An ad-hoc wireless sensor network organizes itself as a network that many sensor nodes automatically communicate each other in a certain area. Each sensor node consists of a transmitting unit, receiving unit, central processing unit, and battery unit. Because of the sensor node's battery unit that may not be reachable or rechargeable, it is important for both the base station and sensor nodes communicating very well for less energy consumption of sensor nodes to extend the entire ad-hoc wireless sensor network lifetime. Moreover, in this paper, the ad-hoc wireless sensor network is divided into many clusters and every cluster contains only one cluster head. All wireless sensor nodes will transmit their messages to the cluster head where they belong to. Then, the cluster head will return a confirmed message back to every sensor. However, it dissipates much energy to retransmit a confirmed message from the cluster head to the sensor node. Since the base station is far away from the sensed area, it is necessary to have a forwarding station forwarding the message from the sensed area to the base station. Finally, this paper proposes the forwarding station integrated the non-confirmed routing protocol so that the network lifetime can be extended very well. Also, simulation results show the network lifetime extended well and the performance is much better.
