Improved GPSR routing protocol based on weight function in shipborne ad hoc networks

Abstract

The network topology of the shipborne ad hoc network changes rapidly, which leads to instability of the data transmission link. Therefore, finding a stable data packet transmission link has become a hot research topic. This paper improves on the basis of the original GPSR routing protocol, and evaluates the link quality by selecting four metrics, including direction of neighbouring ship, link risk, density of neighbouring ship and proximity. The analysis results show that the improved protocol is superior to the GPSR routing protocol in terms of packet delivery rate.
