IRDT-GEDIR: Next-Hop Selection in Intermittent Wireless Multihop Sensor Networks

Abstract

IRDT (Intermittent Receiver-driven Data Transmission) realizes low-power communication between neighbor sensor nodes. This paper proposes combination IRDT-GEDIR of IRDT and GEDIR which is an on-demand location-based ad-hoc routing protocol. Here, pseudo speed of data message transmission is applied for next-hop selection in an intermediate node and on-line determination of its next-hop node is realized by calculation of expectation of pseudo speed provided by its neighbor nodes which have not yet enter their active mode. This paper discusses how the expected pseudo speed and the reduction of data message transmission delay is evaluated. In addition, the performance of IRDT-GEDIR is evaluated in simulation experiments.
