| Abstract: | Transmission successful probability of the random power control approach for clustered wireless sensor networks is analized in this paper.The minimum and the maximum of transmission power during the intra-cluster communication can be choiced to meet the transmission successful probability requirement of networks.The simulation results show that random power control can improve the energy efficiency compared to the conventional fixed power control in clustered wireless sensor networks where sensor nodes are distributed densely. |
| Keywords: | wireless sensor network(WSN) clustering power control transmission successful probability |
