The current Internet service models is based on a few assumptions such as the existence of an end to- end path between a source and destination pair, and low round-trip latency between any node pair. However, these assumptions do not hold in some emerging networks. Like battlefield ad-hoc Networks in which wireless devices carried by soldiers operate in hostile environments where jamming, environmental factors and mobility may cause temporary disconnections. To allow nodes to communicate with each other in these extreme networking environments, we proposed a new architecture called the disruption tolerant network (DTN).In some application scenarios, there are some ‘storage nodes’ in the network where useful data is stored or replicated so that other regular mobile nodes can access the necessary information quickly and efficiently. A requirement in some security-critical applications is to design an access control system to protect the confidential data stored in the storage nodes or contents of the confidential messages routed through the network. Overcome this problem, in this project we propose a cipher text-policy ABE (CP-ABE) provides a scalable way of encrypting data such that the encryptor defines the attribute set that the decryptor needs to possess in order to decrypt the cipher text. Thus, different users are allowed to decrypt different pieces of data per the security policy. The proposed scheme have attribute revocation enhances backward/forward secrecy of confidential data, the coordination of attributes issued from different authorities and avoid third party compromised with key authorities. The proposed scheme to securely and efficiently manage the confidential data distributed in the disruption- tolerant military network.Keywords

Objectives: The main objective of the power distribution system is to reduce the loss in order to improve the system efficiency, alleviate the cost and increase the consumer satisfaction. Methods/Analysis: Power loss mainly depends on type of the load and its pattern. Load unbalance on distribution feeder leads to current raise in the heavily loaded phase, over voltage in the lightly loaded phase and neutral current and mal functioning of protection equipment. Findings: In power distribution energy management, phase balancing is one among the techniques available to reduce the loss incurred by load unbalance. Phase balancing is a concept of re-phasing service laterals such that load on three phases is balanced. Application/Improvement: The study mainly deals with phase balancing of secondary distribution feeder by rearranging the connections of consumer load/ service laterals. The algorithm is designed to handle time varying loads with an objective of loss reduction and minimum number of phase moves.Keywords

Different plant extracts were studied in vitro for their efficiency of suppressing F.oxysporum causing rhizome rot of turmeric and role of Total Phenolic Content (TPC) of plant extracts in the antifungal activity, is also studied. The selected plant leaf extracts have shown significant antifungal activity (in vitro) against the mycelial growth of F.oxysporum causing rhizome rot of turmeric. Among them, Ocimum sanctum exhibited maximum antifungal activity of 99.45% inhibition over the pathogen and it has high total phenolic content of 280mg/100g. C.procera exhibited minimum inhibition percentage of 79.68. It has also least TPC of 75mg/100g.Keywords
