An Efficient Aggregation and Routing Algorithm Using Multi-hop Clustering in Sensor Networks

Sensor networks consist of sensor nodes with small-size, low-cost, lowpower, and multi-functions to sense, to process and to communicate. Minimizing power consumption of sensors is an important issue in sensor networks due to limited power in sensors. Clustering is an efficient way to reduce data flow in sensor networks and to maintain less routing information. In this paper, we propose a multi-hop clustering mechanism using global and local ID to reduce transmission power consumption and an efficient routing method to improve performance of data fusion and transmission. Simulation results show that our algorithm can increase life time and disperse power consumption among the nodes.
