A Survey: Location Based Protocols for Wireless Sensor Networks

The application of sensor nodes is growing rapidly in present environment. There is a need of sensor networks to collect data in effective way. The requirement for sensor networks depends on various factors based on their applications. The need for robustness and scalability leads to the design of localized algorithms, where sensors communicate with other senso nodes in restricted vicinity and have at best an indirect global view. Sensor nodes are addressed by means of their locations in location based protocols. Energy consumption is estimated by the distance between two sensor nodes and so location information is essential. Some queries from sensor nodes are also location specific and so location based sensors find a wide number of applications. In this paper, some location based protocols and their limitations were discussed
