On myopic sensing for multi-channel opportunistic access: structure, optimality, and performance
We consider a multi-channel opportunistic communication system where the states of these channels evolve as independent and statistically identical Markov chains (the Gilbert-Elli...

Architectural Framework Design for Authentication Mechanism in Mobile Adhoc Networks (MANETs)
Wireless ad-hoc networks do not rely on a pre-existing network structure and are characterized by dynamic changes in the topology. This characteristic makes it difficult to perform...
