In LTE systems, handovers have to be glitch free and very fast because, unlike earlier mobile communication technologies, it does not support soft handover but instead it supports only hard handover and this makes handover particularly challenging in LTE networks. This research aims to optimise handover in LTE networ…
Wireless sensor nodes serve as both sensing and routing devices which are generally employed to send data from the primary source node to the destination node (or sink node). There are distinct procedures that wireless sensor networks (WSN) takes when put into operation to route traffic leading to Cluster Head (CH) e…
The main basic components for selecting modulation technique are Bit Error Rate (BER) and Signal to Noise Ratio (SNR). This paper examined the performance of different modulation in Multiple Input and Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system. A model of 2 × 2 MIMO-OFDM has been d…
Quality of service (QoS) is a key performance indicator (KPI) that is used in determining the efficiency of telecommunication services rendered to end users. Accessibility, connection quality and retainability are major factors used in evaluating quality of service of a network provider. For consumers, it is expected…
Cognitive radio network (CRN), which has been adopted as a promising solution for optimization of the limited available radio-frequency spectrum, has two major drawbacks: Missed Detection (MD) and False Alarm (FA). This work proposed fuzzy-based intelligent resource allocation in cognitive radio network (FIRA-CRN) as…
Intermodulation interference occurs when transmitters are co-located as well as in nonlinearity of the signal processing during modulation. This distortion in nonlinear systems are not needed in radio signal processing because they generate unwanted spurious emissions which occupy the spectrum of the desired signal f…
Communication always attracts extensive research interest as it is a core part of modern communication technology. IEEE 802.11b has become common in recent years largely due to the advantage of user mobility, relatively low acquisition cost and ease of implementation making it common for both residential and business…
