A wireless sensor networks are made up of sensors which are usually energy constrained one. The lifetime of the network is directly proportional to the energy efficiency of these nodes and hence a lot interest has been focused to effectively prolong the longevity of the individual node and network lifetime. Several WSN protocols and clustering algorithms have been proposed on how to optimally select the cluster heads in the sensor networks. In this paper EECHP protocol is proposed by combining the Particle Swarm Optimization (PSO) and Artificial Bee Colony (ABC) algorithm for enhancing the lifetime of wireless sensor networks. Experimental results show that the proposed approach EECHP protocol performs better than the ECHS, DECP and LEACH algorithms. A significant increase of network lifetime has been achieved and improved the First Node Death (FND) and Last Node Death (LND) respectively.Keywords

- Improving Security and Verifiability of Stored Data in Cloud
Abstract Views :171 |
PDF Views:2
Large amount of computing and services along with storage facility is provided by the CSPs. Unlike the normal traditional computing where the data was usually stored in one location, the data storage in Cloud is likely stored in several locations and is accessed through the high speed networks. In order to ensure security, we propose a novel way of improving the security of the stored data in cloud computing.
The proposal speaks of using Reed Solomon error correction codes for providing reliable data by maintaining redundant files in various locations. Also, we improve the verifiability by utilizing Halton sequence rather than pseudo random data, thereby filling the region avoiding large gaps that generally occur in pseudo random generator.
