A Novel Optimal Routing Algorithm by Creating Concentrically Sectors in Wireless Sensor Networks

Sensor networks are composed of many sensorsusually far from the region is available. Routing method inwireless sensor networks to transfer information from sensornodes to base station is especially important. Optimumconsumption of energy is important requirements in wirelesssensor networks because sensor systems typically use batterypower. In this paper, we have presented a routing algorithm todetermine the optimal path of energy consumption viewpointto transfer information from sensor nodes to base station withthe data transmission by multi skip. In this algorithm,performance region is divided to some sectors and there areseveral relay nodes in the each sector. Relay nodes gather datafrom sensor nodes around them and data transfer to the basestation based on the shortest path and minimum skip possiblein two-dimensional coordinates (x, y) to the base station. Atthe end, we have compared the presented algorithm withEESR (Energy Efficient Sensor Routing) algorithm.Simulation results show the optimal performance of presentedalgorithm in energy consumption, delay and number of livenodes.
