the devices on the network can be thought of as a node; each node has a unique address. Networks may be classified according to a wide variety of characteristics‚ such as the medium used to transport the data‚ communications protocol used‚ scale‚ topology‚ and organizational scope. Communications protocols define the rules and data formats for exchanging information in a computer network‚ and provide the basis for network programming i.e. for data communication between multiple networks‚ as well

that usually has the means to prevent echo-related problems. Twisted pair cables typically used in star topologies are not as immune to interferences as coxiale cable. A single device or cable failure will not bring down the network. Expensive because of additional cabling and central hub require. If the centralize device fails the entire system is affected. Ring topology is an active topology because each computer repeats (boosts) the signal before passing it on to the next computer. Adding additional

Size and cost constraints on sensor nodes result in corresponding constraints on resources such as energy‚ memory‚ computational speed‚ and communications bandwidth. The topology of the WSNs can vary from a simple star network to an advanced multi-hop wireless mesh network. The propagation technique between the hops of the network can be routing or flooding. The major technologies used in IWSN market are Wireless HART‚
