Providing Privacy and security of Wireless sensor network using ACTOR nodes

Wireless Sensor Networks (WSN) consists of large number sensor nodes. Wireless sensor nodes are generally deployed in the far places like forests deserts and used to sense the network conditions like temperature pressure etc. In such far places it is very difficult to recharge or replace the battery of the sensor node.  The sensor nodes are battery powered devices, they communicate over a wireless medium and consumes energy during data transmission. The various types of active and passive attacks are possible in routing the data from source to sink. In this paper, we propose new technique to prevent these attacks. The mobile sinks is been deployed in the network which collect data from the sensor node and deliver data to fixed base station. In the proposed technique, the data privacy is ensured in the mobile sink. KEYWORDS WSN, Mobile Sinks, Sensor node, Query, batter

Strengths and Weaknesses of Prominent Data Dissemination Techniques in Wireless Sensor Networks

Data dissemination is the most significant task in a Wireless Sensor Network (WSN). From the bootstrapping stage to the full functioning stage, a WSN must disseminate data in various patterns like from the sink to node, from node to sink, from node to node, or the like. This is what a WSN is deployed for. Hence, this issue comes with various data routing models and often there are different types of network settings that influence the way of data collection and/or distribution. Considering the importance of this issue, in this paper, we present a survey on various prominent data dissemination techniques in such network. Our classification of the existing works is based on two main parameters: the number of sink (single or multiple) and the nature of its movement (static or mobile). Under these categories, we have analyzed various previous works for their relative strengths and weaknesses. A comparison is also made based on the operational methods of various data dissemination schemes
