This paper describes the development of a very flexible multi-antenna testbed built on 5 PCBs. The FOM testbed (FOM, Flyable OFDM MIMO) was built with off-the-shelf components and can be configured with any number of ...

Dimensioning of mobile networks (e.g. 2G, 3G, WLAN etc.) is more or less restricted to the service area projection and wireless capacity formulation (calculation of number of base stations/access points (BSs/APs) required) ...

With the increasing dependence on wireless LANs (WLANs), businesses and educational institutions are becoming more concerned about network security. The latest WLAN security protocol, the IEEE 802.11i assures rigid security ...

In this paper we propose a protocol for periodical data collection applications in wireless sensor networks. The protocol is energy-aware in the sense that the way of energy consumption used here is evenly distributed. The ...

Power consumption is a crucial problem for energy-constrained ad hoc sensor networks. This paper proposes a new scheme called energy distributed algorithm to improve the energy efficiency of ad hoc sensor networks, in which ...

This paper outlines the implementation of collaborative beamforming to a remote low power wireless sensor network and presents its energy saving potential. The directivity procured from the beamforming allows power to be ...

This paper presents a new method to improve on block spread OFDM by exploiting time diversity to ensure that the blocks are independent and uncorrelated. Simulation results have shown significant improvement over conventional ...

Clustering has been used as an effective approach to saving energy and providing better scalability for Wireless Sensor Networks (WSN). Most of the existing methods for clustering use a star-based topology while the newly ...

Handoff performance is one of the important metrics in mobility management where frequent handoff can occur in single session and that may degrade the performance of TCP (Transmission Control Protocol) and UDP (User Datagram ...

The high cost associated with the rollout of 3G services encourages operators to share network infrastructure. Network sharing poses a new challenge in devising fair, efficient and Pareto optimal resource allocation ...
