  • Flowchart for Clustered-Based Channel Allocation Management Scheme

    In the GSM system, several Base Transceiver Station (BTS) are controlled by a single Base Station Controller (BSC). In this paper, the BTSs in a given BSC is referred to as a cluster.  In this paper, flowchart for clustered-based channel allocation management scheme is presented. The mechanism is meant to reduce call blocking/dropping to the barest minimum. Usually, traffic intensity value varies from one BTS to another, as it is directly proportional to the number of GSM users that make or r...

    Performance Evaluation of Link Quality Indicator of a Wireless Sensor Network in an Outdoor Environment

    Wireless Sensor Network (WSN) has in recent times solved the problems associated with remote sensing and monitoring. However, link quality had been the major key player in the sensing and transmission of sensed signals to remote places especially in WSN. In this work, the effects of link quality indicators in an outdoor monitoring environment were investigated. The investigation carried out helps in evaluating the performance of these indicators to the monitoring capability of WSN in linear t...

    SIGNAL TO NOISE RATIO ESTIMATION OF QAM AND QPSK MODULATION TECHNIQUE AT 910MHz AND 2116.4 MHz USING MEASURED DATA

    Estimation of signal to noise ratio for the received signal is an important task in communication systems. The knowledge of the SNR is a requirement on many systems in order to perform efficient signal detection and link adaptation. In adaptive modulation system we need a way to decide which modulation level is best suited for the present channel condition, in this paper we decided to use the estimated SNR of the link as a channel metric to decide the switching levels. The channel estimation ...

    Flowchart for Call Management Scheme through Users Mobility Control

    The tremendous popularity of wireless technologies during the last decade has created a considerable expansion of wireless networks both in size and use. These facts, together with a great variety of mobile devices and numerous different services that are becoming increasingly resource-demanding, have attracted the attention of many researchers into the area of radio resource planning and optimization. In wireless cellular networks, it is important to develop model or schemes to facilitate ef...
