Abstract: Wireless sensor networks are composed of many wireless sensing devices called sensor nodes. These nodes are small in size, limited in resources and randomly deployed in harsh environment. The replacement or recharging of battery is difficult; therefore energy consumption is necessary for WSN. Employing Multi Input Single Output (MISO) links can improve energy efficiency in Wireless Sensor Networks (WSN). Although a sensor node is likely to be equipped with only one antenna, it is possible to group several sensors to form a virtual MISO link. Such grouping can be formed by means of clustering. Cooperative MISO is considered here which aims at reducing energy consumption in multi hop WSNs. In order to improve the energy efficiency a sleep technique is also considered
