New Cache System-Based Power-Aware Algorithm in MANET

The increasing use of mobile devices in wireless environments led to many studies about power-aware algorithms and protocols to improve the lifetime of device’s battery. This paper studies the implementation and testing of a new power-aware algorithm, PSWA, associated with a Cache System, and tested with the WRP routing protocol, in a Mobile Ad hoc Network scenario. A scheme that does not use the sleep schedule for the nodes it was used, nodes automatically fall asleep if they do not deal with data and routes. In the simulation scenario the WRP was chosen because it has a better performance in real-time traffic, and this type of traffic is commonly used today. The simulation results show an important decrease in energy consumption close to 10% with the association of the new power-aware algorithm.
