IRDT-GEDIR: Next-Hop Selection in Intermittent Wireless Multihop Sensor Networks
Intermittent Receiver-driven Data Transmission (IRDT) 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. Here, for estimation of pseudo speed for neighbor nodes which are still in their sleep mode, a solution of the secretaries problem is applied. Finally, a brief evaluation of the performance of the proposed IRDT-GEDIR in one-hop transmissions of data messages results in reduction of transmission delay.
