DATA DISCOVERY AND CIRCULATION PROTOCOL IN WIRELESS SENSOR NETWORKS

摘要

A data discovery and circulation protocol for Wireless Sensor Networks (WSNs) play a major role for updating the configuration parameters of the sensor nodes and a distributing commands to the Sensor nodes. Circulation protocols are capable of self organizing as the WSN are deployed in critical zones and rural areas where the manual reprogramming of nodes are complicated to configure. All existing data discovery and circulation protocols have two shortfalls one which is that the, existing protocols are based on the centralized manner, i. e. data items can only be circulated by the base station. Such approach is not sufficient for emergent multiuser Wireless Sensor Networks. Secondly, those existing protocols were designed with a lack of proper security and hence adversaries can easily launch attacks to attack the network suddenly. This paper proposes the more secured and distributed Data Discovery and Circulation protocol named DiDcip. This protocol allows the network owner to authorize the various network users with different privileges to circulate Data items to the Sensor node efficiently and directly. This protocol enables more security for the Data.
