Abstract: Real-time geographic routing is one of the most popular examples relying on a greedy algorithm to deliver real-time data in wireless networks. Each sender node decides a next-hop node among one-hop neighbours in stateless manner. However, this sender-side decision paradigm suffers from periodic and network-wide beaconing to discover neighbour nodes. To overcome the limitation, this paper suggests a passive and greedy beaconless real-time routing, called PGBR. To forward real-time data by receiver-side selection, PGBR focuses on two major challenging issues: a delay estimation procedure and a contention function design. The delay estimation procedure estimates both waiting delay and packet transmission delay used for the contention function. PGBR also redesigns receiver-side contention function with deliberating the estimated delay and discuss combinations of important metrics for the contention. The experimental results show that PGBR could improve the energy-efficiency as well as keeps high delivery deadline success ratio.

Keywords: beaconless; real-time; delay estimation; contention function; routing protocol.
