Trellis Coded Modulation (TCM) combines convolutional encoding with PSK or QAM signaling to provide spectrally efficient communication with forward error correction. Although the Ungerboeckpsilas TCM (Trellis Coded Modulation) [1,2] is attractive in terms of high efficiency with low descending data rate by coding and high coding gain, it is difficult to(More)
Energy is an igniting issue in the domain of wireless sensor networks. To overcome this issue, the technique of data aggregation is introduced. As the aggregator node collects data from many sensors so it becomes very interesting for compromisers. Unfortunately these aggregator nodes could be under the influence of various attacks. Under such circumstances,(More)
