—In this paper we study the performance of the Heuristic Localized Gradient Algorithm (HLGA) that was designed for uplink scheduling in 3G long term evolution (LTE) systems. The performance of the algorithm is examined when dynamic traffic models are assumed. With dynamic traffic, users will have different buffer occupancies. The amount of resources granted(More)
The protected-subframe (PSF) structure is one of the methods for downlink inter-cell interference coordination (ICIC) utilized in heterogenous networks and is featured in Rel-10 of the technical specification for 3GPP's E-UTRAN. Static configuration of PSF has proven to increase performance but the dynamic configuration is yet to be examined. In this paper,(More)
In this paper, we study the strategic coexistence of macro and pico cells and investigate a utility based resource allocation technique for heterogeneous networks. Aiming at finding an objective driven allocation of resources, we focus on time domain inter-cell interference coordination (ICIC) techniques. Macro and pico cells optimally select their almost(More)
In this paper we propose a simple design and implementation of an intelligent robot that can be used to handle security breaches. Applications may include counter terrorism, handling pollution crises, monitoring for security purpose, etc. Ultrasound sensors, temperature sensors, GPS devices, and wireless cameras are mounted on the robot in order to give 360(More)
