MIMO Technology for Wireless Sensor Network

Wireless sensor network, where an Access Point (AP) communicates with many Sensor Nodes (SN), which are simple, cheap, low-complexity and low-power communication nodes. Various schemes that employ multiple antennas at the transmitter and receiver are being considered to improve the range and performance of communication systems. By far the most promising multiple antenna technology today happens to be the so called Multiple-Input Multiple-Output (MIMO) system. MIMO algorithms in a radio communication send information out over two or more antennas. The radio signals reflect off objects, creating multiple paths that in conventional radios cause interference and fading.
