A NEW ENHANCED ENERGY EFFICIENT MULTIPATH ROUTING APPROACH FOR WIRELESS SENSOR NETWORKS

Abstract

Wireless Sensor Network (WSN) is a group of Sensor Nodes (SNs) that work in the uncontrolled areas,
organized into a cooperative network. Wireless Sensor Networks are generally composed of a large number of
distributed sensor nodes that organize themselves into a multi-hop wireless network. Some of the major issues
in wireless sensor networks are energy consumption, lack of authentication data integrity and instability of path
link between sensor nodes which reduces the popularity of the sensor network. In recent years, the existing
methods have focused on attaining either energy consumption or security. The research work consists of
optimized multipath routing, residual energy based routing approach to make the wireless sensor networks
more secure with minimum energy consumption. The multipath routing is constructed to achieve high
throughput and load balancing. The optimal energy path is established to maintain the data packet flow in the
wireless sensor network unobstructed and the energy consumption model is developed to produce the minimum
energy consumption.. Residual Energy based Multipath Routing Approach is proposed which attains the
integrity and minimum residual energy. It uses load balancing to prevent congestion problems in the network
and the path stability is established based on link cost, link quality and bandwidth of the link.
