Evaluation of Topological Planarity and Reliability for Interference Reduction in Radio Sensor Networks
One of the key factors in distributed sensor networks is their reliability in packets delivery even in the event of failure of one or a few nodes. Another factor - often underestimated - is the intra-network interference experienced by individual nodes from other transmitting counterparts. Common network spanning algorithms, however, neither posses the reliability feature nor keep the interference at minimum. It can be demonstrated that by enforcing a planar network topology combined with the requirement of minimum-pathloss between connections, one can achieve a gain in Signal-to-Noise and Interference Ratio (SNIR) by a few decibels with respect to standards spanning methods.
