Multipath Optimized Link State Routing for Mobile Adhoc Networks
[attachment=32329]
Abstract
Multipath routing protocols for Mobile Ad hoc NETwork (MANET) address the problem of scalability, security (confidentiality and integrity), lifetime of networks, instability of wireless
transmissions, and their adaptation to applications.
Multipath OLSR (MP-OLSR), is a multipath routing protocol based on OLSR.
Introduction
Staying connected anywhere to a network is really themain objective of mobile technologies.
Mobile Ad hoc NETwork (MANET) may provide a solution.
With MANET, all nodes are routers and forward packets without any infrastructure.
This kind of network is spontaneous, self-organized
and self-maintained.
Simulation and performance evaluation
The Qualnet simulator is used for our simulation.
To compare the performances of the protocols, the following metrics are used
1. Packet delivery ratio
2. Average end-to-end delay
3. Average time in FIFO queue
4. Distribution of delay of received packets
Compatibility between MP-OLSR and OLSR
To ensure the compatibility between the two protocols
OLSR and MP-OLSR, we propose an implementation of MPOLSR protocol based on IP-source routing .
The IP protocol supports two forms of source routing:
1. Strict source routing
2. Loose source routing
Conclusion
The MP-OLSR guarantee quality of service and a possible backward compatibility based on IP-source routing.
The MP-OLSR can effectively improve the performance of the network and also be compatible with OLSR.
From the security point of view, we can argue that the multipath approach can increase confidentiality.
For integrity purpose, a redundant coding can be integrated to the routing protocol in order to ensure an higher delivery rate.
