Dans cette lettre, nous révélons le trafic de contrôle redondant dans le protocole de routage à état de lien optimisé (OLSR) pour MANET. Les messages de contrôle de topologie (TC), qui occupent une partie du trafic de contrôle dans OLSR, sont utilisés pour échanger des informations de topologie avec d'autres nœuds. Les messages TC sont générés et transmis uniquement par les nœuds qui ont été sélectionnés comme relais multipoints (MPR) par au moins un nœud voisin. Ces nœuds sélectionnés comme MPR sont appelés expéditeurs de messages TC dans cette lettre. Une des solutions pour réduire le nombre de messages TC consiste à réduire le nombre d'expéditeurs de messages TC. Nous décrivons un algorithme non distribué pour minimiser le nombre d'expéditeurs de messages TC. Grâce à la simulation de scénarios de nœuds statiques, nous montrons que 18 % à 37 % des expéditeurs de messages TC dans OLSR basé sur RFC sont redondants. En éliminant les expéditeurs de messages TC redondants, le nombre de paquets TC, dont chacun contient un ou plusieurs messages TC, est également réduit de 19 % à 46 %. Nous montrons également que les scénarios à haute densité ont plus de redondance que les scénarios à faible densité. Cette observation peut aider à envisager une sélection coopérative MPR en OLSR.

Abstract: In this letter, we reveal redundant control traffic in the optimized link state routing protocol (OLSR) for MANET. Topology control (TC) messages, which occupy a part of control traffic in OLSR, are used to exchange topology information with other nodes. TC messages are generated and forwarded by only nodes that have been selected as multipoint relays (MPRs) by at least one neighbor node. These nodes selected as MPRs are called TC message senders in this letter. One of solutions to reduce the number of TC messages is to reduce the number of TC message senders. We describe a non-distributed algorithm to minimize the number of TC message senders. Through simulation of static-node scenarios, we show 18% to 37% of TC message senders in RFC-based OLSR are redundant. By eliminating redundant TC message senders, the number of TC packets, each of which contains one or more TC messages, is also reduced from 19% to 46%. We also show that high density scenarios have more redundancy than low density scenarios. This observation can help to consider a cooperative MPR selection in OLSR.
