Wireless Sensor Network (WSN) which is capable of sensing, storing data, processing data and transmitting data has been widely applied in providing effective surveillance. Optimum sensor node placement in the surveillance area is needed since the number of sensor nodes that can be deployed are limited. The positions of sensor nodes must be able to provide maximum coverage with a longer lifetime. This...
Delivery of broadband telecommunication services in specific environments is often more easily realized by wireless systems than by roll out of cable networks. However, mobile and wireless broadband connectivity traditionally is also associated with extensive planning efforts and large investments. Wireless mesh network (WMN) technology, which is typically known for low infrastructure cost, rapid...
In this paper we present system modeling for HSPA networks, and the design and implementation of an ns-3 simulator for HSPA performance assessment. As a case study, the system model and simulator are integrated in the context of providing energy-saving solutions in cellular networks. Our simulator is a highly modular and scalable for studying how a given infrastructure deployment solution, along with...
The aim of this paper is to evaluate the throughput performance of IEEE802.11n WLANs using a well-known commercial simulator called OPNET Modeler. We study the effects of IP packet size, Modulation and Coding Scheme (MCS), Channel Bonding, number of MIMO spatial streams, Block Acknowledgement (BA) and Type of Service (ToS)/Access Category (AC) on maximum throughput and Throughput Efficiency (TE)....
