Implementation of AODV routing protocol in sensor wireless networks

This paper presents an implementation of the Ad hoc On-Demand Distance Vector (AODV) routing protocol in conditions of sensor wireless networks. AODV is a reactive on-demand distance vector protocol and utilizes partially connected mesh network topology. Designed stack is intended for purposes of applications that require quick adaptation to dynamic link conditions. Protocol implementation was primarily focused on embedded systems with constrained memory and computational resources and was intended to be easy portable to other platforms. For testing purposes, designed stack was attached to link layer of SimpliciTI stack and compiled for CC430 microcontroller with on-chip sub-1-GHz RF transceiver supplied by Texas Instruments Company. This work was motivated by the need of a simple implementation of the routing protocol intended for tiny systems and utilizing mesh network topology which will quickly adapt on fast node position changes.
