The Shannon capacity predicts the theoretical maximum rate of information transfer through a channel, at a given noise level. However, this concept has limited application in LTE networks. As such, alpha-Shannon capacity, which is modified from Shannon capacity, has been proposed for use in LTE networks. Nonetheless, the existing alpha-Shannon capacity(More)
Packet size and modulation scheme can play an important role on optimizing the data rate of Long Term Evolution (LTE) system. The performance of the existing LTE system is evaluated in this paper in term of throughput and packet loss for Orthogonal Frequency-Division Multiple Access (OFDMA) modulation scheme with different packet sizes. The performance of(More)
Peer-to-peer (P2P) systems have been widely used in today's network. The limitation of server-client systems in number of clients that can be served leads to invent p2p systems enable sharing of contents with individual nodes in the network. In p2p systems tasks such as video streaming are shared among individual nodes directly to other nodes in the(More)
Modulation and Coding Schemes (MCSs) is one of the parameters that can be adapted according to the channel condition. The IEEE 802.16 system specifies several MCSs, such as QPSK, 16-QAM, 64-QAM in case of modulation and 1/2, 2/3, 3/4, 5/6 in case of coding. However, the specification does not provide a policy to select MCS for various link conditions. In(More)
