Heteroleach Protocol for Improvement of Stable Operation of Wireless Sensor Networks
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2016, Vol 18, Issue 2
Abstract
Abstract : Wireless sensor networks(WSN) are very much sensitive to energy consumption by the sensor nodes. Many protocols have been designed for efficient use of energy of the nodes so that the lifetime of the network can prolong. The sensors consume more energy in communication of sensed information to the base station as compared to actually sensing the physical phenomena and processing it. Therefore selection of proper routing protocol for communication is crucial in sensor networks. Hierarchical and clusteredapproaches are proven to be more efficient as compared to flat based organization of WSN. LEACH and other variants of dynamic clustering approaches perform well in case of homogeneous network but a lot of overhead energy is used for balanced operation of the network. We propose a smart heterogeneous method in which we do not need to run a setup round after each steady state round. Both the phases need near about same amount of energy. So if we reduce the number of setup operations which causes overhead energy loss, we can perform more steady state operations with the same energy nodes. To achieve this we use heterogeneous nodes. Some ofthe nodes have higher energy as compared to normal nodes which can serve as cluster heads for longer time without a need of setup operation repeatedly and save energy. A proper selection of a multiplying factor α for energy of high energy, high priority nodes, can prolong the lifetime up to twice as compared to LEACH.
