Abstract: In an Optimized Link State Routing (OLSR)-based mobile wireless
network, optimizing the flooding of broadcast messages is a challenging task
due to node's mobility and bandwidth resource consumption. To complement
existing solutions to this problem, the Multi-Point Relays (MPR) selection has
recently been advocated as a promising technique that has an additional feature
of reducing the number of redundant re-transmission occurring in the network.
This paper continuous on the investigation of an existing MPR-based solution,
arguing that by considering a cost factor as an additional decision parameter
in selecting the MPR nodes, the enhanced MPR selection algorithm leads to less
packet loss in the network. Simulation experiments are presented to validate
the stated goal, using the average packet loss ratio as the performance metric.
