“…Recently CMIMO technique and its variations like CMISO, are adopted by ad-hoc networks in wireless sensor network for the improvement in energy efficiency over SISO systems by exploiting the spatial diversity enhanced from cooperative communication [14]- [15]. These ad-hoc networks are also of great use in requirements of major applications.…”

This paper considers the wireless sensor networks and highlights its applications in present time and mainly focuses on the two main techniques for saving maximum energy in transmitting information in WSN and these are multi-input multi-output (MIMO) and cooperative MIMO (CMIMO). Under this paper there is a comparison of energy efficiency in MIMO and single-input single-output (SISO) system for both transmission energy and circuit energy. Then there will be the discussion of CMIMO advantages, its energy model, properties, comparison with the equivalent technique (DCA) and the most important strategy used under CMIMO system is node sleep strategy and its significance in front of non-node sleep strategy will be discuss in this paper.

“…The Alamouti -STBC is known as one of the most effective diversity methods in MIMO system used to combat the effect of channel fading in wireless communication. In [7], Alamouti code based on MIMO system and modulation has been introduced to minimize power consumption under constraint throughput for sensor networks. But they did not investigate the enhancement of BER performance.…”

“…The usage of dual antennas in a single IEEE 802.15.4 device has already been common and commercialized such as in [4], [5], and [6]. In [7], they introduced a study of energy efficiency of MIMO techniques in WSN based on its power consumption and they assumed Alamouti diversity codes are used for the MIMO and cooperative MIMO system. It shows that the power consumption of MIMO system-based WSN devices can be more efficient compare to SISO system -based WSN devices in certain distance transmission.…”
