A power-aware reliable routing Algorithm for wireless sensor networks

Wireless sensor networks are very much concerned on conserving power and error control coding is a considerable burden on this power conservation. Thus, this paper proposes a diversity based routing algorithm to achieve the reliability in the absence of error control coding. Two diversity combining techniques are also proposed. The simulation results demonstrate that the proposed routing algorithm achieves the reliability that of many simple linear block codes while outperforming some. Moreover, the low complexity due to the absence of error control circuitry, reduces power consumption greatly.
