Efficient Allocation of Slot using Medium Access Control Protocol

With the emergence of advanced technology, the need for improving the energy has been of paramount significance, especially in the area of wireless sensor network. The most of the energy consumed in the sensor node caused by transceiver. The efficient Medium Access Control protocol can reduce an additional energy consumption of transceiver. In this paper, we introduce an energy efficient packet scheduling (EEPS) algorithm using dynamic slot allocation (DSA). In the EEPS, head node checks empty available slots and assigns the slots those nodes that are in waiting list. Based on this algorithm, empty available slots are utilized efficiently for saving the energy consumption and improving the throughput performance. The proposed idea is implemented using network simulator (NS3) and compared with other known existing protocols

Simultaneous Priority and Detection Based Carrier Sense Multiple Access Protocol

Carrier Sense Multiple Access (CSMA) protocol, along with collision detection in wired communication, helps in further increasing the efficiency of channel usage. It helps in terminating its transmission over the channel immediately once collision is detected, releasing the channel for other useful transmissions. Whereas in wireless communication, the packet collision cannot be detected until the completion of the entire transmission. To detect the collision immediately, the robust mechanism is requested. In this paper, we introduce Simultaneous Priority and Detection based Carrier Sense Multiple Access (SPD-CSMA) protocol to establish an efficient connection and immediate collision detection. The SPD-CSMA handles the situation using an additional antenna and a unique code message. SPD-CSMA is also supported with Shortest First (SF) algorithm for prioritizing the transmission. The proposed SPD-CSMA approach is validated by using NS3 on Ubuntu 13.10 operating system. The experimental results demonstrate that a reduced collision rate helps with improving the Quality of Service

Multi-Biometric System Using Fuzzy Vault

Advancement of electronic media not only improved our living standard, but created several amenities that makes work bit easier. On the other hand, media faces several challenges. Biometric systems are promising technology with accurate data and secure features. However, many existing Biometric systems based on a single authentication process have higher vulnerability than a Multi-biometric systems. Multi-biometric systems accumulate evidence from more than one biometric trait in order to recognize a person. They provide higher recognition accuracy and larger population coverage. Multi-biometric systems store multiple biometric templates for each user, which results in increased risk to user privacy and system security. To secure the individual biometric template by using the fusion method to store the data. The fuzzy vault is proposed. By the end of this paper we would like to propose an idea to further improve the data security and also make this process take the less time
