“…A complex real battery is represented by a simpler equivalent battery, and a high-level analytical expression is derived on the basis of lowlevel analysis. One previous modeling attempt in this direction was reported in [13]. In this paper, we provide a new model which is substantially improved in terms of computational complexity, accuracy and usefulness.…”

Predicting the time of full discharge of a finite-capacity energy source, such as a battery, is important for the design of portable electronic systems and applications. In this paper we present a novel analytical model of a battery that not only can be used to predict battery lifetime, but also can serve as a cost function for optimization of the energy usage in battery-powered systems. The model is physically justified, and involves only two parameters, which are easily estimated. The paper includes the results of extensive experimental evaluation of the model with respect to numerical simulations of the electrochemical cell, as well as measurements taken on a real battery. The model was tested using constant, interrupted, periodic and non-periodic discharge profiles, which were derived from standard applications run on a pocket computer.

“…Each node N i computes its own state of charge (SOC) which is given by Q/Q max where Q is the remaining battery capacity and Q max is the initial battery capacity. The remaining battery capacity can be computed by the Rakhmatov battery model [19]. Initially N i initializes its SOC min and SOC max to SOC.…”

Abstract-In this paper we present a Table less Position based Routing (TPR) scheme for low power data centric wireless sensor networks. TPR is localized, uses greedy forwarding approach, and does not rely on neighborhood information. These characteristics reduce the communication overhead (no neighborhood information exchange), make the protocol highly scalable (no routing tables are maintained and beacons are not exchanged when a node leaves or enters the networks), and it performs better in mobile environments (as the next hop is non-deterministic and is computed at real time). It also deals with dead end problems by a recovery strategy in a distributed and localized way. TPR is implemented in the OMNET++ based discrete event simulation environment PAWiS (simulation framework for low power wireless sensor networks). The results show that TPR provides guaranteed delivery, extended network life time, and a mechanism to route on the basis of end to end delay and/or energy consumption.
