Comprehensive Analysis of Routing Protocols for the Application Layer of LTE

LTE, an acronym for Long Term Evolution is a standard developed by the 3rd Generation Partnership Project (3GPP) for high peak data rates with a downlink speed of up to 150 megabits per second (Mbps) and an uplink speed of up to 50 Mbps. LTE is a way for cellular communications to operate at that high data rate. Routing is an important operation performed to route the data packets from the source node to destination node in any network. Hence there is a need for a protocol/algorithm to determine the best way to transfer the data. Routing protocols determine the best route to transfer data from one node to another. In this paper, a comparative study of the routing protocols for the application layer of LTE network is done. The protocols analyzed are Optimized Link State Routing (OLSR) and Routing Information Protocol (RIP). A study and comparison of the parameters are done based on the simulation results. The different performance metrics analyzed are Packet delivery ratio, Throughput, Average end-to-end delay and Jitter. The simulation results show that the best routing protocol w.r.t all the parameters analyzed is RIP.
