The deployment of small cell base stations within the coverage area of a macrocell base station serves as an important means of increasing energy efficiency. Furthermore, such a deployment also constitutes a key technology for future communication network markets. There is a shortage of research, however, on how to efficiently solve the problem of coverage holes (that is, specific locations or areas...
Energy minimization has been one of the major research challenges for access networks striving for green communication. Macrocell base stations (MBSs) are the main contributors to energy consumption, and the situation has become worse as more MBSs are being deployed to cope with the ever-increasing data traffic. Therefore, it will be crucial in the near future to minimize the energy consumption of...
Due to the fact that existing 3.5G network cards usually select networks with the highest data rate as their priority choices, the radio resources may not be efficiently and equally utilized in a multiple network environment, even when the network with the highest rate is already congested. In this paper, we propose two dynamic resource allocation algorithms to resolve such issues assuming an HSPA...
As heterogeneous wireless sensor networks (WSNs) are being widely deployed for various applications, we are faced with a new challenge of network management for heterogeneous WSNs. On one hand, current available WSN management tools are either application specific, or platform specific, thus suffering from the lack of reusability in heterogeneous WSNs management environment. On the other hand, to...
