Poster Abstract: Enhanced Real-Time Transmission Using Time Gain in Wireless Sensor Networks

Abstract

Real-time applications in wireless sensor networks require that packets should reach to a sink within the time deadline. To satisfy the requirements, existing studies exploit nodes whose speed is higher than the desired delivery speed decided by the spatiotemporal approach. However, they fail real-time transmission in the area where there is no neighbor nodes which meet the requirements toward a sink since the desired delivery speed is fixed. This paper proposes a scheme to pass the area using time gain which occurs by the nature of the existing real-time transmission scheme. Thus, in the area, a sending node could make full use of nodes which do not satisfy the requirements. In the end, the packet passes across the area with a lower speed than the desired delivery speed. The simulation results show that the proposed scheme is superior in terms of real-time transmission success ratio to the existing schemes.
