A STUDY ON LOCATION-BASED ROUTING PROTOCOL FOR WSN

A wireless sensor network (WSN) is a wireless network formed by distributed autonomous devices using sensors to oversee physical or environmental conditions. Wireless sensor networks consist of independent small-size Sensor nodes. Each sensor node collects data and sends it to different destinations. . In Wireless sensor networks, the sensor nodes have a limited transmission range as well as processing, energy resources and storage capabilities. The routing protocols for wireless sensor networks maintain the routes in the network, which might be depending on the application and network architecture and ensure reliable communication under these conditions. In this topic we explain location based routing protocols for Wireless sensor networks. In location-based protocols, address the location of sensor node. Location information about sensor nodes is required for sensor networks to calculate the distance between a pair of nodes so that energy consumption can be estimated. We present location-aware routing protocols for Wireless sensor networks.
