Self-Organizing Network (SON) mechanism comprises of three components of self-configuration, self-optimization and self-healing which can contribute to optimize the performance of the next generation broadband network such as the Long Term Evolution (LTE) networks. The aim of this study is to propose a self-organizing handover procedure based on the Self-Organizing Network (SON) concept for LTE network...
Vehicular Ad Hoc Network (VANET) is quite different from other ad hoc networks in term of functionality because of the variable node density, high node mobility, and unpredictable and harsh communication environment. There are two major applications VANET, namely safety applications and non-safety applications. In addition, network optimization is one way to maintain the existing protocols and other...
Collaborative beamforming with finite number of collaborating nodes produces sidelobes that depend on the nodes' arrangement. Sidelobes cause interference when they occur at the directions of unintended receivers and thus reduce the transmission rate at these receivers. Peak sidelobe minimization does not effectively minimize the overall sidelobe of a beampattern formed by collaborative beamforming...
This paper presents the significance of the application of Firefly Algorithm (FA) in the Linearly Constrained Minimum Variance (LCMV) beamforming technique. In this work, in order to obtain the best result, different amounts of parameters such as iteration, null and the boundary have been implemented for more than 30 times. This is done to improve the null steering, signal to interference plus noise...
Constructing a quality solution for the examination timetable problem is a difficult task. This paper presents a partial exam assignment approach with great deluge algorithm as the improvement mechanism in order to generate good quality timetable. In this approach, exams are ordered based on graph heuristics and only selected exams (partial exams) are scheduled first and then improved using great...
A future cellular network demands a new architecture that can facilitate the autonomous deployment of the infrastructure similar to Wi-Fi. A novel method of deploying a cellular network has been introduced with small cellular base stations, or femtocells, autonomously deployed by users in an underlay macro-cellular network. This autonomous cellular concept allows the network to grow in an organic...
