RÉSUMÉ

Wireless Sensor Networks consist of sensor nodes with sensing and communication capabilities. We focus on data-aggregation techniques in energy-constrained sensor networks. The main objective of data-aggregation algorithms is to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. To enhance the lifetime of wireless sensor networks, an energy efficient transmission technique is required so that energy consumption must be minimized while satisfying given throughput and delay requirements. In this context, we proposed an energy model for wireless sensor networks based on cooperative (MIMO) multiple-input multiple-output based communication , taking into consideration both the transmission energy and data aggregation energy. We also show that over some distance ranges, cooperative MIMO transmission approach outperforms SISO approach. Simulation outcome shows that jointly considering both cooperative MIMO communication and data aggregation method will further reduce the total energy consumption. Simulation results are included.
