| Popis: | In this article, we propose a novel extension for the OLSR routing protocol, "Multi-Level OLSR" (ML-OLSR): it introduces a hierarchy between links, where some links are preferred to others. The objective is that the network consisting of links of most preferred levels (higher levels) operates as if the links of the lower levels did not exist, and when this is not possible, the use of lower level links is minimized.The main challenge is that OLSR not only uses shortest path for route calculation by default (which conflicts with avoidance of some specific links), but more importantly, also uses it implicitly, in the multi point relays (MPR). The major contribution of ML-OLSR is to consistently and concisely modify OLSR protocol specification, while strictly enforcing the link hierarchy.Our motivation and one of the applications are military tactical networks: this feature has numerous use cases for organizing future tactical MANETs, and is more general and applicable than the classical notion of hierarchy within nodes. |
