....at various levels of the communication stack. Aside from minimizing power consumption at the hardware level [24] MAC layer protocols developed for energy savings mostly take advantage of overhearing and scheduling to allow nodes to sleep while they are not transmitting or receiving messages [8][12] 27] At the network and routing layer, schemes work to minimize power along the transmission path [26] set routes according to the energy remaining at nodes along that path [3t] and use mechanisms to save power through the distribution of messages among various paths from source to ....

....stack. From the bottom to the top, special hardware [18] is designed with multiple energy dissipation settings. MAC layer protocols developed for energy savings mostly take advantage of overhearing and scheduling to allow nodes to sleep while they are not transmitting or receiving messages [7][11] At the network and routing layer, solutions are diversified. Data placement schemes [4] minimize energy along the transmission path through data caching. In [19] R. Ramanathan et al. adjust communication range dynamically based on the node density to conserve energy consumed in ....

....energy gains are, however, only achieved in very dense networks. We will discuss this 3 issue further on in this paper, when we integrate STEM with GAF. An approach that is closely related to STEM is the use of a separate paging channel to wake up nodes that have turned off their main radio [10]. However, the paging channel radio cannot be put in the sleep mode for obvious reasons. This approach thus critically assumes that the paging radio is much lower power than the one used for regular data communications. It is yet unclear if such radio can be designed. STEM basically emulates the ....

....their benefits with those of STEM to achieve compounded energy savings. STEM is essentially a technique to quickly transition to the transfer state, while making the monitoring state as energy efficient as possible. Other authors have proposed to do this wake up using a separate paging channel [10]. This approach critically assumes that the listen mode of this paging radio is ultra low power. However, the difference in the transmission range between the data and wakeup radio presents a major difficulty. STEM offers an alternative by trading energy for latency. Furthermore, if such a ....
....the solution is to completely separate data transfer from wakeup. A natural choice is to use two radios operating in separate frequency bands. As shown in Fig. 3, the radio in band ft is only turned on in the transfer state, and the wakeup band f2 can be viewed as a separate paging channel. Unlike [10], we are not limited by the availability of an ultra low power radio for this paging channel. Instead, we can use the most efficient radio available and further reduce the energy consumption by putting it in our lowpower listen mode. This allows us to trade energy savings versus latency, beyond ....

....position apriori (configured during network setup) Nodes can determine their position using signal strength measurements to nodes with already known position, or they infer it from the hopcount distance their immediate neighbors have to the anchor nodes. A local address assignment protocol [6] determines locally unique node addresses. Locally unique means that no node has two neighbors with the same address x, but x can be re used in more distant parts of the network. URL: bwrc.eecs.berkeley.edu Research Pico Radio Default.htm. In fact, in sensor networks globally unique node ....
