Abstract

We propose a new multi-hop routing protocol for wireless sensor networks, suited for monitoring and control applications. The aim of this research is to adapt flat and hierarchical architectures to create a new hybrid that draws on current protocol theories. The protocol uses a hybrid network structure to achieve scalability and is source initiated along with time driven reporting to reduce the number of packet transmissions. The protocol incorporates a link quality estimation algorithm, which enables only the nodes with high quality symmetric links to be chosen for routing. Route selection is calculated using both hop count and link quality as routing metrics. The protocol is also designed such that it is computationally simple, reliable, energy aware, does not impose any special hardware prerequisites and most importantly credible. Its credibility was verified by performing a series of field tests in a real world operating environment.
