Through sensing and utilizing available network resources, cognitive network can obviously increase network performance. In this paper, a distributed on-demand routing protocol with traffic awareness (TACR) is proposed for cognitive wireless network. This routing protocol establishes the path based on the cognition and reasoning of traffic loads in a network and it also meet quality of service (QoS)...
This paper presents an implementation of the PGBR routing protocol within the ns-3 simulator. Broadband convergence networks can offer a solution for multiple service classes through integrated heterogeneous networks. However, to prepare this for the future variability in traffic demand, a dynamic routing protocol that enhances scalability, QoS awareness, and easy roadmap to deployment if necessary...
A principal factor in sensor network design is energy efficiency. In this work, we propose to extend the lifetime of sensor networks using appropriate choice of sensor node distribution. The key idea of our scheme is to deploy more nodes in areas of extensive energy usage. Using this scheme of sensor node distribution, we use probabilistic angular routing to route data packets from the sensor nodes...
