Abstract: In this paper, we propose a QoS aware ORRP (Q-ORRP) routing protocol to minimise the energy consumption by reducing overhead and delay. The method of intersection of signals is used for transferring the data with improved QoS. Sink is enabled with orthogonal transmission, in which it sends an interest request message to all neighbouring nodes in all orthogonal directions. This process continues until the interest request matches with intended data. Then, the node sends the interest acknowledgement back to the sink through the reverse path. The intersection point of these two messages is considered as the rendezvous point (RP). When the RP receives these packets, it changes their direction and sends them toward destination node. Finally, sink establishes data dissemination tree towards the source through RP nodes. RPs with high residual energy and queue lengths are selected for establishing tree, so that the data transmission will be energy efficient and robust.

Keywords: orthogonal routing; directional antennas; rendezvous point; energy efficiency; QoS; data aggregation; wireless sensor networks; WSNs; quality of service; energy consumption; overhead reduction; delay reduction; wireless networks.
