Location based Routing Protocols and its Performances in Wireless Sensor Networks: An Investigation

A Wireless Sensor Network (WSN) is a network that comprises of independent sensor nodes which communicate with one another to share data. The routing techniques, regarded as a fundamental component of WSNs, govern how a node can transfer data in real-time. Location-based routing is one of the routing strategies used in wireless sensor networks to convey data by utilizing the position information of the node. In this article, a variety of location-based routing protocols such as GAF, GEAR, GPSR, and DREAM used in wireless sensor networks are considered for the study. In addition to that, the performance of selected location-based protocols is investigated using simulations based on several network parameters such as network delay, data loss ratio, data delivery ratio, and network throughput against different sizes of the network. The simulation results prove that, based on only the network parameter, picking up the best protocol is critical because the performance of each protocol also depends on the size of the network.
