OLSR-RAIP5: Optimized Link State Routing with Redundant Array of Independent Paths 5

The improvement of data routing performances and security in mobile networks mainly depends on the quality and type of message transmitted and also on the routing algorithms used. In Mobile Adhoc Networks (MANET), there are a lot of constraints that must be considered to improve quality and security of mobile communications. In this paper, we propose a new approach to enhance quality, reliability and security of mobile communications based on a multipath routing protocol inspired on the RAID5 technology. We propose a new algorithm for packet segmentation and routing data via multiple disjoint paths. This provides better security and ensures greater reliability of the information exchanged in a MANET. We have tested our proposition and done some simulations on the OLSR protocol which is widely used in context of MANETs. Through conducted simulations, we have shown that our proposed solution offers better reliability and security than the standard OLSR protocol.
