SN can form the base of cloud computing, distributed computing, and Next Generation Networks (NGN). For this, sink nodes can be used as a gateway to interconnect other networks, and backbone scenarios for more connected networks. Router equipped with sensing capabilities can work for saving powers and sleep when there is no activity in the network or so.
Transport layer is specially needed when the system is planned to be accessed thru Internet or other external networks. Nodes route data destined ultimately for the BS thru intermediate nodes, thus nodes can act as routers for other nodes’ data in addition to sensing the environment and other phenomena. This gives a good glimpse of the NGN and possibilities of future web-invasion of sensor network for and with distributed computing.
