Energy-efficient data transmission is one of the key factors for energy-efficient wireless sensor networks (WSN). Cooperative multiple input multiple output (MIMO) explores the wireless communication schemes between multiple sensors emphasizing the MIMO structure. In this paper, an energy-efficient cooperative technique is proposed for a WSN where selected numbers of sensors at the transmitting end...
An energy efficient cooperative MIMO technique is proposed in the wireless sensor networks where fixed constellation size is considered in transmitting both the local and long haul communication. A selection criteria is used here based on the channel conditions where a selected numbers of sensors in a cluster are used to form a multiple input multiple output (MIMO) structure wirelessly connected with...
Energy efficient transmission with fairly high capacity is an attractive feature for energy constraint wireless sensor network. This opens a door for the outage analysis keeping the energy efficient performance active. We propose to employ LDPC codes to provide reliable communication while saving power in the sensor networks. We derive the ergodic and outage capacity for a cluster head to DGN transmission...
Energy efficient data transfer is the key factor for the design of energy efficient wireless sensor network (WSN). IEEE 1451.5 standard explores the wireless communication schemes between multiple sensors and a data gathering node (DGN) emphasizing the multiple input single output (MISO) structure. Sensors participating in this MISO can be chosen selectively for more energy efficient data transfer...
An energy efficient cooperative technique is proposed for the IEEE 1451 based wireless sensor networks. Selected numbers of wireless transducer interface modules (WTIMs) are used to form a multiple input single output (MISO) structure wirelessly connected with a network capable application processor (NCAP). Energy efficiency and delay of the proposed architecture are derived for different combination...
A boundary value of the velocity of data gathering node (DGN) and a critical value for training overhead beyond which the scheme will not be feasible for a multiple input multiple output (MIMO) based cooperative communication for energy-limited wireless sensor networks is proposed in this paper. The performance in terms of energy efficiency and delay for a combination of two transmitting and two receiving...
