Efficient geographic routeless routing protocols with enhanced location update mechanism

Abstract

In this paper, we introduce and evaluate two efficient controlled routeless routing protocols: Static and Dynamic Channel Width. They combine Location-Aided Routing (LAR) and Received signal strength-Aided Flooding (RAF) protocols for effective deployment in the very challenging domain of Mobile Ad hoc Sensor Networks (MASNETs). Our new approach maintains different controlled routeless geographic routing protocols that construct a virtual broadcasting channel between source nodes and their destinations. Hence with no predefined source-destination route, i.e. routeless, only some of the sensor nodes inside the channel are allowed to contribute in forwarding packets. Promising simulation results show that our protocols are able to outperform RAF, LAR, and Beacon-less routing protocols with respect to energy consumption, packet delivery ratio and end-to-end delay.
