An architecture for wireless communication between control centers and registered users in emergency situations when the cellular network is not operational is described. It is based on delay tolerant networks (DTN) and enables mobile users with multiple radio interface technologies to communicate across heterogeneous network technologies. With the help of asynchronous bundles passing from hop to...
To achieve high data rates and seamless coverage, radio access networks continue to increase in complexity, and the expenditure on operational tasks continues to rise to unprecedented levels. The development of Long Term Evolution (LTE) with Self-organizing network (SON) functions is being considered as an effective way to tackle these challenges. The paper describes an approach to model the coverage...
Recent developments in mobile networks have looked at placing more autonomy and intelligence at base stations to encourage cooperation between them using a distributed approach in order to try and develop a network more robust to attacks and failures. A real time fully distributed algorithm that would allow base stations in cellular networks to autonomously and cooperatively find the wireless coverage...
This paper examines the issues of traffic load balancing in wideband code division multiple access (WCDMA) mobile communication networks through applying dynamic radio coverage. Dynamic radio coverage is achieved by adjusting radiation patterns of antenna arrays and the optimization of coverage is carried out cooperatively between cells using dedicatedly designed algorithm. In comparison with previous...
