Layered architecture solution

Recent advances in wireless communications and electronics have enabled the development of low cost, low power wireless sensor nodes, which are small in size and have the capability to measure quantities, process measurement data, transmit within short distances and actuate peripherals. The project aims to apply wireless sensor networks to several fields, such as: industrial monitoring and control home and building management security and military sensing precision agriculture
