This paper presents an analytical model for estimating the network convergence time of IPv6 Routing Protocol for Low-power and Lossy Networks (RPL) in a static chain topology network of IEEE 802.15.4 nodes, in the presence of bit errors. The model presented is validated by extensive simulation results. We show that performance degradation may be noticed by a user for BER values around or greater than...
In cognitive sensor networks, achieving consensus among the sensor nodes without requiring centralized control is an important attribute that can enable quick and reliable network decisions. Decentralized consensus building can be achieved through iterative information exchange among sensor nodes. While much of the literature has concentrated on developing theory, minimizing the number of iterations...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
