ENERGY CONSUMPTION IN WIRELESS SENSOR NETWORKS USING BEACONLESS ROUTING

Abstract: Wireless sensor networks are prevalent and cost-effective. However, they face RF interference from environmental noise and energy constraints. Routing protocols for such networks must overcome these problems to achieve reliability, energy efficiency and scalability in message delivery. Multi hop WSNs use shortest-path routing, since operation is often over long unattended periods so the protocol must be energy efficient.
An Enhanced Forward Aware Factor-Energy Balanced Routing Method (EFAF-EBRM) based on Data aggregation technique that has some key aspects such as a reduced number of messages for setting up a routing tree, maximized number of overlapping routes, high aggregation rate, and reliable data aggregation and transmission. According to data transmission mechanism of WSN, we quantify the forward transmission area, define forward energy density which constitutes forward-aware factor with link weight. For energy efficient transmission in event-driven WSN, data should be reduced. It requires proper routing method for reliable transmission of aggregated data to sink from the source nodes. Propose a new communication protocol based on forward-aware factor in order to determine next-hop node and IEAR routing algorithm is to reduce the number of transmissions and thus balancing the energy consumption, prolonging the network function lifetime and to improve QoS of WSN.
