| Popis: | 99 In recent years, wireless sensor networks are extensively employed in the environment monitoring. It provides intensive environment monitoring in temporal and spatial respects, while the traditional environment monitoring can not afford it. Due to the limited energy in sensor nodes, it is of researching goal that the life time of sensor networks is prolonged by transmitting the sensed data to the base station in energy-saving way. We propose a new clustering algorithm which has cluster-heads be distributed evenly in temporal and spatial respects by two-phase cluster-head selection mechanism. With the restriction of the first-phase and the second-phase exclude distances, in each round, cluster-head can be distributed evenly in spatial respect. By classifying all the sensor nodes into four classes, all sensor nodes can become cluster-heads evenly in temporal respect. Furthermore, the number of transmissions of sensed data from cluster heads to the base station in each round is fixed to five, resulting in consuming almost the same energy for each cluster-heads in the steady state. Thus, our algorithm can save the energy significantly. |
