Abstract
The Optimized Link State Routing (OLSR) protocol is a well-known route discovery
protocol for ad-hoc networks. OLSR optimizes the flooding of link state information
through the network using multipoint relays (MPRs). Only nodes selected as MPRs
are responsible for forwarding control traffic. Many research papers aim to optimize
the selection of MPRs with a specific purpose in mind: e.g., to minimize their
number, to keep paths with high Quality of Service or to maximize the network
lifetime (the time until the first node runs out of energy). In such analyzes often the
effects of the network structure on the MPR selection are not taken into account. In
this paper we show that the structure of the network can have a large impact on the
MPR selection. In highly regular structures (such as grids) there is even no variation
in the MPR sets that result from various MPR selection mechanisms. Furthermore,
we study the influence of the network structure on the network lifetime problem
in a setting where at regular intervals messages are broadcasted using MPRs. We
