Real Time Scheduling for Wireless Sensor Networks
نویسندگان
چکیده
In this paper we propose a new scheduling algorithm called Real Time Scheduling (RTS). This algorithm deals with all the contributing components of the end-to-end travelling delay of data packets in sensor network to achieve better power management and stable routes in case of failure. RTS delays packets at intermediate hops (not just prioritizes them) for a duration that is a function of their deadline. Delaying packets allows the network to avoid hot spotting while maintaining deadline-faithfulness. We compare RTS with another prioritizing and scheduling algorithm for real-time data dissemination in sensor networks. This paper simulates RTS based on two typical routing protocols, shortest path routing and greedy forwarding with J-Sim.

Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...
