Energy Efficient Wireless Sensor Network Using Cooperative Communication
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
A network like sensor networks have energy constrained devices. The energy consumed by the nodes need to be less which prevents the earlier death of the sensor nodes due to drained energy level. Several techniques, methods are proposed and used to reduce the energy consumed by the sensor nodes. Thus lifetime of the network, one of the recent and significant research area in sensor network plays a vital role when deploying a sensor networks in real time applications having harsh environments where there is the chance for battery replacement is difficult or impossible. This work focuses on improving the lifetime of the sensor network using cooperative multi-input multi-output (CMIMO) transmission strategy. The nodes in the network cooperate with each other and then perform the transmission of data from source to the base station. So that the energy consumed by the nodes also reduced. Furthermore the cuckoo search optimization algorithm is used for cluster formation so as to make the clustering to be more energy efficient.
