是olsr协议的改进版本,用于更好实现路由(Optimized Link State Routing (OLSR) protocol is
a table-driven proactive routing protocol for wireless mobile ad
hoc networks. The key idea behind this protocol is to reduce the
control message overheads by marking subset of neighbors as
Multi-Point Relays (MPRs). In this paper, we discuss problems
of OLSR or other routing protocols that are due to mobility of
nodes. We integrate our solutions to OLSR protocol and call it
as Position-based OLSR (P-OLSR). Performance evaluation of
OLSR and P-OLSR is done through NS simulation. Simulation
results show that P-OLSR outperforms OLSR with respect to
packet delivery, throughput, latency and normalized overheads)
