In this study, we introduce novel power saving schemes for multihop wireless networks. The proposed schemes achieve high energy efficiency and good network throughput without using any global clock synchronization scheme. The main idea of the proposed power saving schemes is to dynamically adjust the length of the beacon interval based on the communication demand. Due to this dynamic adjustment of the beacon period, mobile nodes can sleep longer if they are not involved in any active communication and achieve both high energy-efficiency and high network throughput. We conduct a comprehensive simulation study to evaluate the efficiency of the proposed protocols in terms of energy consumption, network throughput, latency and packet loss ratio. The results of our simulation study show that the proposed dynamic beacon interval adjustment approach performs very well and energy efficient. Especially, the result of one of the proposed protocol is really promising. This scheme conserve about 40% of battery power without compromising throughput compared to IEEE 802.11 Power Saving Scheme. |
