Abstract:

Using virtual multiple-input single output (MISO) technologies, the performance for cooperative transmission in clustered wireless sensor networks
(WSNs) is studied. The symbol-error-rate (SER) formulas are derived for the phases of intra-cluster broadcasting and inter-cluster cooperative transmission as well as for end-to-end, respectively. Moreover, an effective low bound on the end-to-end SER is proposed. Besides, an optimal power allocation model using the end-to-end SER as constraints is proposed. An efficient method for solving the optimal solution of the model is proposed. Simulation shows that the model has energy-saving advantages under different SER requirements.

Key words: wireless sensor network, cooperative transmission, virtual multiple input single output, symbol-error-rate
