An energy-efficient model using cooperative MIMO in wireless sensor network

Abstract

Data integrity and conservation of energy is one of the important issues in today’s wireless network world. In wireless sensor network, the sensors are formed into different clusters and cooperatively communicate with other clusters. A cooperative cluster-based energy-efficient model is proposed to save the energy. In this model, every cluster has a cluster head that will monitor all the sensors in a cluster. The formation of cluster reduces the energy consumption compared to non-clustered WSN. In proposed model, a big MIMO antenna is way to communicate between the clusters. This big MIMO is formed by two boundary nodes of two different clusters and acts as a cooperative MIMO antenna and transfers data to cluster to reach the sink or destination making the network more reliable.
