Connecting a mobile ad hoc network and wireless sensor network is the focus of our investigation. In order to remotely access a sensor node from a mobile node, first, a node in the MANET needs to be connected to a sensor network coordinator. The chal

The low-density parity-check code is known for a superior signal reception capability in AWGN and/or flat fading channels with respect to increased encoding rates, however, its performance degrades when the communication channel becomes multipath fad

In a mobile communication channel, the multi-user interference is one of the major performance degradation factors, and restoring the signal-to-signal orthogonality among users is the challenging problem. As a solution to the problem, we proposed a m
