Identifying the Direction of Wind in Wireless Sensor Networks

This paper describes a novel method for determining the direction of a phenomenon such as wind in wireless sensor networks (WSNs). The method is based on a structured grid topology and mainly depends on analyzing the timestamp of each node in the grid at the base station. The topology and the routing protocol are evaluated by simulation using OmNet++ and MiXiM 2.1 framework. Throughput, latency and average power consumption are measured and compared in order to investigate the efficiency of our method.
