SPERT: A stateless protocol for energy-sensitive real-time routing for wireless sensor network

Putting constraints on performance of a system in the temporal domain, some times turns right into wrong and update into outdate. These are the scenarios where apposite value of time inveterate in the reality. But such timing precision not only requires tightly scheduled performance constraints but also requires optimal design and operation of all system components. Any malfunctioning at any relevant aspect may causes a serious disaster and even loss of human lives. Managing and interacting with such real-time system becomes much intricate when the resources are limited as in wireless sensor nodes. A wireless sensor node is typically comprises of sensing unit, processing unit and transmission unit. Intercommunication of these energy, memory and processing constraint devices form wireless sensor network. In this paper, SPERT: a mechanism of approaching the sink from multi-sources in the fast and ef?cient manner, is proposed. It simply relies on in-network processed information which appreciatory decreases too much beacons among neighboring nodes resulting in increasing the network lifetime. More-over, every node is aware of its time to get its message to destination. Thus delay in processing and decision making also decreases leading in favor to real-time communication.
