Abstract

Wireless sensor networks are an enabling technology for many future surveillance-oriented applications. Before a practical wireless sensor network is realized, however, significant challenges must be overcome. Chief among the obstacles to netted sensors is providing low power, robust communications between sensor nodes. Multiple Inputs, Multiple Output (MIMO) communication promises performance enhancements over conventional Single Input and Single Output (SISO)technology for the same radiated power MIMO is the use of multiple antennas at both the transmitter and receiver to improve communication performance. Wireless networking is now commonly associated with MIMO because it offers significant increases in data throughput and link range without additional bandwidth or transmit power. Spatial multiplexing is a transmission technique in MIMO wireless communication to transmit independent and separately encoded data signals from each of the multiple transmits antennas. Therefore, the space dimension is reused, or multiplexed, more than one time. The wireless networking is modeled by simulation run by Matlab software. This project aims to study the performance of this technique on certain parameter and compared to other transmission technique in wireless network for example SISO technique. The parameters to be examined are delay, bit error rate (BER) and energy consumption.
