Abstract:

Based on the maximum independent set and first-fit algorithm, we design a data aggregation algorithm, Peony-tree-based Data Aggregation (PDA). On the basis of the PDA, using the time-division multiplexing method, we introduce the concept of low-power sleep schedule in the cyclical time slot of data aggregation. It is largely possible to reduce the amount of data transmission,network time delay and achieve low-power data aggregation. Simulation results show that the proposed algorithm can reduce network energy consumption, prolong the network lifetime and reduce the network delay cost.

Key words: wireless sensor network, data aggregation, sleep scheduling, delay cost
