A large-scale clustered massive MIMO network is proposed for improving the spectral efficiency of next-generation wireless infrastructure by maximizing its sum-rate. Our solution combines advantages centralized processing architecture and MIMO. Explicitly, divided into multiple clusters; each cluster handled a unit, which connects to certain number MIMO-aided BSs, where only limited information...

Travel time information is a vital component of many intelligent transportation systems (ITS) applications. In recent years, the number of passengers travels in train & number of trains in India has increased tremendously. Due to the increase in number of trains the train times may be delayed and the passengers have to wait at railway stations. A desirable strategy to deal with such issues is t...

We address a dynamic covering location problem of an Unmanned Aerial Vehicle Base Station (UAV-BS), where the sequence single UAV-BS in wireless communication network is determined to satisfy data demand arising from ground users. This especially relevant context smart grid and disaster relief. The vertical movement ability non-convex functions restrict utilizing classical planar approaches. Th...

False Base Stations attack raises concerns about data privacy during handover process in 5G networks. Broadcasting of measurement reports unveils the need security assessment since a false base station can send stronger signal to User Equipment (UE) establish connection with itself. This may cause leakage information. Thus, fundamental solution is protect encryption algorithms. In this paper, w...

Mobile communication is more vulnerable to security attacks such as interception and unauthorized access than xed network communication. To overcome these problems, many protocols have been proposed to provide a secure channel between a mobile station and a base station. However, the public-key based protocols are not fully utilized due to the poor computing power and the small battery capacity...
