Improving a new time-independent transmission technique using hybrid multiplexing methods in wireless sensor networks

In communication systems, multiplexing techniques are used in order to provide services to a large number of users and reduce communication costs. How users will use these multiplexed communication paths is determined by the Medium Access Control (MAC) protocols. When the wireless communication systems are examined in terms of multiplexing techniques, it is seen that multiplexing is done in frequency and time domain in general. Multiplexing is done on the frequency plane to create frequency channels that can be used by different users. When number of users is more than the frequency channels, it is possible to provide the frequency channels to different users in different time periods by multiplexing on the time plane. Delay is inevitable when multiplexing is performed on the time plane. In this work, a new technique has been developed that multiplexing in the phase plane for wireless sensor network applications where delay is important. The number of communication channels has been increased with this new technique, which multiplexing in phase plane as well as general multiplexing techniques. Simulation studies of the developed technique have been made and the results obtained are shared. This time-independent multi-channel structure offers parallel communication for applications where data size is low and latency is important.
