless signals, signal breaking can happen very frequently. To set up some low-power small cells is a way of compensating the bad signals. How to effectively install small cells to increase overall transmission rate in HetNets becomes an important issue for LTE-Advanced standard. This paper presents two dimensional cross-tier interference avoidance scheme on the basis of eICIC. The proposed scheme allows macro cell to reserve the frequency band that has better transmission performance and pico cell to exclude the frequency band that has worse transmission rate so as to improve the User Equipments (UE) transmission quality and performance. |

Abstract - Any type of computer network, a wireless network to connect network nodes uses wireless data connection. Wireless networking are a way by which the houses, telecommunication network and enterprise (business) started in a building wiring installations to avoid costly process, or as a connection between various devices in places. Within a relatively small area of wireless personal area network interconnect devices within reach of a person is usually. For example, both Bluetooth radios and a laptop for an invisible infrared light provides a headset each. ZigBee are also supports application. General Wi-Fi (2010) is becoming as a variety of consumer electronic device designers to integrate Wi- Fi start. A hacker is someone who exploits and vulnerabilities within a computer network or computer system is looking for. Such a hacker gain, as opposed to the challenge or can be induced by a multitude of reasons. Everywhere that often underground hackers group has evolved and these days they are well known in the community known as computers. |

Abstract - In this paper, we address two challenging issues underlying spatial simulation using software agents immersed in Virtual Geographic Environments (VGE). First, the way to describe virtual VGE models using accurate spatial decomposition approaches structured using graph theory techniques. Second, the use of graph abstraction techniques to support realistic and advanced navigation and path planning capabilities for software agents considering the VGEs characteristics. In order to illustrate our contributions to the growing field of spatial simulations, we present and discuss a case study involving an urban VGE model populated with agents who autonomously and differently interact with multiple abstractions of the same physical environment. |
