In this paper, the problem of scrambling code (SC) planning and optimization in 3G networks is addressed. Scrambling Codes are used to identify and distinguish cells from one another in WCDMA networks. These SCs are reported by the mobile users to the network to declare which cells they are able to connect to. Under the limitation of available SCs to be assigned to the cells we propose various allocation...
Wireless Sensor Network (WSN) is a network of portable and lightweight sensors used to monitor a specific field and report the data they detect wirelessly to a sink node responsible for the analysis and decision making. WSNs have limited power as well as resources. More advanced sensors known as "multimodal sensors" can report more than one feature, which requires even more efficient utilization...
In this paper, we explore different sensor deployment problems and how these problems can be solved optimally using the current packing approaches in terms of small-scale problems. In addition, we consider the deployment of either homogenous or heterogeneous sensing devices. The deployment objectives are to maximize the coverage of the monitored field and use the best of the sensing devices characteristics...
