An Efficient Multiple Mobile Data Collector Scheme For Clustering Wireless Sensor Network

The wireless sensor network is made up of collection dense sensor node where collection of data from the sensing fields becomes an issue. In the existing system a VELCT (Velocity Energy Efficient Link Aware Cluster Tree) is used to construct a DCT (Data collection Tree) to collect the data from the CH (Cluster Head) and then relay it to the BS (Base Station). But this system fails to balance the energy between the sensor nodes. In the proposed system the EMDC (Efficient Multiple Data Collector) is used to implement multiple mobile data collector to collect the data from the cluster head. The Mobile Data collector called CV (Collector Vehicle) is deployed in multiple numbers to collect the data from the cluster head and then relay it to the base station. This prevents the creation of energy hole in the network and balances the energy between the nodes. The simulation results have shown better results when compared with the existing system. INTRODUCTION A wireless sensor network consists of numerous autonomous sensor nodes that are spatially distributed to sense and monitor various changes of the environment surrounding us. Such devices are also capable to communicate in wireless sensor networks and that can also sense, monitor, transmit, receive or process numerous data like pressure, temperature, sound, motion, humidity etc. The WSN is built of nodes from a few to several hundreds or even thousands, where each node is connected to one or more sensors. Each such sensor network node has typically several parts: a radio transceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source, usually a battery or an embedded form of energy harvesting. A sensor node might vary in size from that of a shoebox down to the size of a grain of dust, although functioning motes of genuine microscopic dimensions have yet to be created.

Size and cost constraints on sensor nodes result in corresponding constrains on resources such as energy, memory, computational speed and communication bandwidth. The topology of the WSNs can vary from a simple star network to an advanced multi-hop wireless. The propagation technique between the hops of the network can be routing or flooding. Sensor nodes collect data from the surroundings and communicate the data with other sensor nodes. In flat wireless sensor networks, the data is directly passed from sensor nodes to base station. In cluster based wireless sensor networks, the sensor nodes transmit the data to a cluster head which then relays it to the base station. In a multiple mobile data collector scheme the data is collected by the cluster head and then sent to the CV which then relays it to the BS. RELATED WORKS In the literature survey various data collection scheme have been introduced. The LEACH(Low-Energy Adaptive Clustering Hierarchy)protocol [1] helps in the formation of the cluster and election of the cluster head. The sensor nodes collect the data from the sensing fields and then give it to the cluster head which gives the data to the BS. This system fails because of the energy hole creation. Since the cluster head near by the BS send the data first than the far nodes. Hence the cluster heads nearby drain of out energy. The CREEC (Chain Routing With Even Energy Consumption)[2] algorithm is used to create a chain of cluster where one cluster head collects the data from the sensor nodes and then send it to nearby cluster head where the data passes through a chain of cluster to reach the BS. This increases the delay in the network as the data have to traverse through a long chain of clusters.
