摘要: The paper examines the performance as well energy consumption Issues of a wireless sensor network providing periodic data from sensing field to remote receiver. sensors are assumed be randomly deployed. We distinguish between two types organizations, one with single layer identical (homogeneous) and an additional overlay fewer but more powerful (heterogeneous). formulate study their estimated lifetime based on clustering mechanism varying parameters related field, e.g., size, distance. quantify optimal number clusters our model show how allocate different layers.
