Data Freshness in Mixed-Memory Intermittently-Powered Systems

This paper proposed an integrity and privacy preserving data aggregation algorithm for WSNs, which is called IPPDA. First, it attached a group of congruent numbers to the sensing data in order to execute integrity checking operated by sink node using Chinese remainder theorem (CRT); then it computed the hash function-based message authentication codes with time and key as the parameters to satisfy data freshness; finally, it adopted a homomorphic encryption scheme to provide privacy preserving. The simulation results show that IPPDA can effectively preserve data privacy, check data integrity, satisfy data freshness, and get accurate data aggregation results while having less computation and communication cost than iCPDA and iPDA.

Practical Implications

The main purpose of this paper is to work with a proposal that small and medium-sized enterprises are aware of the importance of design and also attribute an important role to it in the competition in the future. Is design really a company’s potential and will it be of greater importance to companies? The approach is based on theoretical sources and completed studies dealing with design management and its relation to prosperity. Two hypotheses, that verify the thesis, are statistically tested on the significance level 0.05. Practical implications confirm the thesis and undisputedly support the issue of the importance of design for business success in small and medium-sized enterprises. Both in the area of increasing the competitive potential and the increasing importance in the future. Therefore, future commercial impact is proven by statistical tests. The originality of the article lies primarily in the data freshness in connection with the cur-rent economic situation. There is a prediction that the Czech gross domestic product is at its peak and significant growth is not expected. It means that this is the last opportunity for companies to prepare for hyper-competition. One of the power that companies have at their disposal to assure a place in the market is design management.

Data Freshness

The need for security in communications is in fact not new. This need has existed in military communications for thousands of years. In this paper, we focus on network protocols that provide security services. Wireless sensor network is an emerging technology that shows applications both for public as well as military purposes. Monitoring is one of the main applications. A large amount of redundant data is generated by sensor nodes. This paper compares all the protocols which are designed for security of wireless sensor network on the basis of security services and propose an improved protocol that reduces communication overhead by removing data redundancy from the network. By using the message sequence number we can check whether it is old message or new message. If the message is old then no need to send that message thereby reducing overhead. It also integrates security by data freshness in the protocol.
