This paper reports extensive simulations of the dynamic routing techniques for optical burst switching (OBS) networks. It gives a summary of the already proposed algorithms and describes more broadly some of them. It introduces also a new one called the Weighted Link Congestion and Frequency (WLCF) algorithm. Our comparative simulations are performed using an in-house developed environment in which...
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...
