evolutionary development step in building, utilities, industrial, home, shipboard, and transportation systems automation Like

any sentient organism, the smart

environment relies first and foremost on sensory data from the real or1d Sensory data comes from multiple sensors of

different modalities in distributed locations

2.1 Network Topology

Mesh networks

networks that generally allow transmission only

to a node’s nearest neighbors The nodes in

these networks are generally identical, so that mesh nets are also referred to as peer-to-peer nets.

networks of wireless sensors that are distributed over a geographic region
