Energy Efficient Routing in Random Deployment of Wireless Sensor Networks
نویسنده
چکیده
ireless sensor networks are composed of large number of tiny sensor nodes that are used to observe, monitor and collect data about a certain phenomenon of interest. Wireless sensor networks are often deployed randomly due to the harsh environments and their hard to reach locations. The sensor nodes used in wireless sensor networks are energy constrained. Energy efficiency is thus the main concern of the network. Energy efficiency depends upon the routing mechanism that is used to forward packets from the sensor nodes to the base station. Cluster based hierarchical routing protocol; LEACH is most conventionally used for energy efficient routing in wireless sensor networks. LEACH protocol has undergone many enhancements and improvements over the years to improve the energy efficiency of the network. In this paper we address the key issue of energy efficient routing where the sensor nodes are deployed randomly. We propose to enhance LEACH protocol to reduce the energy consumption and also verify and validate the enhancement by using MATLAB. Keywords—Energy Efficiency, Hierarchical Routing, LEACH, Node deployment, Wireless Sensor Networks.
