An Enhanced Packet Gathering and Secure Multicast Routing Scheme in Wireless Sensor Networks

Wireless Sensor Networks consists of group of self organizing, light weight sensor nodes that are used to cooperatively monitor physical or environmental conditions. Each Sensor node in a WSN is equipped with sensing, computing and communication elements. The Wireless Sensor Networks detects and estimate event features from the collective information provided by sensor nodes. In sensor network, sink node is available in cluster network. It has to control the communication process from cluster Member node to Cluster Head node. The sink node will get updated by its location in the network. The Proposed packet gathering and multicast routing Scheme is used to improve the packet gathering approach for each cluster head in wireless sensor network. The node coverage level is monitored and the packet gathering assessment level is obtained. The proposed scheme achieves better performance in terms of efficient routing, googd throughput, network life time and low delay network performance metrics than previous schemes based on simulation results.
