Telecommunication 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 moreLoad balancing is one of the key target of LTE Self-Optimization Network (SON). In this paper, we propose a load balancing method for LTE downlink network, namely Load Vector Minimization based Load Balancing (LVMLB) method. Load Vector (LV) is a vector whose elements are the load values of cells and sorted in descending order. The order of LVs is […]
Read moreFuture wireless networks will face the dual challenge of supporting large traffic volumes while providing reliable service for delay-sensitive traffic. To meet the challenge, relay network has been introduced as a new network architecture for the fourth generation (4G) LTE-Advanced (LTE-A) networks. In this paper, we investigate resource allocation including subcarrier and power allocation for LTE-A relay […]
Read moreMobile data traffic is expected to increase 11-fold between 2013 and 2018. A more dynamic and flexible network is needed to cope with the growing data volume. Software defined networking (SDN) enabled by, for example, the OpenFlow protocol is a potential solution to improve the flexibility and agility of the mobile data network by decoupling […]
Read moreIn this paper, we investigate the impact of jamming threats on the performance of LTE networks. First, we develop a three dimensional theoretical space to explore various jamming attacks. Next, we construct a set of attack scenarios by utilizing the dimensions of this space. To observe the impact onLTE network performance, we use ns-3 to implement the scenarios […]
Read moreThe use of wirelessly internetworked miniaturized biomedical devices is promising a significant leap forward in medical treatment of many pervasive diseases. Recognizing the limitations of traditional radio-frequency wireless communications in interconnecting devices within the human body, in this paper, we propose for the first time to develop network protocols for implantable devices based on ultrasonic transmissions. We start off by […]
Read moreHexagonal focused arrays operating at 433MHz for microwave hyperthermia have been designed for the first time by optimizing the power transmission efficiency of the system consisting of the transmitting hexagonal array, a testing (receiving) antenna introduced in the target area, with an equivalent phantom representative of human body in between. The excitations of the arrays are obtained by […]
Read moreFingerprinting based localization is one of the most widely used indoor localization methods. This method is divided into two phases: during the off-line training phase, fingerprints within the area of interest are collected and stored in a fingerprint database; during the on-line mapping phase, the real-time location of a device is estimated by mapping itself to the […]
Read moreWith the help of digital resources, self-description of smart objects causes some limitation into the input qualities because of the long established physical appearances. Also to realize the capability of objects to understand and recognize the data. If an uninstrumented surface is provided, the object should be able to sense gestures and touches upon the […]
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 […]
