الملخص الانجليزي
Vehicle Ad Hoc Networks (VANETs) have become a viable technology to improve traffic flow and safety on
the roads. Due to its effectiveness and scalability, the Wingsuit Search-based Optimised Link State Routing
Protocol (WS-OLSR) is frequently used for data distribution in VANETs. However, the selection of
MultiPoint Relays (MPRs) plays a pivotal role in WS-OLSR's performance. This paper presents an
improved MPR selection algorithm tailored to WS-OLSR, designed to enhance the overall routing
efficiency and reduce overhead. The analysis found that the current OLSR protocol has problems such as
redundancy of HELLO and TC message packets or failure to update routing information in time, so a WSOLSR routing protocol based on improved-MPR selection algorithm was proposed. Firstly, factors such as
node mobility and link changes are comprehensively considered to reflect network topology changes, and
the broadcast cycle of node HELLO messages is controlled through topology changes. Secondly, a new
MPR selection algorithm is proposed, considering link stability issues and nodes. Finally, evaluate its
effectiveness in terms of packet delivery ratio, end-to-end delay, and control message overhead. Simulation
results demonstrate the superior performance of our improved MR selection algorithm when compared to
traditional approaches.
