Energy efficient protocols are important in ad-hoc networks since battery life for wireless devices is limited. The IEEE 802.11 protocol specifies a simple power save mechanism (PSM) to conserve energy. Packets are advertised for a fixed length of time, known as an advertisement window, at epochs known as beacon intervals. However, the protocol needlessly wastes energy when traffic is relatively light in a network. This paper summarizes new techniques and schemes that are not based on the IEEE 802.11 standard. It also includes the classification of MAC protocols used in ad-hoc networks.

An Improved Power Saving Mechanism for MAC Protocol in Ad Hoc Networks

July 2005

Ad hoc networks have recently become a hot topic. In ad hoc networks, battery power is an important resource, since most terminals are battery powered. Terminals consume extra energy when their network interfaces are in the idle state or when they overhear packets not destined for them. They should, therefore, switch off their radio when they do not have to send or receive packets. IEEE802.11 ... [Show full abstract] features a power saving mechanism (PSM) in Distributed Coordination Function(DCF). In PSM for DCF, nodes must stay awake for a fixed time, called ATIM window (Ad-Hoc Traffic Indication Map window). If nodes do not have data to send or receive, they enter the doze state except for during ATIM window. However, ad hoc networks with PSM have larger end-to-end delays to deliver packets and suffer lower throughput than the standard IEEE802.11. To solve this problem, this paper proposes a protocol that reduces delay and achieves high throughput and energy efficiency. Simulation results show that our proposal outperforms other PSMs in terms of throughput, end-to-end delay and energy efficiency.

Designing Power efficient system for Ad-Hoc network using SIMPA

December 2008

An Ad-hoc network is a collection of cooperative wireless nodes working together to form a network. Nodes in an ad-hoc network can work in an autonomous manner and act as routers forward network traffic. Power conservation is critical in an ad-hoc network, a wireless nodes may be portable battery operated devices with limited transmission capabilities and poser saving strategies can increase the ... [Show full abstract] longevity of a network. On critical issue for almost all kinds of portable devices supported by batter powers is power saving. Without power, any mobile device will become useless. Battery power is a limited resource, and it is expected that battery technology is not likely to progress as fast as computing and communication technologies do. Hence, how to lengthen the lifetime of batteries is an important issue, especially for MANET. IEEE 892.11 power-save mode (PSM) has been proposed in wireless LANs and multi-hop wireless networks to coordinate power states of wireless devices. In IEEE 802.11 PSM, power management decisions to wake up wireless devices or put them to sleep states are made periodically in every beacon interval. In this paper, we demonstrate via a rigorous, analytical model that such a periodic structure together with its signaling overhead leads to both energy and bandwidth under-utilization. We then devise SIMPA, a new power management protocol based on IEEE 802.11 PSM, to decouple the power management decision points and the beacon intervals, so as to allow fine grained control. In SIMPA, wireless devices can switch to the sleep state inside a beacon interval or extend their active states beyond one beacon interval.

Designing Power efficient system for Ad-Hoc network using TC-PSM

January 2009

Turning the devices to low-power states when they are not in use is an important technique to conserve energy for battery-powered wireless devices. The IEEE 802.11 power saving mode is one of the most popular techniques in wireless LAN and multi-hop wireless networks to coordinate the power states of communication devices. Providing energy efficiency in MAC (Medium Access Control) layer, while ... [Show full abstract] achieving desirable throughput, is an important research issue in the area of wireless networking. A wireless LAN such as IEEE 602.11 using the Distributed Coordination Function (DCF) also provides a mechanism for power conservation which allows each node to “sleep” for some amount of periods, but also requires the nodes to wake up periodically and stay “awake” for a certain duration called the ATIM Window. We propose an enhancement called the Traffic Control Power Saving Mode (TC-PSM) to solve this problem by allowing nodes to enter the doze state when they are no more involved in data delivery even if they have already sent a beacon, an ATIM or an ATIM-ACK. Our objective is to reduce the energy consumption without any throttling to throughput.

Designing the Power Efficient System for Ad hoc Network using Cross Layer Protocol Design at the Lin...

September 2008

Designing energy efficient protocols for ad-hoc networks is important since there has been little improvement in the amount of energy stored on these devices. We demonstrate how this cross-layer technique can be used to augment both synchronous and out-of-band protocols. We then take advantage of carrier sensing to dynamically adjust the listening time for wake-up signal detection. We explore ... [Show full abstract] cross-layer design with interaction between the link layer and routing layer. We consider using multiple levels of power save protocols at the link layer. Each level presents a different tradeoff in terms of energy and latency (i.e. levels with an increased energy consumption have a lower latency). We explore a routing layer protocol design that discovers routes which allow the nodes to consume as little energy as possible while maintaining a user-specified latency. In this work, we explore protocols that use cross-layer designs for energy saving and some cross-layer tradeoffs that arise as a result of reducing energy power save protocols.

Improving power save protocols using carrier sensing and busy-tones for dynamic advertisement window

January 2005

Energy efficient protocols are important in ad hoc networks since battery life for wireless devices is limited. The IEEE 802.11 protocol specifies a simple power save mechanism (PSM) to conserve energy. However, the protocol needlessly wastes energy when traffic is light in a network, and signifi-cantly increases packet latency. In this paper, we consider three techniques to improve the 802.11 ... [Show full abstract] PSM protocol. The first technique, Carrier Sense ATIM, uses carrier sensing to drastically reduce the energy wasted listening to the channel in 802.11 PSM. The second technique, Dynamic ATIM, dynamically extends the listen-ing period in 802.11 PSM based on packet advertisements that are overheard. In this manner, we are able to advertise data packets just as effectively as 802.11 PSM while signifi-cantly reducing wasteful listening. The final technique, Per-Link Beacon Intervals, allows sender and receiver pairs to schedule their wake-up times independent from all the other nodes in the network based on past packet arrival times. Our results show that this technique is able to significantly reduce the average packet latency causing no or relatively little increase in energy. All of the protocols are extensively tested using the ns-2 simulator.
