Relay based cellular network (RBCN) is a kind of hybrid cellular network working under OFDMA technology. It is a promising network to support high transmitting data-rate, throughput, capacity, flexibility and resource efficiency. Normally QoS offered to mobile user (MS) is improved in RBCN by using relay station (RS) to enhance Base station (BS) radio coverage. But in reality, QoS is affected by service...
Call Admission Control (CAC) is one of the most important parts in radio resource management of the wireless networks and it has a huge impact on the quality of service (QoS).Traditional CAC strategies focus on increasing the radio resource utility by decreasing the service blocking probabilities. In this paper, a new CAC scheme based on game theory is introduced to analyze the conflicts and rewards...
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...
The increasing popularity of wireless communications and the different QoS requirements of new types of service lead to higher demands on cellular mobile networks. With central control and multi-hop communication, relay based cellular networks are seen as an effective way to meet users' increased bit rate requirements while still retaining the benefits of a cellular structure. However, the more complex...
Increasing popularity and higher data requirements of new types of service result in higher demand in wireless networks. Hybrid cellular networks have been seen as an effective way to meet the users' increased bit rate requirements while still retaining the benefits of a cellular structure. The objective of this paper is to propose and illustrate effective and efficient approaches for improving the...
A real time fully distributed algorithm that would allow base stations (BSs) in cellular networks to autonomously and cooperatively find the wireless coverage pattern to optimize network performance is described. An antenna system that can change the radio frequency (RF) coverage is assumed at each base station. Simulations based on mobile WiMAX technology show the effectiveness and robustness of...
