Abstract
Putting constraint on temporal domain based system performance, sometimes turns right into wrong, update into outdate, current into past and lawful into illegal. Therefore perfection satisfaction not only at hardware level but also at software level design is indispensable to quench the thirst of such ideal real time communication. From software perspective, in the timeless sensitive communication context, RTOS's kernel design must be sensitive enough to compensate different delays. Active contribution from each communication layer protocol as well as cross layer protocol makes the overall performance healthier and valiant. This active contribution becomes much important when the resources are in stringent constraint as in Wireless Sensor Network (WSN). A WSN is a network of energy, memory and processing constraint nodes. In this paper, we have proposed a protocol: REAR, to achieve the real-time routing with energy awareness feature in the ad hoc micro sensors network. It follows the customized proactive routing with in-network processing and localized behavior. Simulation results have intuited that REAR presents a better solution in energy consumption with the effect of improving the network life as well as increasing the performance efficiency in end-to-end delay.
