Abstract |
Wireless sensor networks are a group of small sensor nodes that can monitor and sense the surrounding area and transmit data to a main station. The serious challenge for sensor networks is the restrictions on energy in the nodes, which sometimes affects the networks survival. As a result one major issue to consider in designing these networks is the development of protocols and algorithms that make the best use of limited sources, especially energy sources. One very important algorithm is the routing algorithm which is directly connected to the energy consumption and network lifespan. Among the routings offered for these networks, hierarchical routing protocols turn out to save a great deal of energy. In these protocols, the present nodes with higher energy can be used to gather data and routing information. In this paper, a clustering approach is proposed based on a three-way method to increase the network lifespan. The efficiency and performance of the proposed algorithm has been tested using simulation tools in different scenarios. Final results show an overall improvement in the network performance including network lifespan and some more basic criteria in compare to other algorithms. |
