Mobility Load Balancing (MLB) is a common technique to deal with the uneven traffic distribution in mobile networks. The aim of MLB is to alleviate congestion problems by sharing traffic demand among neighbor cells through the modification of handover parameters. MLB has been successfully used in legacy radio access technologies. However, in Long Term Evolution […]
Read moreTelecommunication networks often face power outage problems in the natural disaster affected areas. Also, owing to a sudden substantial increase in network traffic loads the battery backup power of the base stations run out quickly and therefore hampering telecommunication services. To overcome this system performance issues, we propose a Long Term Evolution (LTE)-Advanced (LTE-A)-based user […]
Read moreWBAN scan play vital role in medical diagnosis and preventive medical treatment to a next level. So far lots of independent miniature sensors are being used to monitor and record vital patient readings. These miniature sensors can also be installed on human body to form WBAN, so as to assimilate group readings and form more comprehensive information […]
Read moreThis paper deals with the problem of synchronization in networks of heterogeneous agents with common nominal behavior. The agents are modeled as (possibly nonlinear) perturbed versions of a common SISO nominal LTI operator, and they are interconnected via a sparse memoryless interconnection operator, coherent with the communication graph underlying the network. The network is said […]

Regional ACO-Based Cascaded Adaptive Routing for Traffic Balancing in Mesh-Based Network-on-Chip Systems
The regular topology of mesh-based network-on-chip (NoC) provides flexible and scalable architecture for chip multiprocessor (CMP) systems. However, as the complexity of network increases, routing problems become performance bottlenecks. In the field of wide area networks (WANs), ant colony optimization (ACO) has been applied to an adaptive routing for improving performance and achieving load balancing. […]
Read moreRecently, the way people consume video content has been undergoing a dramatic change. Plain TV sets, that have been the center of home entertainment for a long time, are losing grounds to Hybrid TV’s, PC’s, game consoles, and, more recently, mobile devices such as tablets and smartphones. The new predominant paradigm is: watch what I […]
Read moreTo be successful in the 21st century, students must have a fundamental knowledge of complex networks which allows them to explore the interconnectedness of our world. Network science, a relatively new field of study, represents a fundamental shift away from reductionism to a more complex real world approach to problem solving which looks at interactions between […]
Read moreUltra-low-power design has been a challenging area for design of the sensor front-ends especially in the area of Wireless Body Sensor Nodes (WBSN), where a limited amount of power budget and hardware resources are available. Since introduction of Compressed Sensing, there has been a challenge to design CS-based low-power readout devices for different applications and among all for biomedical signals. Till now, […]
Read moreIn this paper, we investigate a distributed beamforming problem to optimize energy efficiency (EE) in ultra-wideband (UWB) based implant body area networks (IBANs). To evaluate the impact of relay location on the EE, a relay location based cooperative network model is proposed, where multiple on-body relays are employed to assist an implant node to communicate with a BAN coordinator. With the proposed […]

Performance of uplink joint reception CoMP with antenna selection for reducing complexity in LTE-A systems
Coordinated Multi-point (CoMP) transmission and reception is considered as a promising technique to combat inter-cell interference, enhance throughput, improve mobility, reduce handover interruption time, and also to increase spectrum efficiency. In this paper, we investigate and analyze the performance of uplink intra-site joint reception CoMP (JR-CoMP) for LTE-Advanced (LTE-A) systems. Both single user-MIMO (SU-MIMO) CoMP and […]
