An Energy-oriented Node Characteristics-Aware Routing Algorithm for wireless LAN

A growing number of different technology-supported wireless networks are being deployed everywhere including many public areas, people of different ages are using increasingly complex battery-powered devices and various rich media networked applications have an exponentially growing popularity. In this context of high diversity and heterogeneity of devices, networks and applications, energy is a limited and highly valuable resource on which high quality service provisioning to users is highly dependent. This paper proposes an Energy-oriented Node Characteristics-Aware Routing Algorithm (ENCARA) which considers energy-related node characteristics in the routing process. ENCARA differentiates nodes by their characteristics and will conserve energy of those nodes with critical energy constraints, while maintaining the overall routing performance at high levels.
