Ensuring Higher Security for Gathering and Economically Distributing the Data in Social Wireless Sensor Networks

Abstract

Wireless Sensor Networks(WSNs) is spatially distributed in sensor nodes without relay. A Mobile Data Investor, M-Investor is used to gather the data from sensor node and upload the data into data sink. When one M-Investor is moving, gathers the data from each and every nodes of entire network and upload the data into data sink. Also it raises distance/time constraints. The proposed system uses multiple M-Investors that are formed by portioning a network into a number of small sub networks. Each of them gathers the data by dynamically moving through a number of smallest sub tours in the entire network, upload the data into a data sink and it reduces distance/time constraints. The proposed system introduces supportive caching policies for minimizing electronic Data provisioning cost in Social Wireless Sensor Networks (SWSNET). SWSNETs are formed by mobile data investor, such as data enabled phones, electronic book readers etc., sharing common interests in electronic content, and physically gathering together in public places. Electronic object caching in such SWSNETs are shown to be able to reduce the Data provisioning cost which depends heavily on the service and pricing dependences among various stakeholders including Data providers (DP), network service providers, and End Customers (EC).
