This paper presents an energy aware routing protocol (EARP) whose purpose is to minimise a metric that combines the total consumed power in the network and the QoS bounds requested by the incoming flows. The algorithm performs in a fully distributed manner thanks to the functionalities provided by the Cognitive Packet Network (CPN) which runs at each node of the network. Measurements on an expe...

Nodes in a sensor network, operating on power limited batteries, must save power to minimize the need for battery replacement. We note that the range of transmission has a significant effect on the power consumption of both the transmitting node and listeners. This paper first presents a Geographical Power Efficient Routing (GPER) protocol for sensor networks. Each sensor node makes local decis...

With the increasing volume and volatility of Internet traffic, the need for adaptive routing algorithms has become compelling lately. An adaptive routing algorithm controls the rate at which traffic is placed on forwarding paths in concert with the actual user demands, making it possible to avoid congestion even when no information on expected traffic is available. In this paper, we present a n...
