Enhancing Network Lifetime in Wireless Sensor Networks Adopting Elephant Swarm Optimization

Enhancing the lifetime of wireless sensor networks had baffled researchers for quite some time now. The authors of this research manuscript draw inspiration from the behavior of large elephant swarms and incorporate their behavior into wireless sensor networks. The complex elephant swarm behavior is incorporated using a cross layer approach. The elephant optimization discussed in this paper enables optimized routing techniques, adaptive radio link optimization and balanced scheduling to achieve a cumulative enhanced network performance. The proposed elephant swarm optimization is compared with the popular protocol. The experimental study presented proves that the Elephant Swarm Optimization technique enhances the network life time by about 73%

RASCP: Providing for a Secure Group Communication Plane Using RFID

Predominantly large distributed networks currently provide support for group oriented protocols and applications Regardless of the type of distributed network there is a need to provide communication privacy and data integrity to the information exchange amongst the group members This paper introduces a protocol named Authentication based Secure Communication Plane adopts the commutative RSA algorithm to maintain data integrity The proposed protocol not only eliminates the overheads resulting from key distribution and key compromise attacks but also provide for information security in the presence of colluded group members Radio Frequency Identification tags is used for group member identification The RACP protocol is compared with the RFID extended Secure Lock group communication protocol and its efficiency in terms of the computational complexity involved is discussed in this pape
