The effect of multiple sink on the lifetime of WSN for different grid geometry

A wireless sensor network is a collection of sensor nodes also known as motes. Nodes on-board batteries are very small. Sensor nodes are used in many applications such as for home security applications, health monitoring, and surveillance and industrial applications. Sensors nodes are spatially distributed either randomly or in a systematic manner around the targets to perform operations. The range defined in the network allow nodes to sense and collect the data about the targets and perform many preprocess that collect data before sending to a sink node. In order to send data from source to destination nodes are used but the size of nodes are limited so energy saved in tem too is limited which acts as constraints to them as it bound them in the limit of processing capability with low battery power. Wireless sensor network basically perform operation of sensing or monitoring data from the sensor nodes by collecting data in the given or desired network. Information from various nodes are collected and passed to the decided destination. Data aggregation is performed to collect the data from the nodes present the network and transmit it. With the help of data aggregation we can reduce the energy consumption by eliminating the redundant data, the implosion and overlap of data among the nodes in the network. For era of development in the field of the improvement in the energy of wireless sensor networks (WSN) multiple sink with grids geometry is an excellent technique. This paper we will analyze the effect of multiple sink on the life time of the nodes.
