Abstract

Power Conservation is one of the most important challenges in wireless sensor networks. We propose two minimum-energy routing algorithms CODE and SIDE. CODE (COordination-based Data dissemination for sEnsor networks) addresses mobile sinks and considers energy efficiency not only in communication but also in idle-to-sleep state. SIDE (SInk cluster-based data Dissemination for sEnsor networks) addresses numerous stationary sinks and relies on loosely resource-constraints of a sink to ease the cost burden of sensor nodes. Our simulation results show that both algorithms reduce energy and prolong the network lifetime.
