Abstract [en]

Providing reliable routing in MANET is ever challenging. Protocols have to trade off between routing accuracy and update frequency. Mobile devices have resource limitations in terms of battery power, processing, and storage. Efficient utilization these resources is one of the key challenges. Routing protocol have to balance between update frequency and routing accuracy.

This thesis work presents reliable routing in mobile ad hoc networks. As a part of thesis work Neighborhood Fisheye State Routing (NFSR) protocol is implemented as a proof-of-concept. Neighborhood concept is improved which uses reliable metric for calculating path stabilities and nds reliable path to destination. Link emulation for emulating wireless link instabilities in terms of packet loss is implemented. Finally, self-healing and self-optimization for NFSR is validated. Topology and forwarding table computing time is evaluated in dierent sets of basic topologies.
