Vijayanand Metri presented a seminar on wireless sensor networks under the guidance of Prof. Surekha of the computer science and engineering department at GEC Haveri. The presentation covered the introduction, architecture, types, characteristics, features, issues, applications, advantages, and disadvantages of wireless sensor networks. It discussed sensor nodes, ad hoc deployment, unattended operation, environmental monitoring, health monitoring, and concluded that WSNs consist of small sensor nodes that can solve many open issues practically and cost-effectively.
