%0 Journal Article %T Combining Harmony Search and Learning Automata for Topology Control in Wireless Sensor Networks %A Mohamad Nikravan %A Seyed Mahdi Jameii %J International Journal of Wireless & Mobile Networks %D 2013 %I Academy & Industry Research Collaboration Center (AIRCC) %X One of the critical challenges in wireless sensor networks (WSNs) is energy conservation. Topology control is a vital process to minimize energy consumption and maximize the network lifetime. In this paper, we propose a distributed topology protocol with transmission power adjustment based on harmony search and learning automata algorithms called HSLATC (Harmony Search and Learning Automata based Topology Control protocol). In HSLATC, proper transition radius of the sensor nodes can be determined. Because of the intelligent determining the transition radiuses of the nodes in the proposed protocol, it is able to provide the full connectivity in sparse deployment and decreases the energy consumption of the sensor network and prolongs the network lifetime. The simulation results show high efficiency of the proposed protocol. %K Wireless Sensor Network %K Topology Control %K Network Lifetime %K Harmony Search %K Learning Automata. %U http://airccse.org/journal/jwmn/1212wmn07.pdf
