Delay-Based Network Utility Maximization

Delay-Based Network Utility Maximization ABSTRACT: It is well known that max-weight policies based on a queue backlog index can be used to stabilize stochastic networks, and that similar stability results hold if a delay index is used. Using Lyapunov optimization, we extend this analysis to design a utility maximizing algorithm that uses explicit delay information […]


A Highly Scalable Key Pre-Distribution Scheme for Wireless Sensor Networks

A Highly Scalable Key Pre-Distribution Scheme for Wireless Sensor Networks ABSTRACT: Given the sensitivity of the potential WSN applications and because of resource limitations, key management emerges as a challenging issue for WSNs. One of the main concerns when designing a key management scheme is the network scalability. Indeed, the protocol should support a large […]
